Alzheimer's disease, multiple sclerosis and immune dysfunction. Kidney impairment, neurological injury and mental illness. These are just a few of the possible liabilities stemming from mercury amalgam dental fillings. While orthodox dentists claim amalgams don't pose a long-term health threat, asserting that the mercury becomes inert once a filling has been set, the evidence of a causative role between amalgams and physical and mental disorders is overwhelming. A number of studies prove that mercury continues to leach from fillings due to the ongoing deterioration of the amalgam.

A variety of factors contribute to the corrosion of fillings, including the physical stress of chewing, the acidity and temperature of foods and beverages and the electromagnetic potential of other metals in the mouth. Dental amalgams contain not only mercury, but also silver, tin, copper and zinc. Crowns and bridges may contain these elements, as well as aluminum, beryllium, gold, iridium and nickel. Even the simple act of brushing your teeth can release mercury from an amalgam filling. The disturbing irony is that an activity done in the name of good hygiene can actually exacerbate poisoning.
