| http://www.w3.org/ns/prov#value | - A 2006 poll by Zogby International found that 72% of the more than 2,500 Americans surveyed were not aware of the levels of mercury in dental fillings.In addition to exposing the body to mercury during placement or removal of amalgam fillings, common dental procedures such as gum cleanings and root canals can force bacteria into the bloodstream, which may be harmful to some patients.
