A study has been done to compare the tooth strengthening of Theobromine, a compound derived from chocolate, with that of fluoride. The Theobromine came out better, increasing the size of the apatite crystals that form tooth enamel.
Theodent toothpaste has been developed, and is available at Whole Foods. They recently released a children’s chocolate flavored paste, and they carry a mint flavor.
I know a lot of you have concerns over fluoride (which I don’t share, but do understand), and this is an alternative. The best I have seen so far. It ain’t cheap!
