Homemade Remineralizing Toothpaste


Remineralizing toothpaste - Dr. Axe

Why Should You Use a Remineralizing Toothpaste?

My Homemade Baking Soda Toothpaste has mild remineralizing qualities, due to the xylitol and clove oil. So does my Homemade Probiotic Toothpaste, due to the bentonite clay, xylitol and clove oil. But, for powerful remineralization action, you’ll need to up the ante a bit.

This homemade remineralizing toothpaste takes advantage of the remineralizing powers of bentonite clay (rich in calcium), xylitol (its sweetness also helps cover the taste of the bitter ingredients), calcium phosphate, magnesium chloride and clove oil (1).

It also contains cacao powder. Cacao (raw chocolate — not to be confused with cocoa, which is a highly-processed product) is the best-kept secret in tooth health! It has been shown to fight tooth decay by suppressing the bacteria that cause it and making it harder for them to coat teeth and gums (known as plaque) (2, 3). In toothpaste, cacao powder also acts a mild abrasive. And perhaps even better, it tastes really good, making tooth brushing a pleasure (and helping to cover less pleasant flavors). Hint: if you can’t brush, chew a few cacao nibs for a tasty, on-the-go, tooth cleaning.

We may think of our teeth as permanent structures. But the mineral building blocks (mostly calcium phosphate) in our teeth are in a constant state of flux, with some building blocks leaving and other new building blocks coming in to replace them. If more building blocks are leaving than returning, you end up with porous tooth enamel (the outer layer that is supposed to be super-hard), which is more susceptible to tooth decay bacteria. This net loss of minerals is called tooth demineralization (4).

What can you do to prevent tooth demineralization?

A high-stress lifestyle and eating a Western diet are both associated with tooth demineralization and tooth decay. So managing your stress and following a low sugar, low phytic-acid diet that is rich in minerals and fat-soluble vitamins are two good places to start.

Dry mouth has also been associated with tooth demineralization (5), so making sure you have a healthy amount of saliva is also important. Drinking plenty of water supports good saliva production. If your mouth remains dry, try practicing oil pulling, rinsing your mouth with a solution of slippery elm powder, or sucking slippery elm drops. You can make your own slippery elm drops, but don’t get carried away and suck them all day long as even healthy honey can promote tooth decay. In fact, it’s preferable to use a Manuka honey toothpaste instead.

But can you turn tooth demineralization around?

Yes! Encouraging more mineral building blocks to repair porous enamel and mildly decayed spots on your teeth is called remineralization. And it is a proven technology. This is great news because intact original teeth are better looking, stronger, and longer-lasting than teeth with even the best fillings in them (plus you are saved the discomfort of drilling and filling cavities).

If your teeth are prone to decay, you may well benefit from a remineralizing toothpaste, which is a common way to deliver remineralizing compounds.

What’s in Remineralizing Toothpaste?

Until very recently, toothpastes designed to remineralize (repair) enamel were prescription-only and all contained high levels of sodium fluoride (NaF), a substance that has been shown to be dangerous to your health (and many still contain this chemical). Thankfully, dental researchers are starting to look for more ways to turn minor tooth decay around. Even better: you can now buy safe remineralizing toothpaste without a prescription or make it at home.

Here are two safe, natural remineralizing toothpaste ingredients that even mainstream dental researchers agree can help remineralize teeth (not that your dentist may have embraced them yet):

Calcium phosphate. Toothpaste containing calcium phosphate (a bioavailable form of calcium found in dairy products, also called amorphous calcium phosphate and casein phosphopeptide-amorphous calcium phosphate/CPP-ACP), has been shown to be an effective way to remineralize teeth, with results appearing in as little as two weeks (6, 7, 8, 9). Such toothpaste has also been found to be more effective than fluoride treatments and fluoride toothpaste for remineralizing porous enamel (10).

Magnesium. Magnesium deficiency is prevalent in the Western world and has been linked to a wide range of conditions and diseases, including tooth decay. (11) Teeth with higher magnesium content have been shown to be less prone to decay. (12) Tooth gel containing calcium glycerophosphate, magnesium chloride and xylitol has been shown to reverse early tooth decay spots. Two 15-minute applications significantly reduced tooth sensitivity in most subjects (13).


Although remineralizing toothpaste can be quite effective at preventing, stopping and even reversing mild tooth decay and gum issues, it isn’t a substitute for seeing your dentist for regular exams and professional care of advanced tooth decay or gum disease.

Homemade Remineralizing Toothpaste

Total Time: 20 minutes


  • 2–3 tablespoons of organic cacao powder OR bentonite clay OR a combination
  • 3 tablespoons organic coconut oil
  • 1 tablespoon granulated xylitol
  • 10 drops magnesium oil OR trace minerals OR 5 drops of each
  • ½ teaspoon calcium powder (calcium phosphate if possible); use a full teaspoon if you don’t use any bentonite clay
  • 3 drops clove essential oil
  • 3 drops vanilla oil


  1. Measure dry ingredients into a small glass or stainless steel bowl.
  2. Add the coconut oil (if it is solid, liquefy it first by setting the container in a bowl of hot water for 10–15 minutes, coconut oil melts at 76 F) and stir until completely combined.
  3. Add the liquid ingredients and stir until completely combined. The xylitol crystals may still be visible; that’s fine.
  4. Store in a small glass jar with a lid.

      Xylitol is a natural 0 calorie sweetener. However, I prefer Stevia or Monk Fruit instead because too much Xylitol can cause diarrhea.

      • Jaclyn on

        Monk fruit works well in lieu of this recipe? I don’t like to have xylitol in my home because of it’s risk with animals (and one of my dogs is Houdini), so I was hoping something else might be okay.

      • Laura on

        Xylitol does help with tooth decay though. I don’t use it as a sweetener for treats but I’ll let my older kids use it in a toothpaste and spit it out. Just bought some organic for $8.

      • Debbie on

        I’ve read that xylitol actually helps prevent decay, so it’s doing double duty. The small amount in toothpaste, especially since you don’t swallow it, shouldn’t cause diarrhea.

    • Brenda Ludlow on

      Hi Shannon, Xylitol fights the cavity causing germ, so does Coconut Oil. I read a scientific study where the cavity germ couldn’t survive after 30 minutes of exposure to coconut oil. A different study tested sinus germs against Manuka honey and nothing that caused sinus infections could survive being exposed to Manuka honey. My Xylitol is KAL brand. It is poisonous to dogs, so if you have a furry friend, keep the xylitol out of reach.

      • lucia on

        I’m also no fan of Xylitol, it might have adverse effects on your liver too. I’d go for stevia but not the manipulated kind, the green tincture from the plant that’s what you need, it also fights germs and the germfighting you can also achieve with essential oils. My choice would be lemonoil, manuka and clove beats any bacteria, anywhere, anytime. Other than that the recipe is very good and balanced….. love you dr Axe, always a big fan.

  1. Debra on

    Can the magnesium oil sold by dr. Axe be used as an ingredient?
    Where can vanilla essential oil be purchased?
    Where to purchase trace oil?

  2. Margaret Smith on

    Isn’t xylitol deadly to pets, especially dogs? If so, should this home made remineralizing toothpaste be kept safely out of reach from curious cats and dogs?

    • Debbie on

      I’m guessing regular toothpaste with fluoride wouldn’t be good for them either, but just keep anything you don’t want them to eat in a container with a lid, in a cabinet if they might chew through the container. I’ve got a dog that sure loves to chew.

  3. Sandra on

    Coconut oil solidifies below 76 degrees. You can put the jar in hot water long enough to cause it to soften or just scrape it off onto the brush in the solidified form. Solidifying and liquifying doesn’t change its effectiveness.

  4. Jenna on

    hey everyone! i invented a super wonderful and effective remineralizing paste for anyone who is interested. it contains ozonated coconut oil, homeopathic cell salts, herbs for tooth decay, tooth-healing vitamins, bee propolis, coral calcium, bentonite clay, and trace minerals!! it’s amazing :) and has amazing remineralization properties

    for anyone interested, you can find it at

  5. tim on

    What about Calcium Bentonite? I have the “aztek secret” powder. Would that work as the bentonite and calcium, or should I still add a calcium powder?

  6. Grace on

    Its a little unclear to me as to why you use the vanilla oil for the paste. What is the reason why? Also, how long does this last, how do you store it? Will it is grow anything in it after a certain amount of time?

  7. DW on

    I am having a hard time finding calcium phosphate. I only found Source Naturals Calcium Ethanolamine Phosphate with no information on it. Plus it’s in tablet form. Where can I buy some?

  8. Nadine on

    I’m having real difficulty finding calcium phosphate in Canada. Is there another form of calcium I can use that is equally as good. Thank you. I am really looking forward to making this toothpaste.

    • Brenda on

      Hi Nadine, I bought it online through Amazon. I spent upwards of $100 on all this stuff. I can make toothpaste for the rest of my life.
      😀. Maybe check the other comments and buy the toothpaste from the woman who is selling it. I like the way it turned out.

  9. Elizabeth on

    This sounds great to try, however, I would caution anyone using coconut oil in this to spit it out into the trash and not down your drain. As the coconut oil hardened in the jar, so I assume it will harden in your pipes causing blockage.
    On another note, can one use dried, powdered egg shells for the calcium?

    • Shawn on

      Clove is excellent for oral health. You could sub melaluca and mrryh essential for medicinal properties and peppermint for taste. Or a protective blend.
      Only use Certified therapeutic grade essential oils. There are only a couple of brands I would trust.

  10. Louise on

    I am very excited to try a number of your recipes which seem to have frankincense, ylang ylang, or myrrh. Can you recommend substitutes for each due to allergies? Which form of bentinite clay do you recommend, dry or liquid?

  11. Bri on

    Hi Dr Axe

    Just wondering how long this Remineralizing toothpaste will last? Do I need to store it in the fridge?


    • Nicole on

      Apparently the essential oil is different from the extract, I couln’t find a food grade one on amazon so I just omitted it and it tastes fine, I’m not sure what the benefits of it are, I added both bentonite clay and cacoa powder and it tastes like i;m brushing my teeth with chocolate.

  12. Nicole on

    When I use this my mouth feels a little funny afterward, I’m thinking it might be from the magnesium as the bottle had warned of potential itching or other discomfort, has anyone else encountered anything like this? It’s almost a slight swollen/tingly/burning feeling. It freaks me out a bit but I just spent almost $100 on all the ingredients, *though it’s going to last YEARS

  13. wolf on

    what about tea tree oil and aloe vera? they sound like wonders too for decay reversal tooth/bone remineralization and are used in ‘healthy alternative’ new stream toothpastes.

  14. Khan on

    Calcium Citrate and Magnesium Citrate are said to be more absorbent. Is this better to use them instead of Calcium Phosphate and Magnesium?

    • Dr. Josh Axe, DC, DMN, CNS on

      Hi Evelyn! You are absolutely correct. Thank you for pointing that out. Vanilla is not an “essential oil,” because it is not steam-distilled, expeller-pressed or cold-pressed. I have added a link to our article about vanilla oil for more clarity.

  15. Jennifer on

    Hello Dr. Axe!

    I am a frequent visitor of your website, and I just wanted to say thank you– your site has been such an awesome help to me this year!

    Your posts have been a constant source of guidance and knowledge that I needed all throughout this year as I have been going through a healing process. Because of your work, I have been able to make my own toothpaste, heal two cavities, make wise food choices, and overall become a healthier, and more conscious individual.

    I love the recipes you share, and the facts you provide for a variety of foods such as fish, vegetables and dairy. You have helped me become equipped to shop for healthier, less-processed, and non-toxic foods, and this makes me feel empowered and in charge of my health.

    Thank you for being a part of my healing journey and making it fun! May your new year be full of blessings, light and love!


  16. Jenn on

    Of all my searching for a good toothpaste and mouthwash I like this combination the best. My question is do you brush and spit in the trash because that coconut will clog your pipes? Is there a substitute for the coconut oil?

  17. Laurel on

    I love the toothpaste!!! I will never buy toothpaste again. Thank you Dr. Axe for sharing so much information and knowledge freely. I am deeply grateful. Blessings.
