if something has to be treated as toxic waste when disposed of, why is it permanently inserted into peoples' mouths?
All fluids and matter removed from a patient in any clinical setting is considered biohazardous as dictated by OSHA.
The panel recommended that the FDA conduct further studies on the risks to children from dental amalgam, and that it consider a policy of informed consent for children and pregnant: that is, warning those groups of the risks associated with the fillings before installing them.
Part of the lawsuit centered on the FDA’s failure to respond to these recommendations in a timely fashion.
“This is your classic failure to act,” federal judge Ellen Segal Huvelle told the agency.
As part of the lawsuit settlement, the FDA must reach a final decision on the regulation of amalgam by July 28, 2009.
Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses. When amalgam fillings are placed in teeth or removed from teeth, they release mercury vapor. Mercury vapor is also released during chewing. FDA’s rulemaking (described in question 7) will examine evidence concerning whether release of mercury vapor can cause health problems, including neurological disorders, in children and fetuses.
Research on monkeys has shown that mercury released from dental amalgam restorations is absorbed and accumulates in various organs such as the kidney, brain, lung, liver, gastro-intestinal tract, the exocrine glands. It was also found to have crossed the placental barrier in pregnant rats and proven to cross the gastrointestinal mucosa when amalgam particles are swallowed after amalgam insertion or after removal of old amalgam fillings.

An excellent short subject video demonstrating the evolution of Hg vapor & the potential hazards of mishandling a spill. Note: the method used to visualize the Hg is very sensitive & exactly how much Hg is vaporized in the demonstration is not stated. (The visualization method is similar to that used in an atomic absorption spectrometer) A sincere thanks to Dave Heinlen Safety and Health Coordinator Bowling Green State University 102 College Park Office Building Bowling Green, Ohio 43403 for this video.
