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, tin, and copper. Approximately 50% of dental amalgam is elemental mercury by weight.
Dental amalgam fillings are strong and long-lasting, so they are less likely to break than some other types of fillings.
The issue of safety of dental amalgam fillings has been a controversial topic in the news for quite some time.
The FDA, World Health Organization and the Center for Disease Control and Prevention have all reviewed the best available scientific evidence and determined that dental amalgam fillings are safe.
The ADA policy remains on the basis of research available that the use of dental amalgam has no harmful effects.
The choice of filling materials completely depends on the patient’s choice.
