"The U.S. Environmental Protection Agency announced a proposal to eliminate mercury pollution from dental offices nationwide.
These new Clean Water Act standards would cut discharges of dental amalgam – a mixture of mercury and other metals that dentists use to fill cavities.
Under this proposal, dentists must use devices to remove mercury and other toxic metals before they go down the drain."
