What Are Composite Fillings?

A composite uses two different types of material to take advantage of the best properties of each. Plastic lets composite fillings begin as a paste, then harden. It also gives them toughness. Embedded glass particles add strength to the filling.

Advantages of Tooth-Colored Dental Fillings

Composite fillings have many advantages:

  • Can be blended to match your natural tooth color
  • Bond directly to tooth, adding strength and creating a good seal
  • Can be placed in one appointment
  • Lower temperature sensitivity
  • Expand and contract at the same rate as tooth enamel—won’t cause temperature stress or cracking
  • Do not contain mercury or other heavy metals

The toxicity of metal amalgam fillings has not been established, but we know composite fillings to be safe.

Because of these limitations, we offer all our patients with the alternative of another tooth-colored filling option: porcelain inlays and onlays. These porcelain restorations are even more attractive than composite fillings because they not only match the color, they have the same luster as natural tooth enamel. In addition, porcelain inlays and onlays are the most durable restorations available.
