Oral
Galvanism
To make a
battery you need two or more dissimilar metals in a liquid
medium. This battery effect can occur in the human mouth with
the placement of dental fillings. The amalgam fillings, which
normally contain silver, copper, tin, and zinc, provide the
dissimilar metals, and the saliva provides the liquid medium.
These elements produce electrical currents in the mouth called
oral galvanism.
Oral galvanism increases the process of corrosion and breakdown
of amalgam fillings. These electrical currents increase the
amount of mercury vapor and abraded particles released into the
mouth. Oral galvanism also causes the release of free-mercury
droplets from the filling. Furthermore, this electrolytic
process is exacerbated when gold crowns or other metall content
bridges, overdentures are in contact with mercury fillings.
In addition to amplifying the process of corrosion and the
release of mercury into the mouth, scientific evidence exists
that these internal electrical currents can cause unexplained
pain, ulcerations, and inflammation in susceptible individuals.
