Why do you use tooth-colored composite fillings?

Return to FAQs

Our Elk Grove dental office recommends tooth-colored composite restorations for fillings. Tooth-colored composite fillings have a number of advantages over older amalgam (often called "silver") fillings.

Tooth-colored fillings blend in perfectly with the natural color of your tooth while amalgam fillings leave dark shadows on your teeth. If amalgam filling has been used in root canal therapy, the entire tooth can become discolored. Composite fillings give you a restoration that is virtually undetectable.

Like any other metal, amalgam fillings expand and contract in response to changes and temperatures, which can eventually cause the tooth to crack or the filling to “leak,” leading to recurrent decay. Composite fillings do not do this. Unlike amalgam fillings, composite fillings bond to your tooth, which means that they can make the tooth more structurally sound.

Tooth-colored composite fillings are mercury free, which many people prefer. It is important to note that while some people worry about the fact that amalgam fillings contain mercury, multiple studies have shown that the mercury in amalgam fillings is not dangerous, and no cases of mercury poisoning have ever been linked to amalgam dental fillings.

If you have further questions about composite fillings or have older amalgam fillings that you would like to replace with tooth-colored composite fillings, call our office to schedule an appointment.
