i actually have only 1 more amalgum to go for removal. the dentist is use is excellent and he uses good safety precautions. i have done some research, going to previous dentists and getting x rays. i believe that there is no silver under 2 of the 3 crowns. there is a titanium post though and the crowns are made of gold/porcelain. there may be silver underneath the 3rd crown. i don't know whether to have him check underneath. its probably a good idea since i want ALL the mercury out and for peace of mind. what are your thoughts on the likely hood of mercury under crowns? do dentists usually drill all the silver out before placing a crown? my understanding is some do, some don't.
