Most people recognize dental amalgams as silver fillings. Dental amalgam is a mixture of mercury, silver, tin and copper. Mercury, which makes up about 50 percent of the compound, is necessary to bind the metals together to provide a strong, hard, durable filling.
The facts on fillings: Amalgam vs. resin composite. You and your dentist have several choices when it comes to selecting materials to fill cavities. Among the choices are tooth-colored fillings made of resin-based composite and traditional dental fillings made of metal amalgam. Amalgam is more durable and less expensive than resin; however, resin fillings mimic the appearance of natural teeth, making them much less visible than amalgam fillings.
