All silver fillings actually contain over 50% mercury. They are also called amalgam fillings. Mercury is a heavy metal that has known toxic effects on the human nervous and immune systems and it is slowly released over time from amalgam fillings. Dr. Bennett places no mercury amalgam fillings in anyone’s mouth. There are many high quality mercury-free dental materials which can be used as an alternative to mercury amalgam when patients desire to have their fillings replaced. Dr. Bennett follows the IAOMT protocol for safe removal of mercury amalgams. He protects himself, his staff, and the patient in the removal of any mercury amalgam fillings.
