DIY Probiotic Toothpaste

Looking for an alternative to commercial toothpastes containing toxic ingredients that are harmful to your health? Here’s a natural and effective toothpaste you won’t have to call your doctor for in case you accidentally swallow some!

This homemade toothpaste may look more like dessert, but don’t be fooled!

Coconut oil and bentonite clay are the perfect foundation for toothpaste, creating a delightful taste and texture along with superior effectiveness.

Coconut oil supports the gut microbiome (remember that oral health is connected to gut health and that your mouth is part of your digestive tract).

Bentonite clay cleans your teeth without being too abrasive, while its high mineral content helps to remineralize your teeth.

The addition of probiotics and prebiotics help to create a healthy mouth flora. And as for the cacao…believe it or not it’s not just about the taste! (Although we here at Ask the Dentist do indeed love some high quality chocolate). Compounds found in cacao lower your chance of cavities and also harden tooth enamel.

Indulge in the naturally delicious flavor and satisfaction of brushing your teeth with healthy, non-toxic toothpaste that you made yourself!

DIY Probiotic Toothpaste

This recipe is made with cacao nibs, so it’s perfect for anyone with an affinity for chocolate. Cacao are the raw, beanlike seeds from which chocolate (as well as cocoa and cocoa butter) are made. And, as previously mentioned, cacao nibs contain compounds that promote the natural healing of cavities, in addition to providing a decadent, chocolate flavor. The addition of prebiotics and probiotics help to rebalance the oral microbiome, ensuring that new cavities can’t develop.

Here’s how to make it:

  • Author: Dr. Burhenne
  • Prep Time: 5 minutes
  • Cook Time: 10 minutes
  • Total Time: 15 minutes
  • Yield: 5-7 days for a family of 4 people (used twice a day) 1x



  1. In a small saucepan, heat coconut oil over low heat until melted, about 1 – 2 minutes.
  2. Add bentonite clay, baking soda, xylitol, prebiotic, probiotic, cacao, ginger and cinnamon to a food processor or high-speed blender and blend for 10-15 seconds until all powders are evenly combined, tapping sides and top of blender so powder will fall to the bottom.
  3. Wait a couple of minutes before opening to allow powders to settle, then pour one tablespoon of coconut oil into the blender. Blend for 10-15 seconds; mixture will be crumbly. Take the small end of a wooden spoon (a chopstick or small spatula will also work) and run it along the inside edge of the blender, making sure to combine all the powder with the oil.
  4. Add the vitamin E and remaining coconut oil, and blend another 10 – 15 seconds. A this point, the mixture will be runny. Again, run the wooden spoon end along the edge of the blender to make sure all the powder is incorporated. Blend again if necessary to create a smooth and creamy texture.
  5. With the blender running, slowly add the water and blend for at least 30 seconds, or until it is thoroughly mixed.
  6. Transfer to a glass container with a plastic lid or a nontoxic refillable squeeze tube.


Storage Tips & How to Use

Dip a clean spoon into the toothpaste and apply to your toothbrush. Store half at room temperature and use toothpaste within 7-10 days. Store the rest in the refrigerator for later use (it’s good for 4 weeks). Alternatively, fill a refillable squeeze tube with your toothpaste and squeeze about a quarter teaspoon onto your toothbrush twice daily for best oral hygiene. Store in your refrigerator for extended freshness.

    I’m wondering if you leave out the pre and probiotics would this be shelf stable?


    • Mark Burhenne, DDS says:

      Unfortunately not. Once you introduce water to the mixture, it will open up the door for bacterial growth.

  2. Patrick Webster says:

    Easier said than done. 🙂
    Where can a person easily find:
    4 tablespoons Food Grade Bentonite Clay
    1/2 teaspoon Baking Soda
    2 tablespoons Xylitol
    1/2 teaspoon Hyperbiotics Prebiotic Powder
    2 crushed capsules Hyperbiotics PRO-Dental

    • Mark Burhenne, DDS says:

      Hi Patrick,

      I have linked where I purchase mine from. Just click on the blue ingredient link!

  3. Is Bentonite going to be safe with metal (lead added) fillings? I’ve heard that it’s not and starts to break down the metal so that it can leach into your body. Please advise…

  4. Doctor, I live in South Africa. I don’t know what alternative I can use for the pre-and probiotics? We can buy probiotic capsules with prebiotics (some) – can I use those or what do you suggest? also, I think the ginger will wake me up, as I don’t really like it! can I use clove essential oil instead?

    Kind regards

    • Mark Burhenne, DDS says:

      Hi Johanita,

      I have some concerns about clove oil as it can kill the good bacteria you need in your mouth. Also, since I do not know of a specific brand of probiotic in South Africa, I would recommend reading the ingredients on Hyperbiotics PRO-Dental and see if you can find a similar alternative in SA. If you don’t find an “oral” version, you could empty a capsule into a glass of water and drink it to get the organisms in your mouth too.

      I hope this helps,

      Dr. B

    What about using these Receips with braces. That contain Bentonite clay? Is it unsafe?

  6. Hi Doctor,

    Thank you very much for the recipe!

    Can I skip the clay when making this recipe? I don’t mind the texture of my toothpaste being less “toothpastey” and more oily due to the coconut oil. I am just worried it has anti-cavities properties that are essential for a DIY toothpaste.

    Thank you once again!
