What Alternatives Are There To Mercury-amalgam Tooth Fillings?

          The jury is still out on the safety of mercury fillings, but most dentists now offer alternatives.

          Resin composites of powdered glass and epoxy-like materials match tooth color, and are now used for teeth in the front of the mouth. They work well for small cavities, but are not as durable as mercury amalgam. So many dentist prefer the latter for large, back cavities.

          Gold fillings and composites of porcelain are other options. But they are more expensive that mercury or resin. Porcelain costs twice as much as mercury and is likely needed to be replaced.

          Should adults have all of their mercury fillings removed? Most dentists do not advise this, unless you are having a problem with a tooth. The costly procedure is not usually covered by insurance -- and you increase your exposure to mercury when the old filling is chipped out. Still, many dentists suggest that children forgo mercury for composite resin fillings.
