The ADA Misinformation on Mercury
The American Dental Association continues to remain in denial about the toxicity of mercury. Dr. Murray Vimy is one of the leading mercury researchers and he has provided a detailed chronology documenting how mercury has been clearly established as a contributing factor for periodontal disease.
The news release by the American Dental Association (ADA) dated June 13, 2001 contains a very significant error. The ADA President Dr. Robert M. Anderton is reported as saying, “There is no sound scientific evidence supporting a link between amalgam fillings and systemic diseases or chronic illnesses.”
Yet this is well known in the published, peer-reviewed dental journals that mercury leaks directly from amalgam into adjacent oral tissues causing periodontal disease (gum disease).
Critical Fact #1: In 1957, Zander (JADA 55:11-15) reported “materials used in restorative dentistry may be a contributing factor in gingival disease.”
Critical Fact #2: In 1961, App (J Prosth Dent 11:522-532) suggested that there was greater chronic inflammation around amalgam sites than non-amalgam areas.
Critical Fact #3: In 1964, Trott and Sherkat (J CDA, 30:766-770) showed that the presence of amalgam correlates with gingival disease. Such disease was not present at contralateral amalgam free sites.
Critical Fact #4: In 1969, Sanches Sotres et al (J. Periodo. 140:543-546) confirmed Trott and Sherkat findings.
Critical Fact #5: In 1972, Turgeon et al. (J CDA 37:255-256) reported the presence of very significant erythema around amalgam restorations that was not present at control non-amalgam sites.
Critical Fact #6: In 1973, Trivedi and Talim (J. Prosth. Dentistry, 29:73-81) demonstrated that 62.5% of amalgam sites have inflammatory periodontal tissue reaction. Thus, as early as 1973, a case can be made that the presence of dental mercury-amalgam results in chronic inflammation and bleeding in the gingival tissue adjacent to it; in other words, in situ amalgam produced chronic Gingivitis.
Critical fact #7: In 1974, Freden et al. ( Odontol. Revy, 25:207-210) showed that gingival biopsy material from sites not adjacent to amalgam had 1-10 mcg mercury/gram of tissue (mean=3); whereas, gingival biopsy sites near amalgams contained 19-380 mcg mercury/gram of tissue (mean=147).
Critical Fact #8: In 1976, Goldschmidt et al. (J. Perio. Res., 11:108-115) demonstrated that amalgam corrosion products were cytotoxic to gingival cells at concentrations of 10-6: that is, micrograms/gram of tissue.
Critical Fact #9: In 1984, the year of the NIDR/ADA Workshop, Fisher it al (J Oral Rehab, 11:399-405) reported that at amalgam sites alveolar bone loss was very pronounced and statistically significant as compared to control non-amalgam sites! In other words, in situ amalgam produces chronic Periodontitis.
This suggests that placing mercury fillings leads to a dentist-induced disease, periodontal disease, which the same dentists then treat. This is iatrogenesis.
Thus, for the ADA to conclude “there is no sound scientific evidence supporting a link between amalgam fillings and systemic diseases of chronic illness” is incorrect.
Periodontal disease is one of the most prevalent chronic diseases in Man, and mercury fillings contribute significantly! Such statements by ADA spokespersons suggest that the ADA and its advisors may be knowingly disinforming the public through the media or they lack an understanding of the research about mercury release from amalgam published in their own journals.

DR. MERCOLA’S COMMENT:
Dr. Vimy is one of the top mercury researchers in the world and his comments to the ADA press release are most informative. You can review the article I published with Dr. Klinghardt earlier this year for further information on mercury detoxification.
Thanks to Jeff Green of Citizens for Health for sending this very interesting timeline regarding the dental use of mercury.
