Silver-Colored Dental Fillings Contain Half Mercury

By Perry Mouncey

The gray metal plugs in our teeth are colloquially called “silver” fillings, but in fact contain 50 percent pure toxic mercury. This type of a amalgam filling was first introduced to dental consumers and 1812, and the modern version has changed little in 200 years. Today, in addition to the mercury, amalgam fillings are also composed of a combination of silver, copper, tin and zinc.

The U.S. Food and Drug Administration (FDA) and Health Canada certify the purity of each of the metals before they are amalgamated, or mixed together; but once mixed, the mercury amalgam filling is no longer certified by the FDA, Health Canada or the American Dental Association.

We have been told that these fillings are safe in our mouths, but current research shows a very different outcome. Mercury amalgam fillings release mercury vapor and particles with each bite, each swallow and each breath from the moment they are placed until the day they are removed. What then, is the effect on the body of chronic. low-dose exposure to poisonous mercury?

With even a single mercury amalgam filling, we are inhaling and ingesting mercury vapor (the most toxic form of mercury) on a daily basis. Over the years, mercury collects in our organs and tissues. The organs most frequently affected are the brain, heart, kidneys, liver, thyroid and adrenal glands; the G.I. tract also collects mercury.

There are three aspects of amalgam removal and replacement that must be addressed to ensure a healthy result for the patient. A heavy metal/mercury detoxification program is necessary to allow the body to excrete the mercury and other heavy metals we have absorbed over a lifetime and is most effective before, during and immediately after the mercury removal. Testing for heavy metals levels is available and an important aspect of the development of a personalized detox plan.

The dentist must use a safe, protective protocol when removing mercury fillings, which is not taught in dental school. The International Academy of Oral Medicine and Toxicology (IAOMT) provides training to interested dentists, as well as an excellent protocol for removal.

The most common replacement for amalgam is a white, resin composite filling. There are more than 1,000 brand names of composite materials on the market. Patients need to be sure that any material that goes into their mouth will be healthy, biocompatible match for their body. The use of materials reactivity test helps to determine the healthiest dental materials for each individual.
