“Silver” amalgam fillings are 50% mercury. The mercury in the filling is not locked in and releases a vapor, when there is a temperature rise. The mercury is inhaled and is readily absorbed in the bloodstream. The effects of this constant inhalation are cumulative. The World Helath Organization has concluded that dental fillings contribute more mercury to a person's body than all other sources combined.
