German Research
German-speaking researchers have produced some of the most thorough government and academic work on dental mercury. This is what it found, and what the academy takes from it.

The Most Studied Material In Dentistry
No dental material has been examined as closely as amalgam. Much of that work was done in Germany, where the federal health authorities, university clinics, and independent institutes studied mercury release, human tissue burden, and individual susceptibility over decades.
The value of this body of work is that it was produced by institutions with no stake in biological dentistry. The academy did not commission it, and it does not need to: the findings speak for themselves.
What The Research Found
The German Amalgam Assessment
The German federal health authorities commissioned a comprehensive assessment of the dental amalgam literature, producing one of the most thorough government reviews of the material. It concluded that amalgam releases mercury and that certain individuals are more susceptible to its effects, while stopping short of a general ban.
What It Means
Even the body that declined to ban amalgam accepted that it releases mercury and that susceptibility varies between people.
Urinary Mercury And Filling Burden
German and other European studies measured urinary mercury excretion against the number and surface area of amalgam fillings, and against fish consumption. Filling burden consistently showed up as a predictor of excretion.
What It Means
Mercury from fillings is measurable in the body, and more filling surface means more excretion.
Genetic Susceptibility
Research groups in Germany and elsewhere examined polymorphisms affecting mercury handling and detoxification, looking at why two people with similar exposure can respond very differently.
What It Means
There is a scientific basis for treating material choice as an individual question rather than a population average.
Mercury In Organ Tissue
European autopsy and biopsy studies examined mercury concentrations in kidney, brain, and other tissue, and related them back to dental status during life.
What It Means
The mercury does not stay in the tooth. It distributes into tissue, and dental status is part of the picture.
