the dangers of amalgam is all over the net yet most dentists use the poison, if i were a dentist i would research it because i care. this is not a conspiracy i dont think on their part but at the begginning of the amalgam invention it was known of the dangers but they carried on using it because it would make us ill and the good thing is symptoms may not happen straight away so you wouldnt blame it on your dentist, its very clever stuff.
