Seafood and Dental Fillings
This liquid metal had gained attention in the 1970s over the risks of its exposure. Mercury is a natural element that occurs in different forms, including metallic, inorganic, and organic compounds. Although it is used in various products, like dental fillings, mercury is also toxic and poses a threat to human and environmental health. Contaminated seafood, particularly large predatory fish such as tuna, swordfish, and shark, is one of the most common sources of mercury exposure for humans.
Dental amalgam fillings, which consist of mercury, silver, tin, and copper, have caused controversy due to concerns about the potential health effects of mercury exposure. The American Dental Association asserts that dental amalgam fillings are safe. Some studies suggest that prolonged exposure to mercury from these fillings may have adverse health effects, mostly on neurological health. Meanwhile, mercury exposure from contaminated seafood can also lead to serious health effects, especially on the development of children. To reduce exposure to mercury, pregnant women and young children are advised to avoid consuming certain types of fish and limit overall seafood consumption.
