of amalgam has not changed despite the phasing-down in some countries. North America In the United States, numerous respected professional and non-profit organizations consider amalgam use to be safe and effective and have publicly declared such. In addition to the American Dental Association, other American organizations, including the Mayo Clinic, the U.S. Food and Drug Administration (FDA), Alzheimer's Association, American Academy of Pediatrics, Autism Society of America, U.S. Environmental Protection Agency, National Multiple Sclerosis Society, New England Journal of Medicine, International Journal of Dentistry, National Council Against Health Fraud, The National Institute of Dental and Craniofacial Research NIDCR, American Cancer Society, Lupus Foundation of America, Consumer Reports and WebMD have all given formal, public statements declaring that amalgam fillings are safe based on the best scientific evidence. On 28 July 2009, the U.S. Food and Drug Administration (FDA) recategorized amalgam as a class II medical device, which critics claim indicates a change in their perception of safety.

Despite the research regarding the safety of amalgam fillings, the state of California requires warning information given to patients for legal reasons (informed consent) as part of Proposition 65. This warning also applied to resin fillings for a time, since they contain bisphenol A (BPA) a chemical known to cause reproductive toxicity at high doses. In Canada, amalgam use is considered safe and effective by some groups. A 2005 position statement from the Canadian Dental Association (CDA) states "current scientific evidence on the use of dental amalgam supports that amalgam is an effective and safe filling material that provides a long-lasting solution for a broad range of clinical situations. The CDA has established its position based on the current consensus of scientific and clinical experts and on recent extensive reviews of strong evidence by major North American and international organizations, which have satisfactorily countered any safety concerns." Amalgam use is regulated by Health Canada as are all medical treatments and Health Canada has also stated that dental amalgam is not causing illness in the general population.
