dental crown

Need a dental crown? These appliances, sometimes called tooth crowns, are one of the most common dental services today. They serve to protect the sensitive inside portion of your teeth.

There’s a lot of misinformation and confusion out there about dental crowns. Can I glue a crown back on myself? How do I take care of my crown? What kind of crown should I get?

If you or your child needs a dental crown, what should you expect? What are your options?

By the end of this article, you’ll understand everything about crowns.

What is a dental crown, and why do I (or my child) need one?

Dental crowns cover teeth after damage or cosmetic issues. They’re used for several reasons—and you don’t always need a root canal to have a crown.

A dental crown is a cap made of inanimate material (typically porcelain or gold) shaped to look like and fit onto a tooth so that the inside of the tooth isn’t exposed.

Traditional caps cover the entire portion of your tooth, beginning at the gum line. Other options, called “3/4 crowns” or “onlays”, don’t cover the whole tooth.

Common reasons you might need a crown (sometimes called a tooth cap) include:

  • Blunt trauma that actually breaks teeth
  • A root canal in which the tooth is opened and the nerves and infection from inside the tooth are removed
  • A deep cavity
  • A large filling that leaves too little tooth material (on fillings, a good rule of thumb is that a filling ⅔ of the tooth wide or larger needs a crown)
  • The need for a bridge (crowns are placed on the two or four teeth on either side of a missing tooth to connect the dental bridge)

The purpose of a dental crown is to protect the inside of your tooth from future fracturing. Particularly for broken or greatly damaged teeth, crowns can improve your ability to chew and bite down on food.

Your child may need a crown on a baby tooth if:

  • S/he has a cavity but has trouble keeping up with good hygiene and a cavity-reversing diet. For children at high risk for further tooth decay, a crown may be preferred to other corrective procedures, especially if they would require general anesthesia. If your child has behavioral or mental issues that make normal dental care difficult, consider using dental crowns on baby teeth to protect them from cavities.
  • S/he has a cavity that can’t be filled. Root canals aren’t often necessary for baby teeth. For very decayed baby teeth, crowns can hold the tooth together until the adult tooth comes in.

Crowns are not the same as living teeth. Let’s look at the differences between teeth and crowns and everything else you need to know about dental crowns.

What is a dental crown procedure? Is it painful to have a crown put on your tooth?

Whether you’ve had a root canal or need a crown for other reasons, you’ll usually need two visits for the dental crowns procedure.

So, what is a dental crown procedure?

During your first visit, your dentist will use a numbing agent around the tooth that needs a crown. Then, s/he will file down your teeth so that the crown can fit properly. Finally, s/he will take an impression of your reshaped tooth using putty or paste.

You’ll also get a temporary crown that day which lasts 2-3 weeks until your second appointment. Once your dentist receives your manufactured crown, you’ll come back for a second visit to have the new crown put on. You may or may not be numbed for that process.

Getting a crown isn’t a very painful process, either at the dentist or once you get home. The most pain you should expect is a little tenderness in your gums.

Some dental offices use in-house crown manufacturing, allowing for only one visit rather than two separate ones.

The Differences Between Caring for Crowns and Caring for Teeth

Unlike crowns, teeth are living organisms. Teeth:

  • Are constantly remineralized and demineralized throughout every day (this happens at different rates depending on what you eat and your dental hygiene habits)
  • Wear at a consistent rate (about 10 microns per year)
  • Can be stained
  • Can be whitened (either extrinsically or intrinsically)

That’s because they are alive, just like any other tissue in the body.

Dental crowns are foreign objects used to protect the living part of a tooth when it becomes exposed. Depending on the material, a crown may or may not wear at all.

Its color doesn’t change, it can’t respond to blood flow or nerve activity, and it can’t be remineralized or demineralized—because it’s just not alive.

When you get a temporary dental crown meant to last just a few weeks, you can take care of it by:

  • Chewing on the other side of your mouth from your temporary crown
  • Not eating sticky or hard-to-chew foods
  • Sliding, rather than lifting, floss from between the crowned tooth on either side

Fortunately, the way you care for a permanent dental crown is the same way you care for your teeth. After the first hour and a half or so after a permanent crown is put on, it becomes a part of your dental structure.

Crowns need regular brushing and flossing. The inside of the tooth they protect does best when you support your oral microbiome. This means following good dietary and hygiene practices to help your mouth’s environment stay balanced (like tongue scraping, rinsing after eating acidic foods, using oral probiotics, etc.).

Why? Because crowns aren’t just cosmetic. You get a crown to protect your teeth from fracturing. Fractures are more likely when bacteria gets in the tiny space (called the margin) between tooth and crown. These bacteria have the potential to break down the living tissue inside.

If the tooth under your crown becomes decayed, the crown probably won’t stay on much longer. Preventing decay under your crown is one key to keeping your dental crowns as long as possible.

In addition, crowns can become a little tricky over time because of how they wear (or don’t wear) and other factors that impact a crown’s fit on the tooth.

FAQs About Dental Crowns

What kind of crowns are available, and which one is the best?

There are three basic types of crowns your dentist might recommend:

  • Metals: Dental gold is the best metal option, but some dentists also use other alloys such as chromium or nickel.
  • Porcelain: An all-porcelain or porcelain-fused-to-metal crown is the go-to option for visible teeth that need crowns.
  • Resin: Crowns made entirely from resin are a cheaper option than the others. But they’re cheap for a reason: these crowns often crack and/or need replaced a lot sooner.

What is the best type of dental crown? Porcelain crowns are most suitable for front teeth and gold crowns can be used for teeth in the back of the mouth.

At the margin of any crown, bacteria can get in to cause a cavity. A benefit of a gold crown over porcelain is that the size of the margin (called the “discrepancy”) is much smaller with gold.

My patients with gold crowns have a discrepancy of about five microns. Porcelain crowns leave an open margin of about 200 microns that can be detected by a sharp instrument. The smaller the discrepancy, the less space dental cement is needed to fill and the less chance you’ll get a bacterial infection.

Another reason I recommend gold crowns when possible is that porcelain doesn’t wear at all over time—but your teeth do. Dental gold, though, wears at the same rate as your teeth: around 10 microns per year.

The wear rate of your dental crown matters for two reasons. One, when your living teeth wear down but your crown does not, as with porcelain, the margin between tooth and crown will continue to increase. The larger your margin, the more space bacteria have to get in and cause further infection or decay.

Two, your bite naturally changes over time as your teeth wear. A crown which doesn’t wear will disrupt your bite as your actual teeth change in size—think of how it might feel to have one longer tooth when you bite down.

If your child needs a crown, your dentist may recommend another type of metal crown: stainless steel. Stainless steel crowns can be made to fit baby teeth and easily come off with the tooth when it falls out.

I understand that many people don’t want gold crowns, or other metal crowns, for cosmetic reasons. Many dentists don’t even offer gold crown options!

Porcelain isn’t toxic, unlike common filling materials such as amalgam (mercury). It may cause some issues decades down the road as the tooth it’s on wears down, but it’s not a dangerous option by any means.

What issues could you eventually have with porcelain crowns? The major drawback of porcelain is that, unlike gold, it doesn’t wear down. As I explained above, this may open the door for further tooth decay as your margin expands to allow bacteria inside.

You’ll also need to replace a porcelain crown within 15-20 years. It may sound like a long time, but gold crowns last much longer (between 30-50 years). Especially if you’re looking at a dental crown for a back tooth, go with gold if you can to avoid having to replace it down the road.

Porcelain-fused-to-metal crowns may have a dark line around the gumline of the tooth they cover. These less expensive alternatives to porcelain crowns may not be as preferable from a cosmetic standpoint.

If you opt for a gold crown, you’ll need to find someone who specializes in dental gold. It’s actually easier to manipulate than porcelain but does require a different technique.

How much does a dental crown cost, and is there an alternative?

A good quality porcelain crown will probably run between $900-1600. A gold crown tooth adding about $100 to the total cost.

The price of a crown varies by location. Seeing a general dentist versus a prosthodontist who specializes in these sorts of items will also impact cost (general dentist crowns are less expensive).

Quality matters here. Some dentists will charge less ($600-800) but get crowns from labs overseas from places like the Philippines. Unfortunately, this often results in contaminated products. Many of these factories also use generic materials rather than brand-name ones that have consistent results over years.

Ask your dentist or dental assistant for the brand name of the dental crown you’ll be getting (I personally use EMax and Bruxer). A good lab will provide that name and you can use it to do your own quality research online.

Bonus: brand names keep their colors the same over time, unlike generic varieties. I keep records of patients’ crown colors and can duplicate them over time.

The cost of a crown is the number one question I get from patients, and I know it’s an important one to answer. Even though the dollar amounts may seem large, a crown is vital to your dental and oral health. If you need a crown, you risk long-term damage or infection the longer you wait to get it.

After a root canal, I tell patients that they can wait up to six months to get a crown if they’re eating well and following good hygiene. More than that is not a good idea.

Can I just wear my temporary crown forever?

When you go to the dentist for a first crown appointment, your dental assistant will fit a temporary crown. You’ll wear it about two weeks, until the permanent crown has been manufactured and delivered. Depending on the quality, some temporary crowns could be worn for several months or longer.

However, no, you shouldn’t just settle for the temporary crown.

Why? Because of the type of materials used for temporary dental crowns, they will change shape. This allows for shifting of other teeth, collect bacteria, and even possibly allow gum bleeding or inflammation.

My crown fell off. Do I have to go back to the dentist or can I glue it back on myself?

It happens—crowns sometimes don’t stay on, and it’s not always possible to see the dentist within the first few hours. While there is a good temporary solution, you will still need to see your dentist to have the dental crown permanently reattached.

The best thing to do for a crown that falls off is to buy over-the-counter temporary dental cement, available at most drugstores or online. These bonding agents are temporary, but can definitely hold on a crown for a few days or up to a week before you can get into your dentist.

The worst thing to do (which is, unfortunately, incredibly common) is to use Super Glue. I see it often… A wife keeps glue in her purse for the occasional need, and her husband will rifle through to find it and glue a crown back on his tooth to save a costly trip to the dentist.

I once had a patient share with me that Super Glue was better than Krazy Glue for putting a crown back on. Obviously, he’s had some experience differentiating between the two.

I’ve had patients try Super Glue, emery boards, and even power tools to reattach their crowns. As amusing as it sounds, using any of these methods to reattach a crown will lead to much more expensive dental work.

It is true that cyanoacrylate, the generic name for Super Glue and Krazy Glue, is used by physicians for wound repair. In fact, cyanoacrylate bonds very well to surfaces that are moist and non-porous.

Sounds perfect for that dental crown that keeps coming out, right?

Unfortunately, that notion is wrong and here’s why: The crown is a non-porous surface and can be moistened, but the tooth, despite being very moist, is also very porous. Therefore, the adhesion (glueing) between the two is negligible and will not last.

The real danger is forcing the cyanoacrylate down and killing the inside of the tooth. This will ultimately lead to the need for a root canal or even the loss of the tooth due to resorption. It’s also toxic to the gums and can cause necrosis, or tissue death.

The Bottom Line: Don’t use anything but temporary dental cement to reattach a crown that falls off. Then, get to your dentist as soon as possible to have it reattached.

How does my crown stay on?

Did you know that your crown actually doesn’t stay in place because of adhesion (aka, glueing surfaces together)? Dental crowns remain in place for years by a process called mechanical retention.

Mechanical retention is best explained like this: Imagine placing an identical, straight drinking glass over another identical glass. Pick up the upper glass and the one below comes with it, and the two “stick” together as you lift the top glass.

Now, try that with two identical bowls stacked face down on top of each other. It’s impossible to pick the bottom bowl by lifting the one placed on top. This is a simple example to explain how mechanical retention works—and doesn’t work.

A dental crown is made to be at an angle of 3% or less to the tooth surface—more than that, and, like the bowl example above, you’ll find that nothing holds.

Correct mechanical retention allows a crown to stay on indefinitely, especially if you practice good dental hygiene and avoid the worst food for crowns.

The “glue” your dentist uses is luting cement, made from zinc oxide and eugenol. It simply prevents saliva from getting into the margin (the space between tooth and crown); It doesn’t hold the tooth to the crown.

Parallel walls make the difference—a crown with a huge taper (known as “teepee prep”) will fall off. You need near parallel walls on all four sides. I describe the way this looks like a mesa: a flat-topped hill.

Why would my crown fall off?

Once a dental crown starts moving, it breaks the cement and will fall off because it’s retained via friction, and movement disrupts the friction. So, if that crown keeps falling off, it’s not due to a lack of adhesion—it means your tooth underneath isn’t the right shape for mechanical retention.

Dentists don’t actually use glues; we use cement to prevent saliva from seeping between the crown and tooth. This prevents tooth decay.

The shape of the tooth underneath and the tightness of the fit keep the crown from falling off.

How can I prevent my crown from falling off?

Some of the ways to prevent a crown from falling off aren’t things you can control. For example, a car accident or other trauma can make you clench your teeth and jam them in such a way that mechanical retention is disrupted. Oral surgeons sometimes pop off fillings when they’re removing a nearby tooth. In addition, poorly made crowns don’t like to stay on forever.

However, there are steps you can take to prevent your dental crown from falling off, too. The most important of these is to avoid or very carefully eat sticky foods.

To illustrate this point, I should share that when I am removing a crown in my office, I use jujubes!

First, we soften a jujube in warm water. I place it over the crown, requesting the patient to bite down. Once the jujube cools, I instruct them to open again. This is the most effective (and inexpensive) way to remove a crown.

The same applies to a dental crown you may not want to remove. If you make a habit of eating sticky foods, you should be very cautious chewing with a tooth that has a crown.

Take good care of your teeth and crowns by:

  • Brushing and flossing properly
  • Eating a lot of plant-based, nutrient dense foods
  • Learning to breathe through your nose

The same things that are good for your teeth are usually good for your crowns.

Can I whiten my crown?

Porcelain crowns can’t be whitened because they aren’t living tissue. The good news is that they also can’t be stained like living teeth, either.

When you initially get a porcelain crown, your dentist and lab match your current tooth color (which, by the way, isn’t really “white”). However, this can become somewhat problematic if your teeth change color significantly over time.

If you want a whiter crown (or darker, in fact), the only solution is to go to the dentist for a new crown.

How long do crowns last?

Assuming the crown is properly done, a porcelain crown lasts 15-20 years, while a gold dental crown can make it 30-50 years.

You may need to have a crowns’ fit readjusted in that time if it falls off. Even the best porcelain crowns can’t last more than about two decades.

How do I best take care of my crown at first? What about as time goes on?

Many people have a misconception that crowns must be “babied” for the first several weeks (don’t chew on them, be super gentle with brushing, etc.).

While these tips are great for your temporary crown, they aren’t necessary once a permanent crown is attached.

In reality, what I tell my patients is this: Wait at least 60 minutes (I give them an exact time) before eating, brushing, or flossing. After that, your permanent crown will function like the rest of your teeth.

You would be surprised how many people want to go straight home and floss around the dental crown, but this doesn’t give dental cement a long enough time to set.

Over time is when porcelain crowns become more problematic because they wear at a different rate than the crown. Trauma, disease that increases inflammation, or a poorly balanced oral microbiome can also impact the fit of your crown.

If you begin to feel a crown shifting or experience pain in that tooth, visit your dentist to see if you need a replacement or reattachment.

What’s the difference between dental crowns and veneers? What about crowns and dental bridges?

Dental veneers only cover the front of your tooth, while crowns encase the entire tooth. Veneers are thinner than crowns and require less grinding down of the tooth to fit correctly.

Most of the time, people get dental veneers to improve the color or appearance of visible teeth. But veneers don’t actually protect your teeth the same way a dental crown does.

Dental bridges use a fully prosthetic tooth (or teeth) to fill in a gap between two existing teeth.

When you get a bridge, the teeth on either side of the gap must be covered with a crown. If either of those teeth are particularly small or weak, your dentist may opt to crown two teeth on the sides of where the prosthetic tooth/teeth go.

Final Thoughts on Dental Crowns

Dental crowns are used when the tooth surface is altered and where the inside of the tooth needs protection from infection and breakage. This happens in many cases including root canals, tooth breakage, large fillings, and more.

Children may need crowns to protect baby teeth if they have issues that prevent them from taking good care of their teeth. Baby teeth may also need crowns to protect a cavity too large for a filling, until the adult tooth comes in.

Contrary to popular belief, crowns and root canals don’t always go hand-in-hand. Just because you need a crown does not necessarily mean you also need a root canal.

Unlike living teeth, a dental crown is an inanimate object used to protect living teeth. The way you care for them is essentially the same as teeth—by brushing, flossing, etc. But crowns can’t be whitened, mineralized, or stained.

Well-made crowns can last for up to 50 years, in the case of gold, or up to 20 years with porcelain. Grinding teeth (bruxism) shouldn’t cause a good crown to fall off. But trauma, eating sticky foods, and other experiences may loosen the mechanical retention holding your crown in place.

If your dental crown falls off, schedule an appointment with your dentist immediately. You can purchase dental cement over the counter that will temporarily hold the crown on until your dentist can reattach it for you.

Do not use Super Glue or any other adhesives to reattach your crown on your own. These will lead to much more serious problems down the road because of toxicity and actually don’t work long-term.

  1. Hello, and thank you for this information on how to properly deal with a crown that has fallen out. Many people have dental crowns, and depending on the type sometime they can fall out. I think it’s important to always seek the help of professionals when dealing with this type of thing to make sure the job is done right and effectively.

    • My crown fell out and I bought an emergency repair kit as I was going on hols next day 3 years later its still in place with no problem whatsoever

      • what did you use from the emergency repair kit that worked? i need this answer asap as im going on a trip in 2 days too lol

        • What repair kit did you use. I am in the same boat as you!

      • Joe Worrell says:

        Where do you buy an emergency repair kit.

        • where did you purchase the emergency kit for your crowns asi have to go to work tomorrow and 2 crowns came out last night thenks, carol sullivan

      • May I ask what cement composition you used and brand, and how you did it?

      • Mine has falling pout where did you get the repair kit from x

  2. Irena Ryans says:

    Thanks for the information. My brother has been wondering if he can glue his crown back on. After reading this, it seems like that would definitely not be a wise idea! Just like Fitz said, it’s absolutely crucial that you seek the help of a professional to do the job. That’s definitely the safest way.

    • Hey — actually maybe you talked to someone who wasn’t as good at research. I know someone who went online, studied for a few nights, watched a few youtube procedures, and then went online and bought the stuff dentists use from a site. Not sure what he bought or watched, but he claims he recemented his crown better than his own dentists did using something called “etching” using the same exact ingredients he said are currently used in a dental office. He did something else, but the gist of it is, people who are intelligent and do proper research aren’t using super glue. Because I just researched a bit myself and found people are not all idiots, and as someone whose veneer keeps popping off, I find this encouraging. What is disappointing is JUST how many dentists seem to think we are all idiots using superglue.

      • Stephanie says:

        You sound very defensive and I am not an idiot but very thankful that the dentist said NOT TO USE SUPER GLUE BECAUSE IT CAN KILL YOUR TEETH! Pretty sad that the dentist offered a very neutral honest post and you have to cut him down for some weird reason beyond any of our understanding. Very interesting.

  3. Virginia Davis says:

    Thanks for the information. My mom’s crown fell off one summer, and I am glad we didn’t think of trying to fix it ourselves. After watching, “Castaway” I have not really been a fan of DIY dentistry. After reading this, I will be sure to get my dental crowns repaired by a professional.

    • Mark Burhenne DDS says:

      Virginia, thanks! I had forgotten about that Castaway scene…great reminder of the problems with DIY dentistry.

  4. Sam Fisher says:

    I don’t know about you guys but I wouldn’t feel completely comfortable about putting super glue in my mouth. It may work fine without repercussions but what if you were to mess up or not put the crown back exactly in place? Yes people are doing these things at home, but it would be better if they had them done at a dental office. At the dentist, they would be able to put the crown back exactly where it is supposed to be with a minimal margin for error.

  5. So as crazy as it sounds about super glue and your crown… here is my current story. At age 11 I fell down my stairs and hit my face slap down on the concrete basement floor. My two front teeth were done. It was right before Christmas so I asked Santa for “my two front teeth” I got them. Mom took me to get temporaries until the final crowns were installed. (Had two permanent crowns since then, and had to replace them once each since) Fast forward to last year. Fell down and hit my face again. This time one of the perm crowns broke off. So I was left with a stub on my front tooth. I work in retail so I had to have a smile. I grabbed the pieces of my tooth and got a tube of superglue out and proceeded to glue it back. This was the most embarrassing moment of my life. I was able to save the rest of the crown and take it to my dentist. They used some cement and color and fixed it for me the best they could till I could get another crown. So it has worked for me for a few months, but I can’t bite on anything and it becomes loose after two weeks and I have to re-superglue it. I am embarrassed to tell this story, but I am sure their are others also dealing with it too. So felt like I needed to share.

  6. What about the use of actual dental cement. Can one buy that somewhere? I have a real problem with tooth grinding and I often grind the thing right out of my mouth. then another trip back to the dentist where he turns around and glues back in

  7. Nancy Green says:

    I have a crow that comes off several times a day. I use Fix-O-Dent to hold it the best I can. My problem is I’m totally bed fast and live in an Assisted Living Home. To go to the dentist would involve going In an ambulance which cost me $200.00 round trip and I don’t think the gurney would even go past the waiting room and there’s no way I could get in the dental chair. Please I need to know what I should do. I’m only 62 years old and have MAJOR health issues. THANK YOU!

    • Alan Spencer says:

      Dentek Cap and Crown Cement. £7.29 FROM ANY LARGE PHARMACY.

  10. EMORY LANKFORD says:

    Those who commented on the article by repeating “go to the dentist” are missing the point entirely. Most assuredly, everyone who needs to have a crown replaced or repositioned would make a bee line to their dentist if money were not an issue. To respond with “go to the dentist” is cavalier and insensitive to those in less, or unfortunate, financial circumstances. I often hear others being advised to seek reduced fee or free dental care, but not once have I ever seen a practicing dentist offer either. Walk into a dentist office with a toothache or other oral emergency, you will be shown the door if you do not have the funds to cover all charges in full. While makeshift methods such as superglue may not be the best answer to solve a loose crown, it does work. When someone has no other options, then they do whatever is necessary to achieve the desired result.

    • Well said my sentiments entirely, there are a lot of people to who can’t afford a dentist.

    • Tiffany Kathryn Lindley says:

      Thank you for this!! Your Empathy and understanding as well as your eloquence are a rare thing nowadays … I wish more people had your grasp of how real people live

  11. K Campbelli says:

    You absolutely can buy the same adhesive and clean /glue your crown back on.
    Just Google dental adhesive and fix it yourself. The dentist won’t get a new yacht this year…..

    • Dr. Mark Burhenne says:

      Be aware that the dental cements available to the public are temporary adhesives only as they are soluble. They slowly dissolve away leaving the tooth vulnerable to decay, a root canal and eventual loss.

      I don’t charge for recementations of crowns and inlays I placed, as it does not happen often. Many dentist to the same and stand by their work.

      I hope this information is helpful. Permanent cement is only available to those that have a dental license, and it’s not the same stuff that you see available on line and in pharmacies.

      • Tiffany Kathryn Lindley says:

        I wish you lived close to me because I have been victimized by by very unethical practitioners… The last one shortened by front teeth so much, for ‘cosmetic’ reasons, that I not have really bad TMI. Not to mention the realigned bite caused my dental implant to move from side to side, which I don’t think they were designed for. One is now lose, which brings me to this forum… I have another crown on a root canal that keeps popping out.. One dentist kept recementing and charged me $170 a pop, the other said there was decay and the root canal needed to come o myselfut and an implant be placed… One said there was decay, the other said the needed veneers… So, I went to another one for a re-cement, when the tech left I studied everything they used, and while she was working I studied everything they did… I ordered KETAC CEM plus luting cement.. and I will do it myself…I passed all 5 tests on the Mensa website (thought they would give me a job, hehe) so I think I have the brain power to do it… My horse got lacerated on barbed wire and I actually numbed and sutured the area myself after a Vet quoted 5k for a 4 inch cut… He’s jumping 4 feet now and there isn’t even a scar

        • Mitch Middleton says:

          Thank you I found it at Net32, I will give it a try.

      • Thanks for the info. I would be greatly appreciative if you could give me an advice. 10 years ago my front tooth broke half, so I got a crown for $3000. After ten years the crown came off. The crown has a metallic pin protruding out of it which goes into a hole in the half broken tooth. I took it back to the same dentist and he has re-cemented it. The crown got loose again after few months. I have gone back to the same dentist and one other dentist but they would not recement it. They told me that I need an implant. well, I cannot afford an implant and but they just told me to recement it yourself. I have asked what type to cement to use but they did not tell me, just told me to buy anything from the market. One just said to use ‘Speed Cement’ but there are several different types coming up on Google. Could you please tell me what to do or what is the specific type of cement I can use. Thanks.

      • The crown is made of porcelain.

    • If your crown came out and you replace with any type of glue, it will take up space. When it does, it will unnaturally hit the apposing tooth. My dentist ground down the tooth surface reducing the contact area.

      • Tiffany Kathryn Lindley says:

        If you are sick of money grubing dentists who let their techs do all the work… order the Luting cement online Ketac Cem plus luting cement… do it yourself… it is not like you are drilling

  12. I had a crown fitted one year ago. I told the dentist that I couldn’t close my mouth properly as there seemed to be a lumpy piece on the back of the crown which went up onto the start of roof of my mouth. It didn’t seem right she told me it would be all right and it would go away soon. It is still there but the strange thing is the sides of the back of the cap seem to be dissolving and I can taste a metalic taste on my tongue and it looks like the top of the tooth at the back is going back. I have never had a problem with my teeth and I am lucky to never had a filling in my 51 years. all my teeth look clean front and back but now I’m concerned. How do I go about it, I don’t want to be fobbed off as she did with the clump at the back of my tooth.

  13. Howdy crown restorers…

    If your fallen off crown has reveled a abatement that is in good order, utilize a friction mechanism re-attachment method.

    I used wax paper by trying different layer-thicknesses. Line the crown with the appropriate thickness for your situation. Heat the wax-paper with a blow dryer and let it conform with the inside walls of the crown. Set it on the abatement by biting down until you feel you have the ideal forceful attachment effort. You will know and try different thicknesses.

    My third time was a charm. Seven months and two weeks has passed with my crown in place…
    Ordinary baking wax paper has worked most excellently for me.

    No worries about the hang over of a wee bit of wax paper around the abatement and gum transition. Within a few regular brushing cycles and dental flosses it will dis-appear.

    Your gum, tooth, and crown points are sealed from bacterial agents and your pocket book is buffered from the mouth zombies…

    I’m really shocked that people would try gluing their dental crowns back on. It kind of makes sense but is not anything I would ever want to try. I am further convinced that I shouldn’t by your post. I definitely don’t want to cause irreparable damage to my teeth. It just means more dental work. Anyway, thanks for your post and explaining how dental crowns are held on through mechanical retention. I had no idea this was the case.

  15. You can glue it back in but not with super glue ‘ it does not last. Look on amerzon you will find proper glue.

  16. I had a crown that somehow got an abscess. I knew it’d need a root canal, and quite frankly, i expect some long term effects until I can afford to go to a dentist (no insurance). The pain was unbearable. Eventually, the crown broke off from the root, (solid on the inside) and now i have no pain. I use super glue to get it back in and it holds up pretty well. It’s certainly not a permanent solution, as i am still searching for FT work with dental… but.. a root canal will cost me too much.

    Hi all I recently had an implant crown come off, and had it re fitted by the dentist, have to say I am not impressed, took over an hour of faffing around and negative comments, I will be getting some dental cement ready to DIY if it comes off again, which I am sure it will, the original implants have lasted more than 9 years with no problem till now, I really do not expect this repair to last that long, I might add that I am a very capable self healer, for instance I fell years ago and was wearing “Dealer boots” the left boot was torn off and my for was at 90% to the left of where it should have been, I straight away pulled it back to where it should be, (re locating the joints to where they should be) in was immensely painful, and stared to swell, paid a visit to A & E where they X rayed it and pronounced all was in order, I had difficulty walking for a few months but now years later I would not know I had done it, the point is if something gets dislocated the sooner it gets put back the better, had I waited for the Hospital to sort it, it would have een far worse, Rick

    My boyfriend has a bridge consisting of three teeth, tooth broke that was holding in his bridge, can he use dental cement to glue the bridge back on to the tooth that is broken? A root canal was done years ago on the tooth that broke, which is holding the bridge to the other two teeth.

    • I had to have what is called a post and coil on the tooth that broke and the bridge was reattached to that. Not a do it yourself job. Sorry but sounds like a trip to Dr. $$$$$$.

  19. I just want a temp fix until I can get to the dentist on Monday ! But I don’t want to make his job any harder by putting some product on my tooth ? Will it be ok for s tom fix ?

    • What did you use I’m desperate will see the orthodontist on Monday but it’s friday night

  20. Will it be ok for a temp fix ?

  21. James Barnes says:

    Had crown completed has made Five trips back to dentist since he made the crown because it came off had some for twenty years still on but one with post does not hold

    • same here I have had crowns for over 30yrs but this one i had before xmas has come out 4 times now and is really begining to annoy me it has just come out again eating ice cream I could cry 4 times in 5 months its not good enough

      • Daniel E Keith says:

        @debbie Same. Have several crowns that I’ve had thirty years, no problems. But the temp crowns I’ve gotten this year, from a dental school doing the work, all come off anywhere from a day to a week after being put in. Then I have to wait three to four weeks till the perm crown is put in. At least the four crowns they put in this last year are still holding strong so far.

  22. Debra-ann Shrives says:

    My tooth came loose from my dentures so I glued it but it’s in the wrong place, how can I get it loose ?Help thanks Debbie.

  23. I have a metal back porcelain bridge over my 4 upper front teeth. Those teeth were prepared for the bridge by the dentist and now are ground down nubs. The bridge never has stayed on longer than 30 or so days and this has been going on for over a year.

    I have told the dentist that I believe one of 2 things has happened. The bridge never fit correctly
    ( either the fault of the manufacturer or the dentist`s mold was off) or the teeth are were ground down to much.

    Can metal be added to the inside of the bridge to create a tighter fit and increase the chances of the crown staying in?

    I’m going to keep googling! Of course having everything handled by a well trained and properly equipped professional would generally be best, but this feels like a professional car driver telling us stories about some accidents and drunk drivers and concluding that we all better stay home until a proper chauffeur comes to drive us around in our own car. I’ve heard of people drilling their own teeth and the does sound crazy to me… but I’m here because a temporary crown (awaiting the arrival of the permanent one) came off and my dentist said “tomorrow” then the next day said “tomorrow” again so I used super glue. When I texted to say I thought it would be okay until next week (for a mutually convenient appointment time) the message from them was that I should not do that… when I said I already had they spoke of how inappropriate, poisonous, damaging it might be. People die in car accidents every day and probably people mis-glue themselves with some frequency, but nothing I’ve read here makes it sound like super (or “crazy”) glue would be bad to use TEMPORARILY on a tooth that is already root-canal-ed. I can see where trying to use it long term would invite decay issues. Back when “krazy” glue was new, a consumer reporter used two panes of glass (as the dentist in this article described) but she declared that the “trick” of the krazy glue was that it acted like the water between two panes of glass (which will loose their suction when the water between the panes dries out… so, at least it seems to me… filling the tiny voids that allow a crown to slip off its post is basically exactly the kind of job that krazy glue was made for!

  25. I’ve been to the dentist twice in as many days. They put a temporary crown on yesterday, and I popped out last night. I had it placed again today by the dentist. It’s already come out again. They suggested I get an over the counter dental bond or simply use toothpaste. I have to wait two weeks for the “permanent” crown. I’m not happy. Any input?

  26. Henrietta says:

    Is it possible for dentist to bond one false upper tooth to teeth on either side without using a bridge , i have a temporary plate , hate it but also dont want a bridge , i dont have even have a bit of tooth in cavity

  27. A few years back, I had my four lower front teeth in a row crowned, last year one of the crowns fell off and I had it reglued at the dentist, this cost me $250.00. I had another of the 4 crowns fall off today. Called the dentist, went right down and had it replied to the tune of $290.00. I still have two out of the four crowns in place with the original glue…just waiting. These prices are ridiculous to reglue a crown but when it falls off on a front tooth, what else can you do? THIS is the reason people want to know where they can buy a glue that will hold, I’m looking for one now too. Does anyone know where to get the good glue?

    • Tiffany K Lindley says:

      Do not give that robber of a dentist any more money!! order Ketac Cem plus luting cement online… It is what dentists use, I know cause I went through all the stuff they used when the tech left the room… I ordered some online and will use it… it’s gluing one shape onto another. If you can craft, you can do it

  28. Should I just take the teeth out? They are three front teeth. I have temporary crowns – do i leave them out while I sleep until I can see the dentist?

  29. nick varg says:

    Why quality dental cement is not available for a public?
    I would like to charge the dentist every time I go for re cementing loose things…

  30. Angela Andreoli says:

    To Lynne:
    I am appalled that your dentist would put you off day after day to get a temp crown cemented in, let alone charge you! I love Dental Care in Vineland NJ. They are an awesome, caring and committed team. Not only did they squeezed me in the next day, no charge for cementing the temp. They are replacing the permanent one for free cause it was loose before it was a year old! How is that for customer service !

  31. Hobie,

    I drive a white van and have 4 crowns recently fitted, they also came off so I tried your swishing method to save a bit of time, lo and behold it has stuck all my mouth together and I am now in A&E slightly embarrassed awaiting a Doctor, the triage nurses are smirking away to themselves for some reason, I just feel a bit daft and am in a hell of a lot of pain!! In fact it’s a good job I can type this as I certainly can’t talk, and can’t drink this glass of milk? Impossible to swallow!

    So please don’t make my mistake people and glue them in one at a time!



  32. My crown that was fixed back in India has just fallen off. I stay in Dallas. May I know the cost to get it re fixed?
    Thank you

    • Bessie Lou says:

      I am in Dallas also and need the same information. Thanks.

    I have a slightly different problem. My temp crown came off. It’s three more weeks till the permanent gold crown will be ready and installed. I’m having dental work done at a Dental school and it’s a 2 1/2 hour drive away. So I’d like to know if there’s a temp glue I can use to save me the trip in the mean time. BTW, the Dental school is in Indianapolis, IN. and the total cost for the gold crown is under $600. That’s for all the prep and everything. It takes three visits to do each crown. Gas to get there and back is around $40 for me, so with gas and the schools charge, $720 for a gold crown sounds pretty nice considering the last time I had a full time dentist do a crown, twenty years ago, it cost me $600. I’ve seen some of the posters here say their full time dentists charged them upwards of $3000 for a crown! 0_o. The school has been great, but at the second visit where they put on the temp crown, they have always come off before the final crown is ready. One came off during my first meal. Another lasted a week, this one only lasted two days. It’s intact, so wondering if I can reattach it myself?

  34. Daniel E Keith says:

    @Hobie I’m surprised your post made it past the moderators! Swish superglue? Are you insane? You are most likely a Troll. Superglue bonds INSTANTLY.

  35. Why is it after paying a huge amount of money we have to fix it ourselves. A lot of what you read blames the patient. I’m going on my third temp crown. The first 2 cracked off at the same spot and was so sharp it scraped the back of my tongue and made it sore.

  36. Greg Ochoorena says:

    wasn’t a form of Krazy glue invented for you teeth

  37. Tyler Johnson says:

    That’s good to know that you can take care of a permanent crown the same way you would the rest of your teeth. I wouldn’t want to have to spend extra time taking care of a crown for the rest of my life. I can see why you would need to take care of a temporary one, but I’m glad that a normal one will be just fine with normal brushing and flossing.

  38. Gerry Shaver says:

    Great dental crown information! Thanks. I have a question regarding experiencing pain under a new crown:
    I had a tooth that was resorbing and was holding one end of a bridge. This resulted in pulling that tooth, getting two implants (one to replace the resorbing tooth and the other to fill in the empty space beside that tooth. I then had to re-crown the back tooth that was holding the other end of the bridge. At the end of this process, it took 4 attempts back and forth with lab “tweeking” the crown and over a period of 4 months to get a crown that would fit the back tooth. Over that time I had two temporary crowns put on that tooth and had no pain or discomfort. When the dentist finally placed the permanent crown on that tooth he polished the tooth and I immediately felt pain at the spot he polished and he stopped. He then cemented the permanent crown onto the tooth. I called a few weeks following to tell him I still had the discomfort and later scheduled a followup dental appointment a month after that he again could not tell me why I still had the discomfort. This discomfort is an ache and has some sensitivity to cold but not hot. When I floss between the implant and the crowned tooth I can really feel a sensitive spot where these two teeth meet which is the top of the teeth. No excruciating pain but as I am typing this I can “feel” the discomfort in the crowned tooth. Sometimes I don’t feel it but I do everyday and I know for sure something is not right. What advice can you give me as my next step at finding the source of the discomfort/pain ? Thank you. I live near Wilmington, NC and am looking for a new dentist. ay suggestions?

      Find a good functional dentist in your area! I have an article with tips if you don’t already have one in mind.

  39. I need some crowns and was hoping to get porcelain. Are porcelain and ceramic dental crowns made of the same thing? Then I read that porcelain or ceramic dental crowns can contain alumina and also could contain uranium oxide or toxins from depleted uranium. I had felt so confident about the porcelain or ceramic crowns being biocompatible and now I don’t know what to do. Is this a cause for concern. If so what should I have my crowns made of that are safe?
