Healthy Teeth. Healthy Body. No Mercury.

alt

Dental amalgam fillings, also known as silver fillings, is comprised of 45 to 55 percent mercury. Mercury is a naturally occurring element found in air, water and soil. It exists in several forms: elemental or metallic mercury, inorganic mercury compounds, and organic mercury compounds. Elemental (or liquid) mercury is the type of mercury used in dentistry.

Mercury is a neurotoxin and chronic exposure to it affects the nervous, respiratory, cardiovascular, and immune systems. All people are exposed to mercury in some form or another but certain sectors are more frequently exposed. This may be due to diet (certain seafood contain high levels of mercury) and/or occupation.

Mercury is known to bioaccumulate in people and animals that are chronically exposed. Some groups claim that the mercury used in dental amalgam fillings are so small that it poses no risks to health. However, the World Health Organization (WHO) states that even the minutest amount is harmful and can easily penetrate the blood-brain barrier, thus compromising the development of children in utero and putting children, pregnant women, and women of childbearing age at risk.

Several studies conducted by IAOMT revealed that patients with amalgam fillings are constantly exposed to mercury vapor as chewing, drinking hot beverages, and even brushing can cause mercury to leak into the saliva and into the bloodstream. Studies also show that mercury from amalgam fillings can increase the risk for allergies, MS, autism, and Parkinson's Disease.
