My teeth are in relatively good repair, I only have two fillings but I have a different problem - the teeth are starting to just fracture & pieces fall off. I'm nearly 49 for reference. Never smoked if that makes a difference, clean healthy diet. I've just eaten a piece of toast crust & it seems one corner of a back tooth has fallen off. This happened on the lower jaw also only two months ago. I don't want to be one of those grannies with awful teeth.. What can I do? I already brush regularly/floss & mouthwash.
