Oral galvanism is claimed to occur when two or more dissimilar metals in dental restorations which are bathed in saliva, or a single metal in contact with two electrolytes such as saliva and pulp fluid tissue, produce an electric current.[dubious – discuss][1] when associated with pain, the term galvanic pain is used.
The hypothesized electric current is claimed to cause a variety of immediate symptoms in some people, such as oral discomfort, skin irritation, headaches and a metallic taste in the mouth.[2] The galvanism can affect immune levels[3] and the trigeminal nerve, causing a variety of other symptoms, such as insomnia, vertigo, and memory loss.[4] The condition is idiopathic, depending on the individual’s state of health.[5] It has varying effects on oral microbial communities.[6] It was first proposed in 1878.[7] Oral galvanism can usually be reduced or eliminated by replacing metallic amalgam restorations with ceramic or polymer restorations.
