Traditional silver amalgam fillings may contain as much mercury as a thermometer. Many Americans still have silver fillings despite international recognition of the health risks associated with them. Simply removing silver fillings and replacing them with white composite fillings can improve long term health, especially for the immune system.
Comments by Dr. Ted Herrmann:
Dental amalgams are typically referred to as silver fillings because of their grayish-silver coloring. These metal mixtures contain various amounts of tin, silver, and worst of all mercury. The larger the filling, the higher the mercury content. Big fillings, in fact, may be composed of upwards of 50 or 60% mercury.
