Are Amalgam Fillings Safe?

In recent years, silver-colored fillings, known as amalgams, have become a controversial topic. Some people believe they are responsible for diseases such as autism, Alzheimer’s, and multiple sclerosis due to the presence of mercury.


Mercury can be a toxic substance, however when it is mixed with other metals such as silver, copper, tin, and zinc, it forms a stable alloy. Dental amalgam fillings have been used for over 150 years to preserve hundreds of millions of cavities.


The American Dental Association (ADA), the Federal Drug Administration (FDA), and numerous public health agencies agree there is no proof that these fillings cause harm to consumers. What’s more, there’s no solid scientific evidence that a person is cured of these or other diseases upon removal of dental amalgam fillings. The cause of autism, Alzheimer’s disease, and multiple sclerosis remains unknown. Nevertheless, Norway, Denmark, and Sweden have banned it’s use, mainly for environmental concerns.


In 2008 a lawsuit was filed by consumer groups and individuals troubled over mercury exposure. To settle the suit, the FDA agreed to update its web site on the matter. Current FDA info on dental amalgam fillings can be read here.

If dental amalgam still gives you qualm, there are multiple alternative options to consider.
