Living in the far north of Australia I have noticed that most indiginous people and aspecialy the islanders have excellent teeth. (The ones that are not infiltrated by our diet). Most people of western culture that I know have dental decay and I wonder why. Is it only the sugar/acid aspect? Most of us have used tooth paste all their life and still have to spend a lot of $$ on keeping them intact. Have their been studies done on the damaging effects of modern dental hygine. Could it be that tooth paste makes teeth "addicted"? If not used constantly, could tooth paste have a long term damaging effect. Lawers need not reply.
