Clay-based toothpaste

This toothpaste is comparable to the ones found in organic stores. With its 5 ingredients, it can be prepared in only 10 minutes.  It’s therefore an economical and efficient alternative to commercial toothpaste.


You may have already looked for toothpase recipes and been disappointed (no, honey is no good tooth paste and worse, it gives tooth decay. Even if honey has some antiseptic properties, sugars are the food for bacteria).

Let’s get back to basics ! After a meal, we gathered food bits around our teeth, mainly solubles in saliva. Even if we had no sucrose per se, as soon as the saliva enzyme starts degrading the complex sugars (starch, etc.), it releases sugar, which is the best food for bacteria causing tooth decay.

Our mission is therefore that the tooth paste:

  1. Cleans the remaining food bits, especially the sugars
  2. Limits the bacterial growth (associated with an acid feeling in the mouth, and smells…)
  3. Leave us with a good taste and smell!

Green or white clay have a mecanical action on the dirt, while water rinses it all off. The clay should be “surfine”, so as it does not damage the enamel.

Xylitol is excellent to prevent the bacterial growth, as it acts as a trap:  it’s absorbed by the bacteria which believe it’s sucrose but theycan’t metabolize it. They start storing it, keep starving and stop spreading around. Some people even use a 100% xylitol toothpaste! In addition, it brings the pleasant sweet taste that we’re used to. Sodium bicarbonate de contributes to reduce the acidity and therefore bacterial growth. Just a little is needed (if you really don’t bear the sensation it brings, you can remove it).

Finally, the mint essential oil brings a fresh smell, and can be replaced by green anise, lemon or clove.


Quantities are in % mass (measured with a scale). You can ajust according to for example the volume of your container, or the amount you need for 3 months. 50-100 grams should be enough for a first trial.

Here is how you need to proceed.


You’ll need: a cooking pot, a container (ideally glass or metal), a whip or an electric blender


  1. Leave the coconut butter melt in a hot-water bath
  2. Infuse water with mint leaves (or use directly a mint water)
  3. Meanwhile, separately mix the powders
  4. Add the powders (clay and bicarbonate) and the coconut oil
  5. Pour the hot water
  6. Strongly mix
  7. Leave it cool down before using

Note for the ones that are sensitive to texture, you can increase the amount of coconut oil.
