How to make your own remineralizing toothpaste with natural ingredients

I’ve talked before about the link between nutrition and oral health and the ability of teeth to remineralize and regenerate and shared my own experience with reversing a cavity. The approach I used was two-part: addressing mineral levels in the body/saliva and using a natural remineralizing toothpaste that provided minerals to the surface of the teeth.

A Remineralizing Toothpaste

There is a lot of emerging information about tooth remineralization, a process that many dentists previously thought was impossible. This article goes into detail about the science behind tooth remineralization and the dietary steps necessary. (It also explains why ingredients in most toothpastes, even natural ones, are not optimal!) I also did a podcast interview with a dentist who explains the science of remineralization (listen here).

The information I found in researching this was mirrored by my own experience over the last few years with natural toothpastes and a remineralizing diet.

Natural Toothpaste

I’ve noticed definite changes in my teeth over the last few years of using this toothpaste. My teeth are whiter than they’ve ever been and everyone who I’ve asked to try this remineralizing toothpaste has remarked that it makes their teeth feel very clean.

The most surprising change in my teeth, however, was that they are no longer sensitive to cold! For as long as I can remember, biting into anything cold (or even thinking of it!) made me shudder and hurt my front teeth. After switching toothpaste, I noticed that I could eat cold foods without my teeth hurting at all. I have never been able to do that before!

This toothpaste recipe is kid-approved, and since it has no fluoride, it is safe on babies, toddlers, and those with thyroid problems.

Remineralizing Toothpaste Recipe

Make a remineralizing toothpaste with calcium powder, coconut oil, xylitol, baking soda, and essential oils.
Prep Time10 minutes
Author: Katie Wells



  • In a bowl, mix together the calcium powder, diatomaceous earth, baking soda, and xylitol.
  • Add the coconut oil one part at a time until the desired consistency is reached.
  • Add any optional essential oils for flavor.
  • Store in small container such as a ½ pint glass jar.
  • To use, either dip a clean toothbrush into it, or use a popsicle stick or small spoon to scoop it onto the toothbrush.


For this recipe, “part” denotes whatever unit of measurement you are using. For instance, if part=tablespoon, you would need 5 tablespoons calcium powder, 1 tablespoon diatomaceous earth, etc.
Or, skip the recipe and try my Whitening & Remineralizing Toothpaste from Wellnesse!

The Internal Side of Remineralization

It is really important to note that remineralization is not a process that happens only in the mouth and that simply using a toothpaste (like the one above) with a higher concentration of minerals will not likely be enough to help teeth. Remineralization is a whole-body process and in order for it to happen, the body must have adequate levels of certain nutrients, especially fat-soluble vitamins and certain minerals.

When I was actively working on remineralizing my teeth, I focused on consuming a very specific nutrient-rich diet, reducing mineral binders like phytic acid in the foods I ate, and adding other lifestyle factors that boosted nutrient levels.

You can read my daily oral health routine in this post.

These additional factors like consuming enough minerals and fat-soluble vitamins are important not only because they support the body as a whole, but also because they create more mineral-rich saliva, which is the body’s delivery system for necessary nutrients to the teeth.

How Saliva Benefits Oral Health

In short: Saliva is the way teeth remineralize!

On a practical level, teeth are remineralized through the saliva being washed over the teeth. Without proper nutrient levels in the body, saliva will also be deficient in the minerals teeth need for optimal strength. Clearly, we must have sufficient nutrition in our diet in order to have the necessary minerals present in the saliva to support remineralization.

The importance of enough saliva for the prevention of tooth decay is well established. There are multiple theories about the origin of tooth decay:

  1. That decay occurs due to acids from bacteria in the mouth digesting sugars; or
  2. That tooth decay occurs when there is an imbalance between the demineralization of the enamel surface and remineralization produced by the return of mineral ions into enamel (as explained by Rami Nagel in his book, Cure Tooth Decay)

Whichever theory is correct, saliva is important, as the frequent stimulation of saliva, especially after the intake of sugars, will help to dilute and buffer plaque acid, bring extra mineral ions into the plaque fluid and thereby promote remineralization.

Saliva Reduces Bacteria that Cause Gum Disease and Tooth Decay

Research shows a clear relationship between declining saliva production with age and the increased risk of gum disease with age. Saliva contains a whole host of vital substances for our immune system.

For example, lactoferrin is one compound naturally found in saliva. Lactoferrin is part of our innate immune system and is one of our key front lines of defense. Lactoferrin binds iron in the mouth depriving the gum-damaging bacteria the iron necessary for them to flourish.

Saliva is also a rich source of necessary enzymes. Of the salivary enzymes involved in maintaining the ecology of the mouth, one of the first to be recognized was the enzyme lysozyme, which appears to work by destabilizing the cell wall of bacteria that cause tooth decay and gum disease.

Saliva Reestablishes Healthy pH in the Mouth

The mouth has its own complex ecology that must be kept in balance for optimal oral health. This includes a bacterial aspect, the presence of enough minerals, and maintaining the proper pH. While we can most effectively address optimizing the pH of the mouth through immune supporting protocols like a nutrient dense diet, restful sleep, and healthy coping tools for stress, saliva clearly plays a key role in the actual mechanism of establishing what the pH of our mouth is going to be at any given time.

How to Increase Saliva Production

The principle “Use it or Lose it” applies when discussing saliva production. We must exercise our ability to produce saliva or deal with a dry mouth and all the ails that come with decreased saliva production.

While we naturally produce additional saliva when eating, the extra benefits to our health of the increased saliva are offset by the main job of saliva during eating, to begin the digestion process. Therefore, it can be helpful to increase saliva production through other methods, like this:

Step 1: Gather any saliva in your mouth into a pool on your tongue. Now using the musculature of the throat, draw the saliva back and forth from the back of the tongue to just behind the front teeth then back again several times (we recommend 30-50 repetitions). With practice, this action will increase the amount of saliva present in the mouth.

Step 2: Once you have a large pool of saliva on your tongue, give your teeth and gums a bath with your increased saliva! We call swishing with saliva “swashing” because it’s like you are swishing and washing at the same time. Swash with the increased saliva for a minute or two then swallow it down and let the saliva now support greater digestion in the stomach!

This is such a simple technique even young children can do it. This video explains more:

Using a natural toothpaste can also help increase saliva production. I’ve noticed a saliva increase with this remineralizing toothpaste, and also with the OraWellness Brushing Blend.

    I bought Calcium Citrate powder instead of Calcium carbonate. Is that okay to use or do I have to go and by the Carbonate instead? 

      1. Helen Jackson Avatar
        Helen Jackson

        Someone in the comments said not to use the calcium citrate.
        This can get confusing with all of the different opinion.

    What brand of castille soap do you use. I found Dr . Bronner’s but can’t find it just plain?

      1. Nicole Avatar

        How much do you suggest to putting in your recipe above? It’s not included. Thanks….excited to try this and give feedback in the future 🙂

  3. Sam Avatar

    This might be really dumb, but I thought that essential oils shouldn’t be ingested.  Are they okay since you are spitting it out?  Thanks!

      There are some that actually can be but since these are used in the mouth and spit out, they are fine. YOu could also use mint extract if you were worried about it.

    I just made this toothpaste with very few variations.  It doesn’t taste too good – I think I added way too many awful tasting ingredients ;p but my teeth look and feel super clean!!! – thank you 😀

    5 tbs calcium powder
    1 tbs French clay (might reduce to 1 teaspoon next time or less, it might be contributing to the yucky taste ;p)
    3 tbs xylitol
    2 tbs baking soda
    1 tbs Castile soap (hmmm, it does taste like soap… maybe use less)
    5 tbs coconut oil (very soft, not entirely melted)
    1 tbs vegetable glycerin
    1 capsule GSE 125mg (this might not make it taste too good…)
    10 drops tea tree oil (gosh… just tasted this alone YUCK!)
    13 drops liquid stevia
    might want to add mint oil next time… taste is not too good but teeth are super clean 😀

      Next time, I’d suggest not adding the glycerine as it can discolor the teeth..

      1. Tere C. Avatar
        Tere C.

        yes, I just read some more comments after I added the glycerin and learned that it is not good for your teeth ????. thank you, you are nice and take the time to respond and help so many people, such an inspiration!
        thanks again and many blessings ????

    would adding cod liver oil or ghee make any good effect?

      The cod liver oil might, but I’m not sure I could handle the taste!

    I love your toothpaste! My 3 yr old says Yuck! every time, but she’s already getting used to it! My 2 yr old doesnt mind at all 🙂 Thank you so much!

    The benefits of xylitol are amazing for your teeth!  I am a RDA and have been preaching about it  for about 4-5 years now.  It basically tricks bacteria that causes cavities into not sticking to the teeth. When buying gum you should look for it to be the first ingredient.

    What about using liquid Trace Minerals?  Would you still use baking soda or not?  Thanks for all your awesome recipes!!!!  I use alot of them! 🙂

      I’d still use the baking soda for the cleaning and alkalizing, but some liquid trace minerals would be great to add!

    I stopped using toothpaste one year ago, because I dont want all the bad things in it like flouride and glycerin. I tried using a toothsoap but after a couple of months my teeth got discolourated, and I have never had that problem before using the normal toothpastes. Now I use an all natural toothpaste which consists of fermented grains and a little salt. But I still have the discolourations. I dont want to use the normal toothpastes again. Do you think this will help on the discolourations? Do you think I can use himalayan salt instead of calcium carbonate?

    I dont understand why I get the discolourations. I brush for a very long time, and I dont drink cofee or tea and I dont smoke, and I eat healthy food. People always say that you must not use any abrasives, but my teeth certainly dont get clean if I dont use any.

    hey does anyone know if Walmart has any castile liquid soap. the reason why im asking this is because when i tried looking for it on there website they just gave me different brand name soaps, so im hoping someone can help clear up this confusion. I’d really appreciate.

    1. Ashton Avatar

      Walgreens definitely does, but I’m not sure about  Walgreens.  The only brand of liquid castile soap that I see at stores like that is Dr Bronner’s, which is a tall clear bottle with a colored label that has a lot of text on it.  

  11. jessica Avatar

    hello! perhaps it ought to be obvious but i’m just wondering what is the purpose of  the addition of the calcium powder? and thanks so much for sharing your recipe it’s very generous of you, can’t wait to give it a try!

    1. Wellness Mama Avatar

      It alkalizes the mouth and is one of the minerals needed for remineralizing.

      1. Peggy Avatar

        I’m finding different types of calcium. Why did you prefer the calcium cabonite to the calcium citrate. And I think I saw a calcium phosphate.
        Which would be the best one.
        And being a few years later, how is this working out for everyone?

    Just FYI, Xylitol is extremely poisonous to dogs, so just be careful.  If ingested by dogs it causes an extremely rapid release of insulin that drops dogs’ blood sugar levels fatally low.  Sugarless gum often has it & as little as one stick of gum can kill a dog.  Toothpaste is less likely to be left where a dog can get into it, but the liquid is sweet, so just be careful.  

  13. Berri Avatar

    I wouldn’t use the Xylitol as there are concerns it may cause tumours.

    1. Jo Murphy Avatar

      Discussion of that here and in the comments. Not sure it’s an active concern.

    I don’t know why I couldn’t find any information like this years ago, I had several teeth that went from bad to worse and disabled with no health insurance for several years. I used to search incessantly for some natural way to treat those cavities, then about 6 months after I finally had to have most of my bottom teeth pulled I finally start to see information like this! Now can you tell me how to grow them back?? lol Just one question… why soap? 

  15. Faith Avatar

    Peace! Some good ideas here for sure, but it’s important to note that glycerin actually prevents the teeth from re-mineralizing & therefore should not be used. Dr. Bronners liquid castile soap contains glycerin so just a warning for those who are using this as part of their toothpaste.  I personally have had great results with just baking soda & coconut oil (50:50) with the occasional addition of peppermint oil.

  16. Danielle Avatar

    This doesn’t exactly seem septic safe because of the coconut oil…but maybe I’m wrong? hahah I’ve actually been brushing my teeth outside since I realized this because I fear the affects of the oil in my septic system…. any suggestions on an alternative for the coconut oil??

    1. Wellness Mama Avatar

      Can’t really sub it out, since it is part of the naturally anti-bacterial and anti-fungal part. I usually spit mine in the trash can or outside just in case. I’ve also read that liquid castille soap will break down the oil some, so you could add this to help also.

      1. Callie Avatar

        Katie, what about using MCT oil like you use in your simple natural whitening recipe? Can I use MCT instead of the Coconut oil so it wont harden?

    Can you please tell me a little bit more about castille soap – which ones are safe to use and the purpose?  I have not been able to find it in any stores around me and was going to order through iherb but the ones I looked at said “external use only.”

  18. Dawn Avatar

    I just tried the simplified version (the one minus all fo the optional ingredients) with Dr. Bronners castille soap and my tongue tingled!  So wierd!  But it felt like it was working already!

  19. Aries Avatar

    Hi. I would really like for you to record this on video and post it on youtube.  Looks interesting. What was the total cost for the ingredients?

    Can someone list the recipe and yield for me please.
    Math is not my strong point, and I am almost out of toothpaste!
    Also, has anyone been able to make a creamier version of this recipe?
    I hate scraping it out of the jar!
