My teeth seem to be 'falling' apart, large parts falling out to, for example, a packet of crisps, soft cheese, etc? The only reason for this, I can see is a build up of effects of my epilepsy medication over the years, although I have had epilepsy for over forty years? I have not changed my diet in nearly twenty years, [rather boring existence?] but these dramatic tooth decays have only really started about two years ago, large sections of teeth falling out, some seemingly perfectly healthy teeth, usually molars? I am sitting here now with about a third of the surface of a molar, that had had no dental work done on it in my sixty year lifespan.
