From Amalgam Myths and Facts (amalgam here means mercury-containing amalgams used by dentists):
Myth 10: Amalgam has been banned in Germany and Sweden and therefore should be banned in the United States.
Fact 10: Dental amalgam has not been banned in any country in the European Union.
From a 2009 press release:
The [Swedish] Government today decided to introduce a blanket ban on mercury. The ban means that the use of dental amalgam in fillings will cease.
In response to the Swedish ban, the American Dental Association put out a press release that said such a ban was “not necessary” in America because dentists do such a good job recycling the amalgam that doesn’t go into your mouth. Moreover, “a recent economic impact study published in the journal Public Health Reports indicates dental care costs in the U.S. would increase up to $8.2 billion in the first year alone if amalgam use was discontinued.” I don’t know what “up to” means. Perhaps it means that dental care costs would increase by a trivial amount “up to” $8.2 billion. Mercury-containing amalgam fillings are about half mercury.
