New study dismantles amalgam safety proposed by The Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR)


In a report to the EU-Commission the Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) stated “….no risks of adverse systemic effects exist and the current use of dental amalgam does not pose a risk of systemic disease,…” Widely published mercury researcher Joachim Mutter states, “SCENIHR disregarded the toxicology of mercury and did not include most important scientific studies in their review.” Mutter also dismantles the SCENIHR position in a newly published article in the Journal of Occupational Medicine and Toxicology, “Is dental amalgam safe for humans? The opinion of the scientific committee of the European Commission”

The real scientific data shows that:

a) Dental amalgam is by far the main source of human total mercury body burden. This is proven by autopsy studies which found 2-12 times more mercury in body tissues of individuals with dental amalgam. Autopsy studies are the most valuable and most important studies for examining the amalgam-caused mercury body burden.

(b) These autopsy studies have shown consistently that many individuals with amalgam have toxic levels of mercury in their brains or kidneys.

(c) There is no correlation between mercury levels in blood or urine, and the levels in body tissues or the severity of clinical symptoms. SCENIHR only relied on levels in urine or blood.

(d) The half-life of mercury in the brain can last from several years to decades, thus mercury accumulates over time of amalgam exposure in body tissues to toxic levels. However, SCENIHR state that the half-life of mercury in the body is only “20-90 days”.

(e) Mercury vapor is about ten times more toxic than lead on human neurons and with synergistic toxicity to other metals.

(f) Most studies cited by SCENIHR which conclude that amalgam fillings are safe have severe methodical flaws.


In addition the International Academy of Oral Medicine and Toxicology (IAOMT) issued a Critique on the SCENIHR Preliminary Report. Some of the points made were: The SCENIHR report is grossly inadequate as a scientific document and the report has serious omissions.

  • The report is contradictory.
  • The data that is reviewed is interpreted incorrectly.
  • The report confuses Toxicity and Allergy
  • It makes assumptions and forms opinions to draw unwarranted conclusions even with the very limited data it reviews.
  • The report ignores the synergistic effect of mercury with lead, the effects of gender, diet and certain antibiotics in increasing the uptake and toxicity of mercury from dental amalgam fillings.
  • The conclusion drawn by the committee that dental amalgam is an adequate dental restorative material is false and will be shown to be false in this document.

    If there was a Nobel Prize for quackery pseudoscience the SCENIHR report would be a prime candidate for it. Its wanton simple failure to mention just about all the evidence of harm while waffling away with distractions for 72 pages makes it a hostage to fortune, an own goal shouting out to all the world “look at us, see what charlatans we are!”
