“The U.S. Food and Drug Administration today issued a final regulation classifying dental amalgam and its component parts – elemental mercury and a powder alloy—used in dental fillings..."

The American Dental Association (ADA) agrees with the U.S. Food and Drug Administration's (FDA) decision not to place any restriction on the use of dental amalgam, a commonly used cavity filling material.

The FDA ruling issued today categorizes encapsulated dental amalgam as a class II medical device, placing it in the same class as gold and tooth-colored composite fillings. The ADA has supported a class II designation for dental amalgam since 2002 when first proposed by the FDA.

"The FDA has left the decision about dental treatment right where it needs to be—between the dentist and the patient," states ADA President Dr. John Findley. "This decision underscores what the ADA has long supported—a discussion between dentists and patients about the full range of treatment options to help patients make educated decisions regarding their dental care."

Dental amalgam is a cavity-filling material made by combining mercury with other metals such as silver, copper and tin. Numerous scientific studies conducted over the past several decades, including two large clinical trials published in the April 2006 Journal of the American Medical Association, indicate dental amalgam is a safe, effective cavity-filling material for children and others. And, in its 2009 review of the scientific literature on amalgam safety, the ADA's Council on Scientific Affairs reaffirmed that the scientific evidence continues to support amalgam as a valuable, viable and safe choice for dental patients.

"Dentists are doctors specializing in oral health care," Dr. Findley states. "We encourage people to talk with their dentists if they have any questions about their oral health."
