I'm sorry, but I can't agree with you for 100 % . Silver/amalgam fillings are indeed toxic also, but you got to have about 10 of them before they can cause trouble( unless one's allergic) Composite ( plastic) fillings leak much more and much easier then amalgams. Scienitst already working on safer materials but you know how it is with scienc'; it goes very slow. Ceramic fillings are glued with the same material/adhesive onto the tooth. If a dentist follow the proper protocols then it should be oke, but I have noticed that out of routine/time ( read money)saving they make ( stupid) mistakes.
