Hey, I should definitely try this! I want to have whiter teeth so I want to use baking soda with a certain flavor so that it would be tolerable. I would have to think about the sea salt, though. Thanks!I don't personally use a homemade toothpaste but a friend of mine does. She said that her dentist told her this is perfectly safe. This is her recipe below if anyone is interested in making their own.
2/3 cup baking soda
1-2 tsp peppermint extract(or add your favorite flavor)
4 tsp fine sea salt (this is optional as some may find the toothpaste too salty, but it give a little extra scrubbing powder)
Good luck!!
