Amalgam Fillings

Dental Amalgam is a dental filling material used to fill cavities caused by tooth decay. It has been used for more than 150 years in hundreds of millions of patients.

Dental amalgam is a mixture of metals, consisting of liquid mercury and a powdered alloy composed of silver, tim, and copper. Approximately 50 percent of dental amalgam is elemental mercury by weight.

Dental amalgam fillings are also know as "silver fillings" because of their silver-like appearance.

When placing dental amalgam, the dentist first drills the tooth to remove the decay and then shapes the tooth cavity for placement of the amalgam filling. Next, under approprate safety conditions, the dentist mixes the powdered alloy with the liquid mercury to form an amalgam putty. (These components are provided to the dentist in a capsule as shown in the graphics.) This softened amalgam putty is placed in the prepared cavity, where it hardens into a solid filling.
