Amalgam or “silver” fillings have been in use in some form for over 150 years. An amalgam filling is actually a mixture of mercury, silver, tin, and copper that bind together to form a strong, hard, and durable filling material. Amalgam is more cost-effective and stronger than its resin-based alternative, working very well in teeth that experience significant grinding and chewing (as in molars). Because of the mercury component, some individuals are concerned about the safety of amalgam fillings. Based on the best available scientific evidence, including clinical studies in adults and children ages six and above, the FDA considers dental amalgam safe for use by the general population.
