2 parts baking soda, 2 parts coconut oil, 2 parts activated charcoal, 1 part turmeric or ground clove powder, peppermint essential oil (or any other essential oil) and/or liquid stevia to taste. You can also use clay powder for remineralization, just do 1 part clay powder and 1 part activated charcoal instead of 2 parts charcoal. It's really great for whitening teeth.
