Baking soda,dirt too: Toothpaste without Fluoride has no active therapeutic ingredient. Without "whiteners" it has no microabrasives. Other than taste, you can buy any expensive "all natural product" (with nothing of value in it) or you can use baking soda, dirt from your back yard, a slurry of oreo cookies or brush with nothing at all. It doesn't matter anyway good hygiene= floss =93%; toothbrush 6%; rinse 1%!
