Why do I have sensitive teeth? Causes, Remedies & When to Visit the Dentist

Updated on
sensitive teeth

When you have sensitive teeth, even the most mundane activities can cause excruciating pain.

Whether it’s sipping tea, eating dinner, or walking outside in chilly weather, you might notice a toothache start when your teeth are exposed to heat, cold, or even certain foods and beverages.

The sensitivity of teeth to these stimuli is called dentin hypersensitivity.

In this article, I’ll help you figure out the root cause of your sensitivity, determine the best treatment options, and help you prevent sensitive teeth in the future.

Why are sensitive teeth so painful?

Teeth are covered by an outer layer of enamel that protects the softer, inner layer of dentin. The gums also assist in this protection by covering the dentin of your teeth’s roots.

When enamel is compromised, dentin is exposed and pain is likely to follow.

Cavities, cracked teeth, receding gums, and enamel or root erosion are common causes of sensitive teeth because they degrade enamel.

Dentin is directly connected to the nerve that triggers tooth pain, so when cold air, hot liquids, or other external factors reach the dentin, it can be agonizing.

That’s what tooth sensitivity means.

Before we look at how you can get relief from painful tooth sensitivity, we need to look at why teeth might hurt in the first place.

Causes of Sensitive Teeth

There are many causes of sensitive teeth—some of which can be treated at home, and others that require the care of a dentist.

One easy way to figure out if you need to visit the dentist or try home remedies for tooth nerve pain is this…Is the pain throughout your entire mouth, or is it more local to one tooth (or a few)?

In general, pain or sensitivity that impacts your whole mouth but is not severe is typically caused by factors you can change. Think: generally achy teeth or pain that occurs on both sides of the mouth.

Perhaps you’ve been eating too many acidic foods or grinding your teeth at night, for example.

On the other hand, pain or sensitivity that impacts only one or two teeth, or that is very severe, should be diagnosed by a dental professional. It may require one of several types of procedures to treat.

Before we get to treatment options, let’s take a close look at the different types of teeth sensitivity and what can cause them.

Regional Tooth Pain (One or Two Teeth)

For either severe pain or pain in one or two teeth, your dentist will likely use a process called differential diagnosis to determine the source of your sensitive teeth.

X-rays and visual exams are part of the process, too, but they may not immediately reveal what’s causing your pain when used alone.

Differential diagnosis simply means that your dentist will ask you lots of questions about your pain and dental habits. Then, s/he’ll use the process of elimination to identify the single source—or tooth—that’s causing the pain.

If your dentist uses differential diagnosis to address your sensitive teeth, it’s important that you provide as much information as possible.

What are your symptoms? Have your eating habits changed? Did you recently switch toothbrushes or start using an at-home whitening system like Crest whitestrips?

Sometimes, issues like a deep cavity can “refer” pain. This means the dentin hypersensitivity may not be confined to the tooth with the cavity and could actually present in nearby teeth.

However, even in those cases, the referred pain will be on one side of the mouth. It can even affect the opposing arch on the same side, like the upper arch for a lower tooth cavity.

When tooth sensitivity is localized, it be a result of one of the following:

1. A Cracked Tooth

These can become filled with bacteria from plaque (a microbial biofilm found on the surface of the tooth) that cause inflammation in the pulp of the tooth. In more severe cases, it may lead to abscess and infection.

2. Cavities

Cavities, or dental caries, occur when enamel has become demineralized, exposing dentin. Once the dentin has been exposed, you will probably experience pain in the affected tooth.

It’s also important to note that, at this point, you won’t be able to reverse the cavity at home and will need to have it filled.

3. Tooth Abscess

An infection of the gum or tooth can eat away at enamel, too. Eventually, this can create an abscess that must be removed in order to stop the pain or sensitivity it causes.

Tooth infection symptoms that could point to an abscess also include swollen jaws, swollen lymph nodes, fever, bad breath, and draining sores.

Abscess pain is the kind that puts you on your knees, so if your teeth hurt so much it’s unbearable, this is one major reason to look for.

4. Gingivitis

Gingivitis often causes inflammation near the gum line, close to teeth. This can cause gum pain to be referred through the root of a single tooth or several teeth at once.

Chronic gingivitis might also trigger pain or sensitive teeth because it can cause gum recession.

When gums are recessed, food impaction, like getting a tiny piece of popcorn stuck between your gums and teeth, is more likely to occur. This can cause localized or global pain—your gums hurt and your teeth hurt.

5. Dental Procedures

Due to their invasive nature, dental procedures can cause some short-term pain to the teeth that were worked. Your dentist can help you determine whether you’re experiencing normal pain after a dental visit as you heal, or if there is a problem related to the procedure that needs to be fixed.

Global Tooth Pain (Pain Everywhere)

Pain throughout the entire mouth is referred to by many names, like:

  • Non-localized teeth sensitivity
  • Universal pain
  • Bilateral pain
  • Global pain

If you’re experiencing sensitivity in all or lots of your teeth on both sides of your mouth, I have great news for you! Your sensitivity is probably caused by an external issue like diet, illness, or change in lifestyle habits.

That means you can likely fix it without having to go to the dentist.

Here are some of the causes of global teeth sensitivity I’ve seen in my patients:

1. Eating More Acidic Foods

Have you ever discovered a new favorite food and wanted to eat it nearly every day? If that food is high in acid—which can damage enamel—your teeth could become newly sensitive in a matter of days.

2. Teeth Whitening

The ingredients in teeth whitening products like whitestrips are acidic and can break down enamel easily.

Sensitive teeth caused by whitening products should feel better in about 3-5 days after you stop using the product.

3. Sinus Infection

When you have a sinus infection, the inflammation from the infection is located very close to the nerves that cause tooth pain.

This type of pain is intermittent and based on position (meaning it can intensify if you’re sitting, lying down, etc.). It can also move to many different areas of the upper teeth.

4. Poor Brushing Technique

Over-brushing can cause surface enamel to wear down over time, which can lead to sensitivity to sugary, hot, or cold foods. For a tooth sensitive to cold, the first thing to do is be gentler while brushing your teeth.

This could be caused by brushing too hard, brushing too much, or using a brush with bristles that are too hard.

5. Receding Gums

This irreversible condition can expose areas of teeth with very thin enamel. As recession gets worse, even the slightest provocation or tooth decay can cause severe tooth pain.

Causes of gum recession can include these (and more):

  • Gingivitis
  • Over-brushing
  • Eating crusty and firm foods like popcorn or sourdough bread
  • Systemic problems, such as diabetes and heart disease

You’re more likely to see gum recession as you age. That’s why, as you get older, your dentist should measure the length of your exposed teeth at each visit.

Unlike other causes of universal tooth pain, you will need to work with your dentist to slow, stop, and/or treat gum recession.

6. Plaque Buildup

Plaque and calculus can eventually break down the surface of teeth through demineralization. These are the buildups that your hygienist is most skilled at getting rid of.

After calculus is removed, the portion of the tooth now exposed is likely to be more sensitive to sugar, hot, or cold because it’s demineralized. This is one reason some people have toothaches after a full scaling and root planing (also called a deep teeth cleaning).

7. Long-Term Use of Mouthwash

Most over-the-counter mouthwashes are very acidic. If dentin is exposed to acids on a regular basis, the acids can wear away enamel, exposing dentin, and also make existing tooth sensitivity worse.

There are neutral or alkaline pH mouthwashes available that might be a better option, or you can make your own DIY mouthwash.

8. Dental Procedures

As I mentioned above, you may have tooth sensitivity after any kind of dental procedure. Even a cleaning can cause pain for some people, especially if they also have other factors that can contribute to sensitivity.

A high filling or crown can also cause tooth pain in the form of cold sensitivity, which would indicate the need for a follow-up visit.

9. Chronic Inflammation

Diabetics with high blood sugar can experience inflammation in the ligaments that connect teeth in the bone socket, causing pain during chewing. While most often related to diabetes, this condition can also occur with other forms of chronic inflammation.

Sensitive teeth and the associated pain can be a result of some, or all, of the causes above. It’s also important to mention that your sensitivity may be caused by unique factors that I haven’t mentioned.

For example, abruptly changing climates from cold to hot and back to cold can foster a sinus infection. Combine that with a diet filled with more acidic foods than normal, and you may find yourself arriving home from a tropical vacation with tingling, aching teeth.

Grinding and Sensitive Teeth

One of the most common causes of sensitive teeth (as well as mouth and jaw pain) is nighttime grinding, otherwise known as bruxism.

I’ve written about this topic at great length (including in this article explaining why you probably grind your teeth in the first place), but the most important thing to know is this:

Grinding exerts tremendous vertical forces upon the teeth (anywhere from 600 to 750 pounds per square inch, depending on your gender and weight) that can lead to teeth sensitivity, gum recession, fractured teeth, and even eventual tooth loss.

In most cases, grinding is the result of a closed airway.

Basically, grinding and the thrusting of your jaw occurs as a bodily reflex to save you from a collapsing airway.

I used to prescribe night guards for grinding, but I don’t anymore, as it’s more important to address the true causes of grinding instead of just minimizing its consequences.

While many used to think grinding was caused by stress, it turns out that sleep apnea is more often the cause.

So if your dentist discovers that grinding is the cause of your sensitive teeth, determine why you’re grinding and treat the bruxism as you treat the sensitivity.

How to treat sensitive teeth: what can you do?

Due to the number of possible causes that may be causing sensitive teeth, treatment methods don’t always fit into a single category. However, following are some of the possible methods you and your dentist may discuss for treating tooth pain.

1. Damaged Tooth Repair

Particularly for localized, single-tooth sensitivity, there may be damage to a tooth or teeth that requires dental intervention.

A cracked tooth, for example, must be repaired with a crown and/or root canal (in conjunction with a crown) to protect the sensitive dentin.

If you have a cavity that has broken through to the dentin, you’ll need to discuss options for removing the diseased tissue via filling, root canal, or extraction.

2. Abscess Removal

If an abscessed tooth is causing your sensitive teeth, your dentist may need to drain it to relieve the pressure. Other treatments for abscessed teeth and related infections sometimes include root canals, extraction, and antibiotics.

3. Treating Gum Disease

If severe gingivitis or receding gums are causing your pain, you may need to visit your dentist for thorough cleaning and, in some cases, surgery.

Following the procedure, symptoms including inflammation should go away in a matter of a few weeks.

If your gum disease is mild-to-moderate, you may be able to reverse the condition at home by making some key lifestyle changes.

Adopting a paleo-friendly diet that is full of nutrient-dense, inflammation-fighting foods and free of sugars, grains, and processed food is the first step. Focus on grass-fed/pastured meats, healthy fats, and green veggies.

Other home remedies for gingivitis include:

Although food impaction isn’t technically considered gum disease, it will cause gum disease over time. And in the short-term, it can cause a lot of pain.

A small crevice between teeth or between a tooth and a nearby crown or filling can get filled with tiny food particles that cause very acute pain. In these cases, your dentist can clear away the food impaction and that may alleviate pain immediately.

If you think your pain or sensitivity is a result of food impaction, you can first try using knotted floss at home to clear it.

Interestingly, the mid-course of an Invisalign treatment can be a prime time for food impaction as teeth are pulled apart before being realigned.

4. Correction of Failed Dental Procedures

Before any dental procedure, your dentist should let you know about the type of pain you should experience, if any, as a result of the procedure and healing process.

If you experience pain for an extended period of time, or if your pain is more severe than normal recovery pain, your dentist may need to do a follow-up procedure to correct additional issues.

One common example of this, mentioned above, is a crown or filling that’s too high and leads to cold sensitivity. Correction of this issue takes only a few minutes at the dentist.

5. Dietary Changes

Both to prevent and treat tooth sensitivity, you may need to make changes to your diet.

Acidic foods and drinks (citrus fruits, soy sauce, soda, and others) can wear away at enamel and support cavity formation.

To neutralize acidity and prevent sensitivity, try drinking plenty of water, limiting your exposure to these items, and rinsing your mouth after eating or drinking anything acidic.

Sugar sensitivity is one benchmark I use when conducting a differential diagnosis on people with tooth pain.

Sugary foods and simple carbohydrates (white bread, white rice, baked goods, etc.) can encourage tooth decay and, in turn, tooth pain. Very short-lived pain when eating sugary foods is almost always caused by gum recession and decalcification.

Try sticking to a diet filled with nutrient-dense, non-acidic foods. I recommend a Paleo diet, which I follow about 80 percent of the time.

When you choose to have a “flex” meal or snack, keep it short—don’t drink a 20-ounce soda over the course of a few hours, for example. Then, remember to rinse your mouth with water right after and brush at least 30-45 minutes later.

Better diet is my #1 tooth pain remedy for non-localized pain.

6. Proper Dental Hygiene

It’s not uncommon to form bad dental hygiene habits—even I have to remind myself not to brush too hard on occasion!

To develop the best habits, start by using a soft-to-medium bristled toothbrush, replacing it once a month (or replacing heads for electric toothbrushes about once every three months).

Additionally, ditch the over-the-counter fluoride toothpaste, which is abrasive and can also wear down your enamel, and opt for a gentle option or no toothpaste at all.

You may be surprised to hear this, but it’s the motion of brushing—not the toothpaste—that is responsible for disorganizing the biofilm on your teeth.

If you have small cavities that can be remineralized, you may want to try a toothpaste that contains nano-hydroxyapatite (NHa) particles. I’ll explain this in more detail below.

Other ways to improve your dental hygiene routine include tongue scraping, coconut oil pulling, and flossing. Remember, mouthwashes that contain alcohol can actually worsen tooth pain, so avoid them.

7. Regular and Preventative Dentist Visits

Developing a relationship with your dentist can help him or her observe and treat any problems as they arise, and before they cause sensitivity.

Not only will your dentist take x-rays and physically examine your teeth, s/he should also be looking at additional factors that can lead to sensitive teeth.

For example, I conduct nutritional counseling with all my patients to pinpoint any possible reasons for tooth pain. I also measure exposed tooth size in my aging patients to watch for gum recession.

In addition, regular cleanings to remove plaque are important for preventing the demineralization that can lead to exposed dentin and sensitive teeth.

8. Sinus Infection Treatment

The best way to prevent or treat sinus infections is to eat an anti-inflammatory diet like the one mentioned above.

There is no cure for a basic sinus infection (sinusitis), but you may use decongestants, saline rinses, and pain medication to deal with the symptoms. Chronic sinus infections, on the other hand, might require an antibiotic prescribed by your primary care doctor.

Over-the-counter sinus decongestant sprays like Neo-Synephrine may also help alleviate some symptoms of sinus infection.

If you use the spray and notice that your tooth pain goes away, that’s a great indication that a sinus infection is at the root problem. That’s a revelation that can save you an unnecessary trip to the dentist.

Using mouth tape, such as Somnifix, to force nose breathing can be a great way to prevent sinus infections in the future. People with chronic sinus infections have decreased nitric oxide levels overall, which can be increased if you train yourself to nose breathe.

9. Resolution of Bruxism

If grinding is the cause of your sensitive teeth, you can discuss treatment with your healthcare providers.

More and more research suggests that underlying sleep apnea is often the trigger for night grinding.

So, instead of a mouth guard—which just protects teeth from the effects of grinding—aim to get to the bottom of your sleep apnea or other sleep disruptions.

10. Stress Reduction

Chronic stress can lead to increased inflammation in the body and, in turn, pain. This is often a secondary cause of tooth sensitivity compared to more direct causes that directly impact the teeth.

In addition to altering your diet to include more anti-inflammatory foods, reducing some of the extra stress in your life can help to prevent or reduce tooth sensitivity.

Some cases of bruxism are also related to stress. You may need to consider relaxation techniques to help your sensitive teeth caused by grinding.

11. Reducing Chronic Inflammation

Giving your body the best chance at low levels of chronic inflammation can help improve related pain in the teeth. This is especially true for people with diabetes.

Try eating foods that fight inflammation and avoiding the ones that cause it.

Sensitive Teeth FAQs

Do I need to see a dentist for my sensitive teeth?

At the onset of tooth pain or sensitivity, especially if that discomfort quickly rises in intensity, you need to see your dentist.

Worn enamel or a small, hidden crack in a tooth can be the wide open door for bacteria to enter, grow, and ultimately cause cavities.

You should definitely go to the dentist right away if your pain is in just one or a few teeth.

For sensitive teeth throughout your entire mouth, it’s okay to look at home remedies for tooth pain first. But call the dentist as soon as the pain becomes very severe, or if it doesn’t go away after treating it at home.

Should I use fluoride for sensitive teeth?

In the past, I’ve recommended prescription-strength fluoride for remineralization, including for teeth that have become sensitive. I’ve always advise against ingesting fluoride, but now a new scientific development has removed the need for fluoride altogether.

Toothpaste containing nano-hydroxyapatite particles strengthens and remineralizes teeth more effectively than fluoride and can help to desensitize teeth that have become particularly sensitive to hot or cold.

These particles are tiny, dissolved fragments of bone that integrate right into your teeth to help them rebuild. They’re also 100% non-toxic when swallowed, unlike fluoride.

What is the best toothpaste for sensitive teeth?

The best toothpaste for sensitive teeth is one that contains nano-hydroxyapatite particles. As I mentioned, these particles help remineralize teeth and also counteract demineralization that happens during the day.

My favorite nano-hydroxyapatite toothpaste is Boka’s Ela Mint Toothpaste, and I use it each night before going to bed.

You may also want to try a tooth desensitizing toothpaste like Sensodyne. However, many of these types of products contain products that may not be safe in large doses, so try to use it only as long as you need to in order to reverse the sensitivity.

Sensodyne’s regular formula is a great, short-term option for sensitivity.

How do you stop sensitive teeth pain?

The cause of your pain will determine how you stop the pain caused by sensitive teeth.

Localized pain needs to be corrected by your dentist. For pain throughout your mouth, you can probably start by treating it at home.

What causes sensitive teeth all of a sudden?

Sensitive teeth can sometimes come on very quickly. The most likely causes for this that I’ve seen are:

  • Rapid changes in diet (like eating a lot of acidic foods in a short period of time)
  • Teeth whitening
  • Growth of a tooth abscess or deep cavity (one day it doesn’t hurt, the next day it does)
  • Sinus infection
  • Trauma to a tooth that causes it to crack

How long does it take for sensitive teeth to go away?

If your sensitive teeth are caused by diet or other overall issues, you can expect them to get better within a week or two of altering your habits.

The length of time it takes to get rid of sensitive teeth varies by the cause. For treatments by your dentist, ask him or her how long you should expect to have any lingering pain.

Final Thoughts

The primary reason you experience sensitive teeth is that something has caused the enamel of a tooth or teeth to be worn away, exposing the sensitive dentin underneath. And since dentin is connected to your nerves, exposing this layer causes pain, which your dentist might call dentin hypersensitivity.

There are two basic types of sensitive teeth pain: localized and non-localized.

Pain in just one or a few teeth is a sign that you need to go to the dentist right away. This typically points to issues like cavities, abscess, cracked teeth, or problems with a recent dental procedure. For a severe toothache remedy, the dentist is your best choice.

Non-localized pain is more often caused by lifestyle changes, illness, or chronic inflammation. Most of the time, these issues can be treated at home.

To treat sensitive teeth, here are some of the major options you have for how to stop tooth pain:

  1. Have any damaged teeth repaired
  2. Get abscesses removed
  3. Treat your gum disease
  4. Have failed dental procedures corrected
  5. Change your diet (remove most acidic and sugary foods)
  6. Improve your dental hygiene habits
  7. Go to the dentist regularly
  8. Treat any sinus infections you develop
  9. Resolve bruxism
  10. Reduce stress
  11. Get rid of chronic inflammation

When you notice your teeth are sensitive, avoid over-the-counter mouthwash and start using an NHa toothpaste like Boka.

    what is sensitivity? and how the colgate sensitive helps the sensitive teeths

  2. I went to the dentist a month ago. I went in for a cleaning, amd he said that I had six cavities and he was going to go ahead and fill them. I thouvht he new best so I said yes. From that day on, I have lost six pounds because I can only eat food blended up and through a straw. I takle advil everyday, which is not good at all. All my teeth are extremely sensitive to hot or cold and the food has to be just right. Pain is so much that I have had swollen face and slurred speach. I have gone to see him three times to fix the pro lem, but he didnt even losten to me saying that all my teeth hurt all the time, crying when I brush my teeth, and now a swollen face. Nothing was wrong before I went in, no pain from cavities or anything else. I dont know what to.do, please advise.

    • Go to another dentist! Your dentist sounds terrible.

    • You need to see another dentist. This exact thing happened to me with two of my teeth. I went to another dentist and he removed the fillings and found that mercury fillings were placed directly on my nerve. Causing severe psin and swelling. I soon lost both teeth and had to pay thousands for bridges.

    • ken vanderhamm says:

      did he use mercury amalgam as a filler? Bad stuff!

    • After my dentist talking me into getting a couple cavities filled only to have one of the teeth fracture later, my motto is: if it doesn’t hurt, don’t fix it. Leave it alone. Try to improve your tooth health and hope that the cavities don’t get worse. Go to another dentist and get this problem sorted, and then don’t let them touch your teeth unless something hurts.

  3. my toothe not the second but third from the left top adult tooth is very sensitive i cant eat hard food

  4. I just had the same problem after taking antibiotics for 3 weeks for a sinus infection and tooth abcess at the same time. One nigh my whole mouth began to hurt so I went to the ER. I was told I probably had a fungal infection in the gums and mouth due to the antibiotics killing all the natural defenses in my mouth. I’m taking some medicine now for that and the pain has been relieved greatly, although not quite gone yet. I noticed the problem was more after I flossed than anything, but I still have to brush and floss –couldn’t go a day without doing that.

  8. I have had mild discomfort when chewing for some time. I had a flu shot last week, have been on antibiotics for an unrelated issue, had a fever (103.7) last night. We have fever down, and today I am with constant pain in my mouth. Sometimes it feels like it is the upper right and then it seems to be lower right. Very sensitive to cold beverages. See Dr. or Dentist?

  9. I have been experiencing the same problem as you guys. For several days now. Three days ago I went to see the dentist. He radioed my teeth and said I have no problem with my teeth. He did not even give me any drug. I thought the pain will go but it’s not happening. Getting worse. Went to the gym as usual and I noticed that after the gym it got even worse. I am really suffering while I am writing these lines. Advil relieves me a little bit but I cannot continue taking same over several days. Please help me

    • Look into the possibility of CRPS/RSD

  10. Both my wife and I experienced tooth pain in all of our teeth at the same time one day. We were staying at a Niagara Falls hotel with two of our kids. They had no issues. The only difference was that we both drank their coffeee from their buffet brekfast. Could it be a pot cleaner or the coffee or their water? It has stopped since then with no reoccurence.

  11. 3 days ago I developed pain in all my teeth, and now searching for causes, which brought me here. I can tell you what I use to alleviate the pain. MMS and DMSO. The first time I tried it was about a year ago in the Dominican Republic, where I learned a great deal about it. A very serious infection developed from a rotten tooth in my lower right jaw. I experienced a lot of pain and my cheek blew out like a chipmunk. I sprayed MMS on my toothbrush and added a few drops of DMSO on it, to help carry the activated MMS (Chlorine Dioxide)deeper into the root – DMSO has the innate ability to penetrate through membrane. Though I could have done more, I brushed my teeth with it a couple of times a day. The pain became tolerable soon after, and was completely gone in three days. Funny, this was a year ago, I still have that tooth, and no problems so far. Just waiting for a windfall to get it pulled out and get some work done,lol

    • What the hell is MMS and DMSO?

  12. Linda Yarbrough says:

    I had two crowns put on my teeth last week. This week the one tooth I had capped became very sensitive to hot or cold. Today the tooth is less sensitive than yesterday. I went to my dentist & she said after an xray that she couldn’t see anything wrong with the cap and suggested I go to a specialist for a root canal which costs $1000. I am questioning whether I need a root canal or not. Any comments on this would be appreciated.

  13. B Michaels says:

    While appreciate the systematic approach the dentist suggested to discovering the etiology of having ALL of ones teeth become hyper sensitive, some disorders, diseases, etc. go beyond retracing ones steps as advised. I’m not certain about others but in my case, this issue is way beyond a slight sensitivity or mild pain. Honestly, every single tooth has hyper sensitive to both cold and air. Worse, even room temperature water sends me jumping about and holding my mouth as if wounded. It is now to the point, that even in speaking the slight air used in the production ne pronunciation of certain sounds is causing me to speak softly and carefully. I have some serious medical problems and discovered tht I hold my breath and sigh a greet deal which is equally painful. Eating is a delicate matter as well. I’ve found little on this subject save a number of protesters of the Crest Prohealth toothpaste (which I admit I too was using and their may be merit to some of those claims?) However, given that I have autonomic dysfunction and various neuropathy I am concerned that this might tie into the Trigeminal nerve as it does in TMN, TMJ, etc? Could the dentist possibly comment on other symptoms that might factor into this nerve branch being involved? Perhaps someone else has encountered these symptoms? I appreciate the attention and wish better health to all..

  14. Lately, in the past six months, all of my teeth have become sensitive to the point I don’t want to eat. And toothpaste for sensitive teeth has just made my teeth more sensitive. That doesn’t make sense but it’s true. I don’t have a new favorite food I eat all the time that is high is acidity or any of the above reasons. I have always had a lot of stress, and this has never happened, and at my last dental appointment, I mentioned it, and the answer I got was, “we all experience tooth sensitivity at one time or another in our lives.” It’s been ongoing in the last six months. So, I don’t know.

      I’m experiencing the same thing. One tooth on the top left a couple back from the front in particular for the past few months. Had a regular cleaning and xrays and showed nothing wrong. The dentist said bone degeneration of the teeth and recession is happening but the past few days have been unbearable with pain on the left side of my face, now my front bottom teeth are sore today. I can’t drink cold or hot liquids. I’ve been using sensitive toothpaste and my health is excellent and my diet hasn’t become more acidic. It’s a frustrating mystery.

  15. All of my teeth have suddenly become very sensitive to cold, also when I floss I notice that my gums are sensitive to the touch. This is unacceptable because my only vice is ice cream. It does not feel like my sinuses are acting up. I have had some recent cortisone injections. Any idea what’s going on?

  16. Ive just had a partial pallet put in ( my old one was worn out ) and my teeth top and bottom on my right hand side have become sensitive why is this , when I went to my dentist for my 6 month check up they could not find anything wrong

    This post is SOOOO on point. I have a sinus infection and my upper back teeth are extremely sensitive and it is most evident when i walk! I thought something was terribly wrong with me! but then again i am a hypochondriac

  18. Two of my teeth suddenly just got sensitive and I know this might sound like the other person’s comment but it went away when I woke up and I’m kind of confused. One of my upper back teeth and upper front teeth started hurting when I touched them or moved them;I thought they were loose or something but I don’t think I feel anything now.

  19. My upper teeth feel like they are bruised and it causes me to have a pressure headache all the time. My dentist suggested that he file some of my teeth because he feels that my bite has shifted. My concern is that this filing will not work and then my good enamel will be gone and cause my teeth not to be protected. Any thoughts?

    • Pam, what your dentist is referring to is occlusal equilibration and it MAY solve the problem. Ask your dentist if you have a CR-CO discrepancy and if that’s what he would like to fix. It’s not a bad idea, although using Invisalign is the better method because it gets the teeth in the right place instead of trying to adjust them by removing enamel. Removing a little bit of enamel isn’t a bad thing, though.

  20. I have had this problem too. First the upper teeth on the left side suddenly became sensitive. Someone said it’s because I’m getting my wisdom tooth now. But it abated in a few days with some precautions. Later all the upper teeth on the right side became sensitive (starting exactly in the middle). I thought this would go away similarly in a few days. But it hasn’t. They are still sensitive, though not as much as before. Funnily, the lower teeth are all fine, except one in the middle. I used to drink hot beverages earlier, now I drink only luke-warm and eat ice-cream once in a while. I had braces at the age of 20 and had my teeth cleaned many times (could that be a reason for the sensitivity?). Does using Sensodyne regularly help or is it only a temporary relief measure?
    Thanks in advance for your answer, Doc!

    If you are facing this kind problem, it is best to seek immediate advice from a dentist before the problem worsens.

    Amazing information!! People will know very well how to identify the cause of sudden tooth sensitivity. I would like to thank to share this kind of effective information.

  23. Hello, I’ve been having problems with my teeth lately. When I went to fill in my cavities, I was only able to get one side for that day and had to wait 2 weeks for the other side to get filled in. However, my teeth have become sensitive (well they’re hurting) when I am just quiet and also when I eat/drink. I don’t understand why, and I asked my dentist. All he said was “it takes up to 6 weeks.” (like as if that helped) I don’t know what to do, and it’s almost a month I’ve dealt with the pain. Mostly at night before I brush my teeth, they start to hurt and I’m just quiet. I don’t understand.

    • Andrea, I’m sorry to hear this. Was it plastic or metal fillings? There are many reasons why teeth can hurt after you’ve had them filled with either metal or plastic. The most common reason is that the filling is too high when it’s placed – making the tooth cold sensitive about three or four days later – because the tooth is hitting too hard and doing too much of the biting force work and that makes the tissues inside the tooth ache. If you have cold sensitivity a few days after the filling, have your bite checked. It’s not necessarily the dentist’s fault, since when a patient is numb, they often don’t bite as they normally do, so it’s hard to know what the correct bite is at that time. A quick follow-up visit will solve that. Also, a strong acid etch is used when placing plastic fillings and the acid, if used too liberally, it can etch other tooth tissues nearby, and that will (for about a month or longer) make teeth sensitive to cold, sugar, and metal objects. Let me know if one of those describes what you’re experiencing.

  24. I started having sudden tooth pain about 2 days ago. But I’m not sure exactly what the cause is, since I have some oral piercings, one of which is occupied by a metal piece of jewelry and the other, plastic. I have had them for multiple years, but over the past 2 years, I have on more than one occasion, actually bitten down on the metal one, causing some teeth to get chipped. But about 6 months ago, I dealt with biting on it extremely hard and at first I thought I had cracked one of my teeth, but I haven’t been experiencing too much discomfort from it. Two days ago, I suddenly started having some pain in that particular tooth and within that first day, the rest of my teeth started hurting as well. There is no pain when I eat, drink, brush my teeth, or even suck in air through my mouth. The pain is there when there is no actual contact being made on any of my teeth. I cannot recall starting to regularly eat any specific food in particular. I’m not really sure what could be the cause of this all of a sudden. Any feedback would be helpful. I will be going to the dentist soon enough to hopefully get down to the bottom of this problem.

  26. I think that my teeth are hurting when I chew because I fell asleep with a jolly rancher in my mouth and it was on the side of my teeth. Could you help me?

    Remarkable! Its really amazing paragraph, I have got much clear idea
    regarding from this article.

  28. 4 days ago a tooth on top left hand side of mouth began hurting. Was very sensitive to cold and heat. I could not tell if it was the wisdom tooth or one up next to it. I went to my dentist. She always has wanted to pull my wisdom teeth for no reason so I’ve never let her! So, of course, she says it is the wisdom tooth. But the exists showed nothing. I made an appointment in two weeks and came home because I did not want her to pull it because I doubted her expertise. This morning I woke up and it is a different tooth hurting! It is directly under on the bottom row! The tooth that hurts now is on the bottom left hand side and is a tooth that has a crown. It is extremely sensitive to heat and cd and even when I touch it. When I chew food it hurts to bite on that side. I am confused about my teeth and pain? I’m glad I didn’t have the top wisdom tooth pulled because it is not giving me any problems. I dont have dental insurance so I want to make some good decisions. I regularly visit a dentist every 6 months but my long time dentist just retired. The new one I go to I don’t really think she puts much into what she decides to do.

  29. Above Should say *exrays showed no problem.

  31. My teeth at the lower part of my right jaw hurts since yesterday. I’ve never experienced any toothache in my 18 years of existence. Just this one, so I don’t have any idea of what is causes. But my mother says that maybe I have sensitive teeth. I just remember that for the past few days I drink lot of cold water after brushing my teeth and my mother said that drinking cold water after brushing my teeth is a wrongdoing. Is my mother correct? My teeth hurts that I can’t enjoy eating even my favorite food. If my mother was correct, is there some home remedies that may be help to treat this so called sensitive teeth of mine?

  32. i been having terrible problems with my teeth being sensitive to the point that i had two root canals already and they are not getting any better, also all my teeth were fine at first it all start when they change my old fillings for a new porcelain and my teeth start hurting me terribly, i had the old grey filling in one and the other ones were white but i didn’t had pain and now i can’t eat drink cold or hot, i am in so much pain that i have to take at least two Ibuprofen i need an answer if somebody can help please. a response will be very appreciated.

  33. Hiya.. I’ve had a small cavity filled 5 weeks ago and now my tooth is rather sensitive. I don’t think the filling is high because when I tap my teeth together and chew there’s no sensitivity yet the small area where the filling is, if I bite down on for example a pen I feel pain when I release the bite. I rang the dentist today and spoke to the receptionist who suggested I try a desensitizing toothpaste and if the sensitivity doesn’t subside in 10 days I should return and possibly require a root canal. I’m confused because the filling was very small no where even near the pulp and the dentist commended me for spotting the cavity. I’m rather OCD about dental care

  34. I started taking Levothyroxine for an under active thyroid about 3 months ago and since then my teeth have becone extremely sensitive to both hot and cold food and drink and they hurt pretty much all the time. I’ve started using sensitive toothpaste and it hasn’t really helped.
    Could the Levothyroxine be the cause? Nothing else has changed.

  37. Ive been having shooting tingling pains in the front right side of my teeth

  38. My mouth is in constant pain. Severe pain in my jaw muscles and joints. Feels like a cramp can never seem to relax my mouth or jaw. Now my upper front teeth are in pain too. A dull moderate constant painful sensation. Not painful to the touch or sensitivity to hot or cold or any types of foods. What to do…

  39. Steffanie says:

    Hi I was in severe pain all my teeth went bad i didn’t want too wait for the antibiotics and then pull them so I made them pull my two teeth upper left in the back came home got infected had a high fever was puking in severe pain. Went to hospital because my dentist wasn’t calling back they gave me antibiotics finally feeling better but now I have a sore throat and sensitive teeth. Is this caused by the antibiotics you think? I’m taking amoxicillin four times a day.

  40. Hi… Apparently I have a unique dental question. Is the nerve in my teeth alive? …I recently (2 weeks ago) fell playing tennis. I unfortunately hit my jaw and upper front teeth on the court surface. There was no sufficient pain with any teeth (none) but I noted three immediate concerns. (1) my bite could no longer close. The lower teeth were hitting the upper front teeth. (2) my lower jaw took most of the impact in the chin. (3) three upper front teeth left a impression on the court surface but they didn’t moved or shifted out position. And they didn’t hurt although one of the large front top tooth had some very slight movement, but it appeared to be in the correct position. I went to dentist and tested my 4 upper teeth between the canine teeth (2 pulled for braces) sensitive to cold. None of the four hurt like the canine teeth to cold. My jaw joint was soar but not fractured but likely inflamed and swelling. Dental x-rays didn’t reveal any upper tooth damage/cracks/ or out of position movement. The dentist gave me two injection numbing the upper teeth. And tried moving the upper teeth outward to release the lower teeth’s overbite. He said they didn’t move and seemed to be setting correctly in their sockets. He ground down the back side of my upper front teeth until my jaw would close. closed. The following day I noted my jaw and bite was closing as it normally should, the molars all fitting as I had remembered prior to the fall. On a return visit 2 weeks later there all upper teeth seem to have tighten up with no associated pain. But none of the 4 upper teeth are sensitive to cold. The two canine are. Is the nerve alive? Do I have to have root canal on each upper tooth?
    Sincerely hopefully not toothless,

  41. I’m going through a second period of sensitivity with all my teeth. The first time was well over ten years ago and cleared up on it’s own with a gel made by the same manufacturer of toothpaste for sensitive teeth (it’s more concentrated), but that time the reason was clear: I’d drunk a cup of very hot tea when just coming in from a freezing cold hike. The pain didn’t start till the next day, but it was extremely intense whenever I drank even a warm beverage. My dentist recommended trying the gel because he knew I had no issues with my teeth, fillings, crowns, or gums. This time, the pain is less intense but continues all the time, even at night. Ibuprofen helps a lot, but I don’t like taking it around the clock. That gel does help immediately. I’ve waited a week now, so I’m going to go ahead and contact my dentist. It’s not going away like the last time. One thing I’ll comment on: it seems that it might be brought on by a shift in seasons – this time our weather warmed up really early and then suddenly turned cold again. It’s the only trigger I can think of.

  42. I noticed some tooth sensitivity so I went to my dentist thinking I had a cavity. After X-rays showed nothing. He gave me amoxicillin for a week. I still had pain so he changed one of my metal fillings to white. I had a difficult time getting numb which never happened before. When at home later and the novicane wore off my whole jaw and other teeth on that one side hurt. I used ibprophen and Tylenol and a heating pad. After this I came down with Shingles but on my chest to back.
    My left teeth and jaw still hurt so went to the doc and he has given me flagil. It’s only been a couple of days yet but if that doesn’t work what do I do next? Back to my dentist?

  43. Hello,
    I really appreciate this blog post. When I’m thinking about teeth Care, then this website is the best place to find every information. Thanks for sharing this helpful article.

  44. I have one small part of my second molar from the back on the bottom side of my mouth (not including my wisdom tooth) that feels different to the touch of my touch, looks a slightly different color, and has a feel of pressure when I chew on that exact spot. It feels almost like a filling does recently after it is done (though I can’t recall if that tooth had a filling) and the pressure started after a weird crunching sensation a few days ago. What could it be?
