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.
Amalgam â This is a mixed filling made up of silver, tin, zinc, copper and nearly 50% mercury. Amalgam lasts about 10 years and is the least expensive dental replacement filling. The average cost for amalgam fillings is between $110 to $200 per filling. Composite resin â This filling is made of plastic and glass, lasting up to five years. It is more expensive than amalgam, but matches the color of your child's teeth. Treatment can be completed in only one visit to the dentist.
