Should I Be Worried About My Amalgam Fillings?

In today’s Internet age, with a seemingly infinite amount of information available, it sometimes seems harder than ever to find a definitive answer to even a simple question. Health related matters are often the most widely covered subjects, which makes sifting through the various sources and opinions even more difficult. A perfect example of this is the controversy over the safety of amalgam fillings, used by dentists worldwide for more than one hundred years. The purpose of this article is to briefly discuss why the controversy exists and to provide some facts from authoritative sources.

Amalgam Overview

Amalgam fillings are composed of a powdered alloy, consisting primarily of:

  • Silver
  • Tin
  • Copper

This mixture is added to liquid mercury to bind the alloy particles together and form the amalgam, which is where the controversy begins. Ingesting mercury can cause multiple health problems.

The Controversy

Opponents of mercury-based amalgam fillings suggest that the mercury can leach from the filling into the body, causing mercury poisoning. Thanks to the Internet, the controversy has spread quickly and become a concern for many people. Dentists often receive requests to remove the fillings and replace them with another material. Though dentists often comply with their patients’ wishes, most dentists agree that the fillings pose no harm and removal is unnecessary.

Current Research and Opinion

Extensive research by governments and universities has revealed no negative effects caused by mercury amalgam. The U.S. Food and Drug Administration requires dentists to warn patients, but only due to possible allergic reactions and not possible mercury poisoning, The FDA considers the fillings safe for anyone age six and older. The Australian Dental Association’s official stance on amalgam fillings is:

“The ADA policy remains, on the basis of the research available, that the use of dental amalgam produces no harmful effects.”

Why Use Other Materials?

People often wonder why some dentists don’t use amalgam if they consider it safe. The simple answer is that other better materials are now available, such as white fillings.

Conclusion

As it currently stands, there’s no indication that amalgam fillings pose any health risk. The material is strong and long lasting, making it a good choice for many people. More and more dentists are moving away from the material, but usually not from fear of its toxicity, rather because modern materials offer other benefits.
