to remove and replace restorations that aren't decayed and profit from it. Hal Huggins was shunned by the dental community for doing this exact thing.
Personally I don't see any justification for removing an amalgam restoration for no reason other than the mercury scare. Hundreds of millions of amalgam fillings have been placed with no measurable harm. Once a amalgam filling is in place it release mercury vapor at a slower rate than you would get from food. Some patients have had them in place for 70 years.
Sarcoplasm you are lecturing me, but you seem blind to the fact there is more than one way to look at it. In fact, I believe I am taking the ethical high road.
