Composite fillings are typically made of a resin and glass mixture, tinted to the color of your tooth, and commonly referred to as “white” or “tooth-colored” fillings. They serve an important purpose for teeth that are visible when smiling, providing an aesthetic benefit not afforded by silver fillings. Composite materials continue to benefit from technological advancements, contributing to enhanced durability. The ADA supports composite materials in small or mid-size fillings on teeth that are exposed to moderate pressure from chewing, and acknowledges that they are a good choice for a more natural-looking filling.
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.
What is the ADA’s position regarding the use of silver amalgam fillings?
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 bottom line?
The ADA Council on Scientific Affairs has concluded that both amalgam and composite materials are considered safe and effective for tooth restoration.
