This hearing will examine the environmental risks of mercury in dental fillings (known as dental mercury amalgam) and the government’s regulatory response to it.

Dental offices are the third-largest user of mercury in the United States. Mercury contained in the existing dental fillings of Americans comprises over half of all mercury in use today, amounting to more than 1,000 tons. According to the U.S. Environmental Protection Agency (EPA), “Mercury discharges (in wastewater) from dental offices far exceeded all other commercial and residential sources.” These discharges may have a significant negative effect on the environment. Sludge, the mercury-contaminated byproduct of municipal sewage treatment plants, is often incinerated, causing the formation of “methylmercury,” the most toxic and dangerous form of mercury.

EPA’s only dental mercury-specific program is an educational program to encourage new dentists to use equipment to prevent mercury from entering the wastewater.

Mercury dental devices are regulated by the Food and Drug Administration (FDA), but FDA has never conducted an environmental assessment of the use of dental mercury amalgam as prescribed by law.
