U.S. FDA to re-examine metal dental fillings
U.S. health regulators are seeking a second opinion on whether mercury-containing dental fillings pose a risk to dental patients, especially children and pregnant women and if the dentists should stop using them.
The FDA in 2008 cautioned against their use in certain more vulnerable dental patients such as pregnant women and children, noting mercury’s risks and that a dentist should warn the dental patient against its use.
Mercury is a known toxin, and at issue is whether the vapors released from mercury in dental fillings are enough to cause harm such as brain or kidney damage.
While some experts and advocacy groups say mounting data show a clear link between mercury and side effects and that dental fillings are no exception, industry groups and dentists say other evidence shows dental amalgam is safe.
While it now backs these dental fillings, FDA has changed how it regulates them. Products must carry warnings against use in poorly ventilated areas or in dental patients with mercury allergies.
Another option for dental fillings is tooth colored composite material which most cosmetic dentists use.
