Remineralizing Mouth Rinse: Easy DIY Recipe

Updated on
remineralizing mouth rinse

Modern dental care has taught people that the only way to treat cavities is to fill them. But there are other options. In fact, my remineralizing mouth rinse can support your teeth’s natural process of rebuilding—and even reverse smaller cavities if you catch them early enough.

Sound too good to be true?

Well, it’s not.

Cavities are caused by a combination of multiple factors in the mouth, including an acidic pH, a lack of mineral-rich saliva, and the presence of bacteria that feed on the remnants of certain foods before excreting cavity-causing acids onto the teeth.

But when these factors are controlled and optimized—that is, when pH is neutralized, the mouth is producing adequate amounts of healthy saliva, and the oral microbiome has the proper balance of good and bad bacteria—it’s not just possible to prevent future cavities.

You can also reverse cavities that already exist.

And that’s where this remineralizing mouth rinse comes in.

Now, there are times when fillings are the best choice for treating decay. But I want everyone to know that there is, in fact, an even better option.

The only problem? Common lifestyle choices disrupt the remineralization process and make it difficult for teeth to heal and rebuild from decay.

If you want to create the ideal oral environment for healing cavities naturally, eating the proper diet and taking oral probiotics and other supplements that support remineralization is important.

It’s also important to avoid dental hygiene products that can interfere with the process of remineralization—and conventional mouthwash is one of the biggest culprits.

If you’re one of the millions of people who uses mouthwash daily to improve bad breath, whiten teeth, or clean hard to reach places between the teeth, you should know that mouthwash can’t actually do any of those things.

In fact, conventional mouthwash does more harm than good and can actually cause bad breath and cavities.

Antibacterial mouthwashes destroy the mouth’s beneficial bacteria, leaving it dry and encouraging the growth of the bad bacteria you were trying to rid of in the first place! (1) A dry mouth is more prone to cavities because the production of saliva is needed for the remineralization of your teeth, and a reduction in saliva also contributes to bad breath. (2)

There are some natural mouthwashes that are a better option than Listerine and similar products, but it’s also really easy—and even healthier—to make your own mouth rinse at home.

This DIY Remineralizing Mouth Rinse supports the oral microbiome, rebalances the mouth’s pH, thus supporting the natural remineralization process.

Let’s take a closer look at the ingredients:

L-Arginine is an amino acid supplement that helps prevent tooth decay while preserving the health of the oral microbiome. (3)

Calcium carbonate is a gentle and safe way remove debris and surface stains.

Anise will help freshen up your breath. (4)

Algae is a natural pH stabilizer that moisturizes the mouth.

Now, for the recipe:

  1. How long should this last before spoiling and do I need to refrigerate? Thanks! Also.. how would I keep the water hot to soak the anise?

    • Mark Burhenne, DDS says:

      Hi there, Caroline!

      As long as the water is hot when you begin soaking, there is no need to keep it warm. Kind of like making a tea 😉

      For storage, thank you for bringing this to my attention. I’ll get it added asap!

      • Great DIY! Also wondering how long and how I can store the mouthwash 🙂

        • Mark Burhenne, DDS says:

          Up to 2 weeks is fine!

          • Does it require refrigeration? Thank you!

    • Katherine says:

      Is this mouth rinse safe for children?

  2. Questions:
    1/ The first instruction says to remove the star anise from the water. I’ve never seen it sold in water. Should the first instruction be to soak it in water? If so, how much water?
    2/ I know where to find star anise locally, but where does one buy the other ingredients?

    • Mark Burhenne, DDS says:

      Hi Cathi!

      The ingredient’s section says, “2-3 pieces Anise (soaked in 1 cup hot water for as little as one hour or up to 24 hours)”. So sorry if this wasn’t clear!

  3. Does this have to be refrigerated?
    How long does this keep before spoiling?
    Can I substitute the anise?
    Can I add xylitol?

    Hi! Thanks for this awesome DIY mouthwash. I was wondering should I use another mouthwash alongside this or is this good enough on its own? I was thinking to buy the Lumineux mouth wash you mention but am unsure whether I should use it as well as.
    Also, I live in the UK and it is hard to buy the mouth wash that you mention on the site. It’s also very hard to find websites which give this information which aren’t in some way swayed by toothpaste companies etc. Could you possibly review toothpastes/mouthwash for the UK market? That would be amazing!

    Many thanks!

      Hi there, Nathan!

      There is really no need to purchase an over the counter mouthwash as long as you’re using one of my DIY’s.

      Best wishes,

      Dr. B

    Where can I purchase blue green algae? i greatly appreciate the links to buying the other ingredients- however this one has me stumped.

  6. Love this recipe and have been using it for a couple of weeks. Thank you!

    I’m wondering how I am supposed to know what is considered a minor cavity? I’ve made it to 38 without any cavities but recently noticed some decay around a couple of my molars at the gum. The teeth don’t seem to pain yet. I’d love the thoughts of getting away without the need for fillings but how long do you suppose it takes to rebuild when using this rinse? And provided all the other factors at followed – probiotics, green diet, etc

    How do I get 1/2 tsp from tablets? E.g. L-Arginine is in 500 mg tablets.

  8. RE: Invisalign Teeth care. I have been wearing Invisalign for the past year and I am developing cavities. I am trying to remineralize my teeth with the things I have read on here, my diet has always been clean. If anything I probably brush my teeth with to much toothpaste and brush to long. I think my problem is the tooth paste I use was drying my teeth out. While I am switching that, can you tell me if I do coconut oil pulling before putting my Invisalign trays in for the night, will that help stop the decaying process? Help to restore my Microbiome?
