Not only is mercury vapor known to be released from dental mercury amalgam fillings at higher rates during brushing, cleaning, clenching of teeth, and chewing, it is the most toxic upon removal. When I had that one filling removed years ago, I was exposed to significant amounts of mercury vapors. All dental amalgam restorations contain approximately 50% mercury, and reports and research are consistent that these fillings emit mercury vapors. Scientific research demonstrates that dental mercury amalgam exposes dental professionals, dental staff, dental patients, and fetuses to releases of mercury vapor, mercury-containing particulate, and/or other forms of mercury contamination. etc. and mercury is also known to be released during the placement, replacement, and removal of dental mercury amalgam fillings. Bottomline, unsafe amalgam removal process releases mercury vapor and particles that can be harmful to the patient, the dentist, the dental staff, and the environment. This is why I am writing this 3 part series on amalgam removal: Part 1: Safe Amalgam Removal, Part 2: Detoxification Before and After Removal (this article), and Part 3: The Dangers of Heavy Metal Toxicity.
