Dental Amalgam in Anderson IN

Dental amalgam has been used by dentists for over 150 years. A mixture of metals that typically includes silver, copper, and tin, dental amalgam fillings (often referred to as silver fillings or metal filings) also contain mercury, occasionally raising safety concerns among patients.

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 the placement and removal of amalgam fillings does not cause adverse health effects.

Amalgam fillings remain a safe, cost-effective, and durable choice for restoring decayed teeth.

Frequently Asked Questions about Amalgam Fillings

Why is amalgam still used to fill teeth when composite materials are available?

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). This is often the case with teeth naturally subjected to extensive chewing force, such as molars. Mercury is an essential part of the amalgam mixture as it contains unique elements that allow it to be easily manipulated during placement and harden quickly afterward. In addition to longevity benefits, amalgam fillings are more affordable than composites.

What concerns are there with mercury and its effects on the body?

Mercury is a naturally occurring metal that we are exposed to in small amounts through water, air, and food throughout our lives. Excessive mercury exposure can negatively affect the brain and kidneys. However, it is crucial 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. Of course, if you prefer not to have an amalgam filling, Dr. Weiandt would be happy to discuss alternatives. 

What is the ADA’s position regarding the use of silver amalgam fillings?

A thorough summary of evidence ranging from 2004 to 2010 led the ADA to reaffirm its position that amalgam is a valuable and safe choice for patients.

When is it appropriate to use composite fillings?

Composite fillings are typically made of a resin and glass mixture, tinted to the color of your tooth, and commonly referred to as white fillings. They serve an essential purpose for teeth that are visible when smiling, providing an aesthetic benefit not afforded by silver fillings. While resin composite fillings undoubtedly look better than amalgam ones, they are generally considered less durable. Therefore, they may not be ideal for teeth subject to extreme chewing and biting forces. However, it is worth noting that 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 exposed to moderate pressure from chewing. It acknowledges that they are a good choice for a more natural-looking filling.

The bottom line

The ADA Council on Scientific Affairs has concluded that amalgam and composite materials are safe and effective for tooth restoration.
