I've not used "toothpaste" for years. The glycerin in toothpaste, EVEN IN NATURAL BRANDS!!, blocks the pores of your teeth, preventing remineralization (blocked pores are bad. Really).
I do, however, use a few of "Uncle Harry's" tooth products, like the tooth powder, and the tooth and gum elixer oil (oil of peppermint and, um, something else). And, a waterpik. I love my waterpik.
