i have a fair number of amalgam fillings, all from the same kindly dentist, from my pre-teen years as a soda junkie. i am now 49 and the only filled tooth that ever broke was a filling i got as an adult. in fact that tooth broke a second time and required a root canal.
a few years back, there was a "shadow" of a cavity on an x-ray, but my dentist is holy-hell expensive and he said it could wait. HA! since going primal and switching toothpaste it's GONE!
i think dentists are just trained that teeth corrode and fail, and for the most part, for those eating SAD, that is very true.
i don't have an answer about finding a good dentist, but sb makes a great point. if you have access to a dental school, they may take you in for very little $$$. i have tons of friends who go to tufts dental school clinic here, because it's one of the best dental schools in the us and obvz, not for profit, so cheap.
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
