Dental amalgam is a filling material that has been used by dentists for over 150 years. A mixture of metals that typically includes silver, copper and tin, dental amalgam fillings (commonly referred to as “silver fillings”) also contain mercury, which has raised safety concerns among patients from time to time.
In response to those concerns, the U.S. Food and Drug Administration (FDA), American Dental Association (ADA) and other organizations have conducted numerous studies over several decades and have repeatedly found that the small amount of mercury released during placement and removal of amalgam fillings does not cause adverse health effects.
Amalgam fillings remain a safe, cost-effective and durable choice when it comes to the restoration of decayed teeth.
While composite (or “tooth colored”) fillings are more durable than ever thanks to advancements in technology, there are still many cases where amalgam fillings perform better (and longer). Mercury is an important part of the amalgam mixture as it contains unique elements that allow it to be manipulated with ease during placement and then harden quickly after.
Mercury is a naturally occurring metal and one that we are exposed to in small amounts through water, air and food throughout our lives. Excessive exposure to mercury can negatively affect the brain and kidneys – however, it is important to understand that amalgam fillings do not cause dangerous levels of mercury exposure. Numerous scientific studies and thoughtful research have led the FDA to stand behind its position: amalgam fillings are a safe and effective restoration method for patients over 6 years of age.
A thorough summary of evidence ranging from 2004-2010 led the ADA to reaffirm its position that amalgam is a valuable and safe choice for patients.
The ADA Council on Scientific Affairs has concluded that both amalgam and composite materials are considered safe and effective for tooth restoration.
