Make Your Own Toothpaste
Michelle’s recipe:
2 tablespoons of organic coconut oil (relatively easy to find in a regular or organic food store and then a tablespoon of baking soda and then about twenty drops of the organic peppermint oil  We slightly melted the oil in the microwave to mix.
There are lots of recipes in which the ratio of coconut oil to baking soda varies (cela va su simple au double).  Best thing to do is try and see what you like best.
One can find bamboo toothbrushes at an organic store.

Another member just uses plain Baking Soda 3 times a week. (Alternating with commercial tooth paste that her dentist recommended to help reinforce her enamel.) She has a small jar and dips her toothbrush in it.  It’s salty. Some people might not like that.

Damien’s Powder Toothpaste:

1 tbsp sodium bicarbonate (baking soda)
4 tbsp finely  powdered white  clay (argile blanche)
½ tsp. table salt
2 drops lemon or mint essential oil

Place the powdered white clay in a sealable container. Mix in the sodium bicarbonate. Add the salt (if it is not fine enough, first grind it with pestle and mortar.) Add the essential oil drops and mix well.

In this recipe, the sodium bicarbonate is only used for its qualities as a whitener, whereas the salt is an antiseptic and fungicide. The white clay is used for its cleansing and anti-infection properties, the lemon essential oil as an antiseptic and bactericide, and the mint essential oil because it is an anti-infectant and gives one fresh breath! This powdered toothpaste easily keeps for one month.
