Now, nearly 150 years after its founding—and in the midst of its third "amalgam war"—the ADA is trying to kill the debate for all time: It has amended its code of ethics to condemn the removal of serviceable mercury fillings as unethical, if the reason is to eliminate a toxic material from the body and if the recommendation is made solely by the dentist.

According to Professor Vimy, the ADA considers a dentist ethical if he places the poisonous substance and recommends its safety. However, if he suggests that mercury fillings are potentially harmful or that exposure to unnecessary mercury can be, he is acting unethically. Serviceable mercury fillings can be "ethically" removed if clone for aesthetic reasons, at the request of the patient (without prompting) or a medical doctor. In 1967, the inaugural issue of Environmental Research magazine featured "Mercury-Blood Interaction and Mercury Uptake by the Brain After Exposure," the research of L. Magos. His experiments with mice indicated that inhaled mercury reaches the brain.
Mercury amalgam continuously gives off vapor, and, inhaled, it has an incredibly high absorption rate—between 70 and 100 percent! Once in the brain, mercury oxidizes into its elemental form. Then the blood-brain barrier, designed to protect the brain from foreign substances in the blood, works against its own purpose, preventing the removal of the toxic metal from the brain.
Nonetheless, in 1976, the FDA pronounced its "acceptance" of mercury amalgam, since "it had been in use since 1840." It was added to the Generally Recognized As Safe (GRAS) list of pre-1930 drugs.
In 1979, perhaps as a reaction to the FDA ruling, research began appearing which documented that mercury vapor is constantly released from fillings, especially when they are stimulated by chewing, brushing or temperature shifts (such as drinking a hot liquid). Every time someone with amalgam fillings eats or brushes his teeth, the leaching of mercury into the body peaks. Afterwards, it takes almost 90 minutes for the vaporization rate to decline to its previous level.

Also, the greater the number of fillings and the larger the chewing-surface area they occupy, the greater the toxic exposure.

Since hot liquids also increase vaporizing, individuals with amalgam fillings who frequently drink tea or coffee run a higher risk of mercury-related pathologies.
The average person, with eight biting-surface mercury fillings, is exposed to a daily-dose uptake of about 10 mcg (micrograms) of mercury from his fillings.
12
Some individuals may have daily doses 10 times higher (100 mcg) because of factors that exacerbate mercury vaporization, such as more frequent eating, chronic gum chewing, chronic tooth grinding (usually during sleep), chewing patterns, consumption of hot or acidic foods and drinks, and mouth acidity.

Furthermore, Professor Vimy asserts the concentration of mercury in the brain correlates with the number of fillings present. In 1980, the World Health Organization (WHO) admitted, "The most hazardous forms of mercury to human health are elemental mercury vapor and the short-chain alkyl-mercurials."

By 1984, autopsy studies were published that demonstrated that the amount of mercury found in brain and kidney tissue directly relates to the number of mercury amalgam fdlings in the teeth. Research at the University of Calgary School of Medicine demonstrated that mercury from dental fillings could be found in the blood and tissues of pregnant
mothers and their babies within a few days of insertion.

SCIENTIFIC "TRUTH"—WHO'S RESPONSIBLE?
As the existence of the ADA has gradually become integrated into the public's awareness, the perception has grown up that its statements represent scientific truth. The association and its members know that a conditioned and ignorant public will rarely question any statement it makes. Thus, when it issues false statements that jeopardize public health, such as recommending that deadly toxins be placed in the body, it is party to a criminal act. Having third-party dentists do the dirty deeds does not excuse the association, especially since its members have spent years and much money studying in ADA-approved schools, and anyone who bucks the system risks his license, his income and his career. This constitutes extortion and racketeering by the ADA, punishable under the RICO Act.

DISCOVERIES AND REVELATIONS IN THE 1990S
1990—On December 16, CBS's 60 Minutes did a major story on the amalgam issue that generated the second-highest response for additional information in the history of the program. Most viewers thought it would produce a change in the system. Instead, the ADA launched a vast campaign to counter the knowledge 60 Minutes had r i v e n the public.
First, the ADA and "responsible" government agencies invested huge sums of money: They sent special letters and news releases to every dentist in the United States discrediting the scientific information presented on the program and assuring the dentists that amalgam had been used for 150 years so it must be safe. They also sent press releases to all the major media and even created a special program for dentists entitled "What To Tell Your Patients When They Ask About Amalgam."
Also appearing in 1990 was the first controlled research on the effects of amalgam implants. It cited significant effects of mercury amalgam on various tissues and organs in experiments with monkeys and sheep.
1991—Sweden banned the use of mercury amalgam implants.
In March, the FDA recommended "further studies," and consumer groups and legislators began introducing informed consent legislation whereby dentists would be required to inform patients of the content of amalgam fillings (implants) and the potentially harmful effects of mercury.
In May, a medical research team at the University of Kentucky established "a probable relationship of mercury exposure from mercury-amalgam fillings to both Alzheimer's disease and cardiovascular disease." University of Georgia microbiologists determined that mercury from fillings inhibits the effectiveness of antibiotics.
The WHO reported that exposure to mercury from amalgams is higher than that of other environmental sources and that each amalgam filling releases from three to seventeen micrograms of mercury daily during eating alone. The WHO audited all available scientific data on the subject and concluded that mercury from dental fillings is the greatest source of human exposure, exceeding intake from fish by about 200 percent.
1993—The International Academy of Oral Medicine and Toxicology (IAOMT) developed a certification program for biocompatible dentistry [using materials compatible with each patient's body chemistry]. Dentists certified by the IAOMT will have "demonstrated proficiency in replacing amalgams safely and properly."
Swedish researchers discovered that gastrointestinal function improves after amalgam is removed. A citizens' petition requesting a ban on the use of amalgams was filed with the FDA.
The State of California passed a law requiring the Board of Dental Examiners to develop, distribute and update a fact sheet describing and comparing the risks and efficacy of the various types of dental restorative materials. Prior to this, a dentist risked losing his/her license for giving such detailed information to a patient. Presenting both sides of the dental mercury issue to a patient was considered unethical!
1994—In January, the government of Ontario demanded a probe of mercury dental fillings. In February, Sweden announced a total ban on the use of mercury amalgam fillings.
BBC'S "PANORAMA" PANS AMALGAM
On July 11, 1994, the British BBC-1 documentary program Panorama focused on the amalgam controversy. Dr. Lars Friberg, chief advisor to the WHO on metals poisoning, told Panorama, "The use of mercury in dental fillings is not safe and should be avoided." The program also reported on new scientific research which demonstrated clear links between the mercury released from dental fillings and serious illness, including Alzheimer's disease.
Dr. Friberg told Panorama that he "did not know why" the British Dental Association considers mercury levels in amalgam "safe" and that he thought, "They are wrong." He was concerned particularly about deposition of mercury from fillings into the brains of children.
According to Dr. Friberg,
[W]e know that children are especially vulnerable to the amalgam. We know that it takes a few years after birth until the brain is developed, and we know the brains in children are much more sensitive than those of adults. I think that you should try to avoid the implantation of toxic metals in the mouth. There is no safe level of mercury, and no one has actually shown that there is a safe level. I say mercury is a very toxic substance. I would like to avoid it as far as possible.
