my insurance paid for about 75 % of the removal/ replacment last year when I had my 9 amalgams removed ,the dental insurance company did not ask why I was removing them and I left it at that , I was lucky to find a dentist In my area that knew how to remove them safely ,as for a doctor I think that It would of complicated matters for me with the dental insurance company , plus I live in a small town and all doctors in this area are traditional and don't believe in mercury piosoning from fillings , I had to pay a little extra about 20.00 per tooth for composite fillings
