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’m excited to give this recipe a try!  I haven’t used fluoride toothpaste for years but am unhappy with most natural toothpastes.  I don’t care for coconut or almond flavors.  Do any of you have another suggestion to take the place of either of those oils?

    1. Stella Avatar

      Coconut oil tastes nothing like coconuts actually, if that is what you meant..

  2. Sue Avatar

    Seems like you could make it a bit thinner and put it in a squeeze bottle or dropper bottle.I like this. I use a liquid product myself, but it is rather expensive – especially if you are supplying a houseful of kids 🙂

    I had 3 cavities and was scheduled to get them filled.  I immediately started using Xylitol in my tea after reading about it being good for teeth.  When I went to get my fillings, the cavities were gone!  It happened again last week.  I had a small cavity and scheduled it to be filled, started using the Xylitol daily, went back to dentist, no cavity.  I need to make sure I used Xylitol daily or at least use this toothpaste recipe!

    I just mixed up a batch and tried liquid calcium. Is it okay, I noticed the baking soda caused it to bubble up and foam, then it settled back down again. How much stevia do you put? the parts thing meant I put 2-3 tsp, which it a little sweet even for me. wish me luck!

    My calcium carb also has a small amount of vit C,D,E ect.is that ok to use?

    I’ve used a tooth powder from the Edgar Cayce readings that’s called Ipsab Powder. It’s made by Heritage products and has salt, baking soda, prickly ash bark (used by Native Americans for teeth cleaning) and mint in it.  If you don’t want to go to the trouble of making up your own, this is a great substitute.

    Why don’t you just store the toothpaste into one of those squeezable 1-3 oz. shampoo/lotion containers that you can buy at the grocery store meant for traveling purposes? It seems just a tiny pea size squeeze onto your toothbrush and away you go to brighter, whiter, clean teeth!!! =)

    I just started making my own simple Toothpaste; baking soda, coconut oil (trop trad.) and peppermint oil. I love it – my mouth feels great and its Sweet even without the xylitol (i couldn’t justify spending $$ for a big container when i don’t use it for anything else, if it was avail in bulk and i could buy any amount i wanted then great, but it’s not) 🙂 I don’t like sweet anyhow 🙂

    Just jumping in here…made some just this morning and was kinda worried about the wretched taste of the castille soap and I am happy to say that there is no lingering soapy taste with this.  I added orange and peppermint essential oils and that, along with the xylitol, makes the taste rather innocuous.  I like the coconut oil in it as I used to brush some over my teeth after I would brush anyway.  Teeth certainly feel clean afterwards!

    I’ve been using this recipe for three days now (minus the DE). I’m definitely feeling some tingling in my gums, did I use too much of any of the ingredients? Also, since it tends to get dry, should I add more coconut oil or 1 part water?

    1. Wellness Mama Avatar
      Wellness Mama

      Did you use any essential oils? The tingling might be from that. if not, it could be your body adjusting to the higher pH in the baking soda. If it continues after a few more days, I’d try using baking
      soda alone and coconut oil alone and see if the reaction occurs with either of those. If the mixture is dry… just add more coconut oil.

    I was going to mix up a batch and got the peppermint Dr. Bronners, but right on the label it says it turns into glycerin when they are making it….so isn’t that bad? I thought glycerin was bad for mineral absorption into our teeth? On the main part of the label, under the certified fair trade line, “**None remains after saponifying oils into soap and glycerin” and then on the left side of the label in vertical type – “One of humanity’s oldest….All glycerin is retained….” Is this referring to the liquid soap or maybe just the bar soap? Please help, I really want to try this! Can I just leave out the soap? 

    1. Wellness Mama Avatar

      You can definitely leave out the soap without a problem, though the glycerin should just be retained in the bar soap, as far as I know. I’ll look into it more though.

    Are there any substitutes for the Castille soap? I can’t find any “pure” castille soap; they all have other ingredients added, like hemp.

    1. Wellness Mama Avatar

      A lot of the ones with hemp should be fine… any of the Dr.
      Bronner’s (except Sal Suds) are ok (mint is great for toothpaste)

        Thank you! I have seen Dr. Bronner’s with the mint at my local health food store. Looking forward to trying this!

    just wondering if you can use calcium citrate instead of calcium carbonate

    1. Wellness Mama Avatar
      Wellness Mama

      From what I understand, both would work, you just want to make sure
      whatever form of calcium has an “ate” ending.

    Just a warning to those who want to put this in an icing bag or zip lock, the consistency can change based upon temperature! While it may be pasty or almost dry when you mix it up, if it gets very warm or if you take it camping, the coconut oil will become a liquid at temperatures above 76 degrees.

    About using organic eggshells – how would you go about this?  Do you need to wash, bake, or dry the eggshells first?  What if you’ve hardboiled eggs – can you use those shells, or should you avoid heating them?  Thanks for your help! 

    I’ve been using baking soda/mint extract toothpaste for a couple months now, but I really like the idea of adding minerals and other healthy ingredients.

    1. Wellness Mama Avatar
      Wellness Mama

      I’ve used egg shells that have been washed well and just air dried. I
      don’t see any reason why heating would necessarily be bad, but I also
      don’t think it would be necessary.

    Regarding the comments on oils and septic systems, dish washing detergents will break up the oils.  Regular soaps do not, necessarily.  I have always been more concerned about the salt and baking soda going down the drain, since they are anti-microbial and the septic relies on bacterial activity to break down waste.  Get Rid-X and use it per the instructions and keep the system pumped when you are supposed to and it should be fine.

    Regarding DE, I would think it would be abrasive, unlike salt or baking soda which will dissolve when wet.  But being somewhat abrasive would not necessarily be bad if one desires to remove food stains from the teeth.  One thing to keep in mind about salt – if it isn’t ‘refined’ such as many popular sea salts, it may contain many trace minerals which will not dissolve and therefore add to the abrasive-ness. 

    In any event, the true benefit of brushing will come from the mechanics of brushing.  While different formulations of tooth powders and pastes may enhance the process to one degree or another, the idea is to cleanse the teeth of food debris, sugars and to disrupt the formation of plaque or bio-film – and so hopefully preventing the colonization of pathogens responsible, in large part, to tooth decay and gum disease.  To me, brushing several times per day (2+ minutes) with nothing more than a toothbrush would be more advantageous than brushing twice a day with the best dentifrice formulation.  Put the two together, though, and I think one would not have to worry a whole lot about losing one’s teeth due to decay.

    Hello, I am soaking up many of the wonderful recipes you have been listing on your website. Thank you for all your help in responding my questions! I have been hesitant to make toothpaste because I keep reading information about baking soda being too abrasive. My dentist had also told me to stop using it on my teeth when I used to brush with it. What is your take on the need of abrasives in toothpaste? Some people say all we need is a toothbrush and water. Thank You!

      I’ve heard of the toothbrush and water technique too, though never
      tried it. I do know that if you are eating a healthy diet, you are
      less likely to get cavities, all other things being equal. as for
      baking soda being abrasive… I had a regular dentist tell me that
      also, and asked a natural dentist about it. The natural dentist told
      me that it is actually not abrasive at all, especially compared to
      most other toothpastes. This site seems to back that up, with plain
      baking soda being really low on the list of abrasiveness, and many
      normal toothpastes being quite abrasive.
      If you make this, especially with the calcium powder included, it
      should not be abrasive at all and should help provide the minerals
      need your teeth need to strengthen.

        You could also just swish with baking soda or sea salt to get rid of bacteria, and then brush before or after.

    Do you have any concerns about spitting the oil down the drain?  I live in the country with a septic system and DH is always insisitng wiping fatty oils off of dishes with paper towels/napkins as best we can before washing them since the fat can be bad for the septic bugs.  Obviously, there’s not a lot of fat in each use of the toothpaste, but if the whole family uses it multiple times through the day, it can add up.  I could of course spit in the trash can or something, but I just wondered if anyone else had any thoughts on this.

      Good question. We are on a septic system too and haven’t had trouble
      with it, but if there is a concern, spitting in the trash can might
      not be a bad idea…

      1. Helen Avatar

        I have read that you should never spit the oil from oil pulling down the drain or in the toilet for it is not good for the plumbing. Always spit in the trash . Also use a separate toothbrush just for oil pulling. You do not want to contaminate your regular toothpaste. I love oil pulling and am so happy to find this recipe for brushing teeth. I am anxious to try it. I get fresh pastured eggs from a friend ( free mind you)—blessed. I am going to utilize the egg shells. I love all of these suggestions.

      Wouldn’t the soap in the mixture break up the fats enough that they shouldn’t be an issue?

    3. Natalie Avatar

      I always spit the oil from oil pulling in the garbage for this reason.  That would really clog it up over time.  The use in toothpaste like this would be much less, but still might be a good idea to spit in the garbage.  (I just make sure I have a liner in there all the time now, and try to change it often.)

    4. Mog Avatar

      You should NEVER, NEVER, spit coconut oil down the drain. Coconut oil is an oil that hardens when cool and over time even small amounts will clog up your plumbing and septic system very badly. The best thing is to spit the oil into a ziplock back and dispose of along with your garbage. If you have a compost, I understand small amounts of oil in your compost is fine. Apparently it’s the large of amounts of oil, such as you might use in frying, that is a problem for composts.

    Thank you for this recipe!  I tried it and love it.  I added one part pure water to keep it smoother and from drying out.
