1. Mercury Fillings Leak
Exposure to mercury from fillings results from erosion of the filling, or from evaporation from the surface of the filling. In one study, using a variety of X-ray imaging technologies, scientists examined the movement of mercury through the tooth. They found mercury in the tooth several millimeters away from the site of the filling. They also found higher concentrations of mercury in the area of the tooth, which connects with the gum, suggesting exposure to the blood stream. It was also found in the tartar on the teeth. Conclusion? This stuff does not stay put!
