But did you know that if you mix any two or more different metals in the mouth in the form of metal fillings with saliva, which acts as a conduit, an unnaturally high electric current will flow through your head? PLAY. This means that there is the possibility for electrical current to flow to or from that metal. Oral galvanism increases the process of corrosion and breakdown of amalgam fillings. Oral galvanism is a serious problem, especially when dissimilar metals such as mercury dental amalgam, along with titanium implants are placed in the oral cavity. sely04. Abstract – Fifty‐four patients referred to the Faculty of Odontology, University of Umeå, for investigation regarding “oral galvanism” were subjected to a general oral investigation. These dental restoration metals mix with saliva, which has an acidic pH, to create this effect.
