What are Composite Filings Made Of?


Posted on 8/10/2018 by Thomas Mahar
What are Composite Filings Made Of?If you have a cavity, it will need to be filled. In the past, the only choice was to use the silver fillings, even for front teeth.

You may have a parent or elderly relative that still has those fillings in their mouth. With modern advancements, patients have another choice when it comes to fixing a cavity. Composite fillings, the white kind of material that makes any dental work look more natural.

What is Composite Resin Made Of?

A composite resin is made of a plastic and glass mixture that dentists use to restore a tooth affected by decay. They are also used in other dental cosmetic procedures to improve the appearance of teeth damaged by stains or those who have imperfections such as a crack or chip.

Are Composite Fillings Safer Than Silver Fillings?

While many people still believe that silver fillings are dangerous because of mercury exposure, studies have all but debunked those fears and the silver fillings are still an approved method used in dentistry. Even though, composite fillings are very popular because they can be made to match the color of your natural teeth, some patients are concerned about exposure to certain materials used in some kinds of composite, specifically BPA.

Is There BPA In Composite Fillings?

BPA stands for Bisphenol-A, a chemical that acts like an estrogen and is used to produce certain plastic products, such as reusable containers, plastic baby bottles, and other popular kitchen items. Since some composite fillings contain plastic, many patients have concerns about exposure to BPA.

We will do our research and avoid using any composite filling that contains BPA (not all do), but even when the chemical is present, the amount released into the body is very small. If you have previous dental work and are concerned about the presence of BPA, we can discuss your options with you.
