Aim: The purpose of this paper is to summarize the research regarding the toxic health effects caused by mercury dental amalgams.

Method: The study involved summarizing scientific articles in journals regarding health effects of dental amalgam mercury.

Results: The science strongly suggests dental amalgam mercury may be an etiological factor in numerous health disorders. Mental health seems to be affected the most including such conditions as depression, anger, and irritability. Studies have also associated it with schizophrenia and bipolar disorders. The cardiovascular system also is affected including high blood pressure, heart rate, hemoglobin, hematocrit, and red blood cells. Subjects with amalgams have a decreased T lymphocyte percentage compared to a control, and the immunoglobins IgG, IgA, and IgE correlated with the number of amalgams. Myopia is reduced in amalgam bearing subjects but amalgam mercury is constricting the visual field. When comparing total health disorders of subjects with amalgams compared to those without, they suffered 45% more health disorders. Urine and hair mercury levels were significantly higher in subjects with amalgams compared to those without. The scientific evidence strongly suggests that amalgam mercury is associated with Alzheimer’s disease, multiple sclerosis, and amytrophic lateral sclerosis. Research has shown when amalgams are removed many health conditions improve.

Conclusion: The evidence is overwhelming that mercury from dental amalgam is an etiological factor in many health disorders.
