This toothpaste is similar to those found in organic stores. With its 5 ingredients, it can be prepared in only 5 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, while water rinses it 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 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 or completed by green anise, lemon or clove.

Note on clays: The green clay (illite or montmorillionite) was formed under temperate, alkaline pH; its color is due to the diversity of minerals that it comprises. Whereas the white clay (kaolinite) was formed under warmer, more acidic pH, and comprises only hydrated aluminum silicates. The green montmorillionite is more absorbant while kaolin is not. Montmorillonite is therefore easier to handle (kaolin tends to floculate – become crumbly when too hydrated). It can also be used to make facial masks, as it as “purifying properties”: it will capture the pollutants from the skin (metals, and other organic compounds) and also the fats (it leaves the skin “nude” – which is a type of aggression, this is why facial masks should be appliednot more than once-twice a weak).  The optimal final texture may be hard to fine-tune, as it is very sensitive to the water content. We want to avoid crumby textures… So a little bit of water can be added initially in the clay to hydrate it and give a plastic toothpaste-like texture. Note that with both types of clays, the preparations will slightly harden over time… Adding a few drops of water will give it back its initial texture !



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. 100 grams are a good amount for a mensual preparation.

Here is how you need to proceed.



You’ll need: a cooking pot, a container (ideally glass or metal), a fork or spatula, a spoon


  1. Leave the coconut butter melt in a hot-water bath
  2. Meanwhile, separately weigh and mix the powders : clay and bicarbonate
  3. Add the powders into the coconut oil and mix with a fork or spatula
  4. Pour in a small container and leave it cool down before use
