Oral Galvanism

What is Oral Galvanism?


Galvanism is a battery effect caused by the presence of dissimilar metals in the highly conducive and acidic environment of the saliva of the mouth.  Dissimilar metals in the mouth include metal alloys combined to make mercury amalgams and metal alloys combined to create the metal substructure beneath the porcelain in a traditional lab fabricated crown (especially galvanic if there is an amalgam build-up beneath the porcelain-fused-to-metal crown).


Research suggests that galvanism may be disruptive to the electromagnetic functioning of the body.  It is an effect separate from and additional to any mercury poisoning that may occur in individuals who may not be able to bind and excrete mercury adequately for maintenance of general health. 


The symptoms listed below are NOT exclusive to galvanism/mercury poisoning, and their presence does NOT mean that you are suffering from galvanism or mercury poisoning. 


(NOTE: A person who no longer has teeth may still suffer mercury poisoning because the body stores mercury in tissues, glands and organs.) 


There is no way to predict, much less guarantee, whose health will benefit from amalgam removal.  We work with primary care providers, naturopaths, chiropractors, nutritionists, neurologists, and other health providers.  Even so, as dentists, we limit advice to the oral cavity and related bones, nerves, and musculature.  Always consult your health providers for health or medical concerns/questions.
