I only had one removed. I have six or seven left that were replaced with new mercury fillings in my thirties. Sorry I didn't mention that. I went from mercury to mercury!!! Then a couple of years ago one filling needed replaced and I said no more mercury.
Barb those phone numbers on that website are wacky. That dentist listed for Bloomington has a Chicago area code. Then there's two dentists listed with my area code but I question that because they are not in my area.
