In previous years, this was the only way to fill a cavity. For the past few decades, however, tooth-colored composite fillings have become the primary option for treating tooth decay. Sure, they are much more natural-looking compared to metal fillings. But did you know there are plenty of other reasons to make this switch, as well? At Metropolitan Dental Care, we offer tooth-colored fillings as well as many other cosmetic and restorative treatments. Today, your general dentist in Lone Tree will discuss a few reasons to replace your old amalgam fillings with composite fillings.

Composite Does Not Expand or Contract with Temperature Changes

Amalgam fillings are derived from a metallic mixture of silver, tin, zinc, copper, and mercury. When temperature fluctuations occur, amalgam fillings expand and contract. Over time, this can gradually weaken the overall tooth structure, increasing the risk for damage or breakage.

Composite Fillings Bond with the Tooth Structure

When an amalgam filling is placed, it can be likened to filling a pothole. The mixture is simply packed into the void where the decay was removed. In contrast, a composite filling actually bonds to the tooth structure, increasing its strength and resiliency.

Composite Fillings are Less Likely to Leak

Because composite resin bonds to the tooth surface, tooth-colored fillings create a tight seal. This keeps bacteria and debris out and is more effective for protecting the tooth against recontamination.

Tooth-Colored Fillings Do Not Contain Mercury

Over the past several years, there has been quite the controversy surrounding the mercury in amalgam fillings. Despite statements from the American Dental Association claiming that dental amalgam is considered safe for use, some researchers insist that there is really no benign level of exposure. Approximately 50 percent of an amalgam filling is mercury. Some individuals claim that mercury vapor is absorbed by the body, which can lead to a number of health-related concerns. Mercury exposure has previously been linked to a host of problems, including neurological, kidney, urological, brain, and fertility issues, to name a few. While the jury is still out on the long-term effects of amalgam fillings, most patients find that peace of mind is reason enough to make the switch to composite restorations.

Composite Fillings are Aesthetically Pleasing

Of course, the most obvious advantage of composite fillings is that they blend in nicely with your surrounding teeth. Crafted from a mixture of quartz and glass, composite fillings can be color-matched to your adjacent teeth with great precision. Instead of noticeable metal specks in your smile, no one will be able to tell you’ve had dental work completed.
