Hi Timothy, You might want to consider your diet, as our teeth are built from our diet. Research Weston Price and his work regarding this subject. He has a lot to say on how the diet influences our teeth.

You can also do a search on youtube for Nadine Artemis who is an alternative health expert on re-growing tooth enamel. In the past I have posted quite a bit of video and audio of her speaking on this subject. If it's something you're interested in, let me know
Wishing you the best, Lisa
