Oral galvanism or amalgam disease was a term for the association of oral or systemic symptoms to either: toxic effects of amalgam fillings; or electric currents between metal in dental restorations and electrolytes in saliva or dental pulp.[1][2][3] Any existence of galvanic pain or association of either currents or mercury to presence of symptoms has been disproven.[2][1] Beyond acute allergic reaction amalgam has not been found to be associated with any adverse effects.[4]
Very weak currents have been measured in the mouth of those with multiple dental fillings consisting of different alloys, but there was no association between presence of current and symptoms,[1] and any symptoms associated with currents between oral fillings are likely to be psychosomatic in nature.[2] No association between presence of mercury and symptoms have been found, with symptoms likely to be psychosomatic in nature and do not improve with chelation therapy.[1][3][5] Claims of causing a variety of symptoms such as oral discomfort, skin irritation, headaches and a metallic taste in the mouth have been discredited.[1]
The condition was originally proposed in 1878,[6] and became well known in Sweden during the 1970s and 80s, because of a campaign to educate about and replace oral amalgam fillings with mercury with other compounds such as ceramic or polymer restorations.[1]
