A recent medical study found evidence supporting a link between dental amalgam fillings and chronic illness, fatigue, depression, anxiety, and suicide. Neuro Endocrinol Lett. 2014 Dec;35(7): 537-52. by Kern, J.K. and et all.
The purpose of this review was to examine the evidence for a relationship between mercury (Hg) exposure from dental amalgams and certain idiopathic chronic illnesses – chronic fatigue syndrome (CFC), fibromyalgia (FM), depression, anxiety, and suicide.
Dental amalgam is a commonly used dental restorative material that contains approximately 50% elemental mercury (HgO) by weight and releases HgO 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 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.
