Evidence Supporting a Link between Dental Amalgams and Chronic Illness, Fatigue, Depression, Anxiety, and Suicide

Norway and Sweden have banned amalgam, reportedly due to environmental concerns. However, the use and toxic risk of dental amalgam fillings is still a subject of ongoing debate in many countries. Now, a review conducted by a team of international researchers has provided new evidence that mercury exposure from dental amalgam may cause or contribute to many chronic illnesses, as well as depression, anxiety and suicide.

The review article by Janet K. Kern and coworkers is published in Neuroendocrinology Letters (2014; 35 (7): 537-552). Three of the authors, Kern, Geir Bjørklund and Boyd E. Haley, are members of the Council for Nutritional and Environmental Medicine (CONEM). Kern is a director of CONEM. Bjørklund is founder and president of the association.

ABSTRACT

The purpose of this review is to examine the evidence for a relationship between mercury (Hg) exposure from dental amalgams and certain idiopathic chronic illnesses – chronic fatigue syndrome (CFS), fibromyalgia (FM), depression, anxiety, and suicide. Dental amalgam is a commonly used dental restorative material that contains approximately 50% elemental mercury (Hg0) by weight and releases Hg0 vapor. Studies have shown that chronic Hg exposure from various sources including dental amalgams is associated with numerous health complaints, including fatigue, anxiety, and depression – and these are among the main symptoms that are associated with CFS and FM. In addition, several studies have shown that the removal of amalgams is associated with improvement in these symptoms. Although the issue of amalgam safety is still under debate, the preponderance of evidence suggests that Hg exposure from dental amalgams may cause or contribute to many chronic conditions. Thus, consideration of Hg toxicity may be central to the effective clinical investigation of many chronic illnesses, particularly those involving fatigue and depression.
