> Is it best to go ahead and get those fillings now? Probably, as far as your dental health is concerned. This is mostly untrue. Fillings don't last forever, so prematurely filling cavities "starts the clock" on the longevity of the filling. When the dentist is replacing a broken filling, the dentist has to remove more of the tooth. Eventually you will need a root canal and/or crown. So for maximizing your health, the dentist still has to make a judgment call on how early or late to fill. I say mostly because mercury amalgam fillings do seem like they can last effectively forever (20+ years), but they have fallen out of favor.
