I'm getting all the info I can on what removing all my amalgams would entail. If I have a large fillings under crowns, how will a dentist go about replacing that? Would he/she remove the amalgam and build up a new "post/stump" with the porcelain filling material then put a porcelain crown on top of that? If so, how stable would this be. If I have most of my molars crowned already, am I doomed to be sitting in a dental chair (a Hg free one of course) for the rest of my life, or will I eventually lose those teeth no matter what I do?

Thanks!
