The American Dental Association has reported that 100 million amalgam filling procedures are performed every year in the United States. However, since 2008, the use of amalgam fillings has been forbidden or restricted in Sweden, Norway, Denmark, and Germany. In addition, the European Parliament has adopted a ban on the use of amalgam in clinical practice for children younger than 15. Nevertheless, the use of dental amalgam fillings remains popular despite the controversy surrounding its potential effects on human health.
