After meeting for two days on the issue, an FDA advisory panel has decided it can not decide whether mercury dental fillings are safe or harmful.
For decades, dentists have combined mercury with other metals to fill cavities. In light of concern that mercury could vaporize in the mouth and enter the blood stream, the use of mercury fillings has gone down significantly in the past ten years.
Most fillings today use Resin. Meanwhile, the panel says no study has found a negative effect from mercury fillings. In fact, the most recent research indicates there's no difference between Mercury and Resin. So, the panel's final recommendation to the FDA is more studies are needed.
