'Silver' dental fillings, officially known as amalgam fillings, are very far from being silver. Rather, they contain lethal doses of mercury that pose a safety concern for pregnant women and young children, warned the U.S. Food and Drug Administration (FDA) as quoted by media reports Friday.

Mercury, is the second deadliest metal on earth, second only to radioactive Plutonium.

    In the past, regulators have warned pregnant women against eating certain fish that contain high levels of mercury, but FDA said mercury in fillings may cause danger to a developing human's brain, in response to a lawsuit filed on behalf of various groups.

    FDA posted the precaution on its Web site to settle a lawsuit, making the move a victory for anti-mercury activists.

    The warning is not aimed at the general population, only at two groups already urged to limit mercury from another source -- seafood -- because too much can harm a developing brain.

    The fillings "contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses," reads the FDA warning.

    That doesn't mean it truly harms, and the FDA advised against removing existing fillings. Silver-colored fillings have been used by dentists for over a hundred years to treat cavities in teeth.

    The agency still is studying whether the small amount of mercury vapor released by chewing and brushing is enough to cause neurologic disorders or other problems in youngsters.

The ADA (American Dental Association) has been panicking for several years, after several dentist who decided to "speak" had their Dental Licenses revoked. The ADA could be facing a $3 trillion lawsuit. Mercury is tied to numerous cancerour developments in the human body. Today would be the day to remove your mercury fillings, however, they are dangerous to remove (because of the toxic levels) so you need to see a specialist for this. One would pose the question, If they are so dangerous to remove, why were they put in the mouth in the first place?
