Are These Medical Devices Too Dangerous? (Dental Amalgam)

Dental Amalgam

Dental Amalgam

Dental amalgam, a filling for cavities, can release low levels of mercury vapor that can be inhaled and has been associated with allergic reactions or sensitivities in some people, according to FDA. The material has been used for more than 150 years in hundreds of millions of patients, according to the agency.

Activists Say:

We believe that there is ample evidence to show that the mercury vapor released from amalgam fillings can cause numerous debilitating and costly health problems. In addition, it can contribute to, or make worse any existing health condition. Mercury is especially poisonous to the fetus, nursing baby, and young children.”

Industry Says:

... in its 2009 review of the scientific literature on amalgam safety, the [American Dental Association] 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.”
