You can use straight baking soda, but for the toothpaste aficionado, here is a great recipe.

2 tablespoons coconut oil
3 tablespoons baking soda
1/2 tsp Xylitol (non-GMO)
drops of peppermint oil to taste (I use around 10-15)


Mix it all together and store in a container in the bathroom.

**Xylitol actually prevents harmful bacteria from causing damage to the teeth and acts as a sweetener.**
