Most scientific studies find no relationship between amalgam fillings and symptoms of mercury poisoning in any age group, although a small number of people have allergic reactions to these fillings.

Because mercury has long been recognized as poisonous to humans, concerns about the potential of mercury poisoning from dental amalgams have been addressed by abundant research. The choice of filling materials depends on the location of surface(s) to be repaired, how cooperative the patient is, and several other factors.ĭental amalgam fillings contain mercury and other metals. ĭental cavities are treated by drilling out the decayed material and replacing it with a filling, either an amalgam filling or one of the newer types of tooth-colored composite fillings. Untreated tooth decay leads to holes in the teeth (cavities), infections (abscesses), pain, and tooth loss. The result is acid which can erode dental enamel. Tooth decay begins when bacteria in saliva and plaque, a sticky substance found on gums and teeth, interact with sugars and starches in the diet. Centers for Disease Control and Prevention (CDC) reported that 41 percent of children had dental caries in their primary (baby) teeth and 90 percent of adults had caries in their permanent teeth. Most research finds no relationship between fillings and symptoms of mercury poisoning.ĭental caries (tooth decay) are pervasive. Do dental fillings containing amalgam ('silver fillings') cause mercury poisoning?
