Perhaps mercury is best known for its reputation for tainting the fish we eat. Warnings are consistently in the news about fish taken from the ocean, lakes and streams containing mercury and the potential health problems if eaten too frequently. Mercury continues to be linked to a number of health conditions and fatal diseases. Recent studies at the University of Kentucky show a high correlating level of mercury in the brain cells of Alzheimer’s patients.
Although it is still legal to use mercury in dentistry, there are enforced requirements regarding how to safely dispose of it. Dental offices are required to use safe filtration and disposals systems when discarding the material. Dental office waste is required to be filtered before being dumped in municipal sewage to help lessen the possibility of it becoming tainted with toxins. Again, the question of our safety arises. If special filtration is used to dispose of mercury, is it safe to be in our bodies at all?
Other metals besides amalgam don’t get a clean bill of health either. Heavy metals and other unsafe minerals that are found in dentistry, such as nickel, cadmium, aluminum, chromium and cobalt, are also considered toxic and can affect the immune system.
