Approximately half of a dental amalgam filling is liquid mercury and the other half is a powdered alloy of silver, tin, and copper. Mercury is used to bind the alloy particles together into a strong, durable, and solid filling.he form of mercury associated with dental amalgam is elemental mercury, which releases mercury vapor. The form of mercury found in fish is methylmercury, a type of organic mercury. Mercury vapor is mainly absorbed by the lungs. Methylmercury is mainly absorbed through the digestive tract.
Fillings cost between $50 and $300 depending where you live, and the filling material (amalgam or composite) used. Dentists won't lose their jobs because they use mercury amalgams. contacted 1800 DENTIST.I had two fillings done in the last two weeks. I wanted only composite fillings, and it cost $170 per filling. I live in Northern Virginia where rent is relatively high. My insurance only paid 80% of the mercury filling, that is $86 (of $105).
