Repairing your teeth
A composite filling is a tooth-colored plastic and glass mixture used to restore decayed teeth. Composites are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.
As you might imagine, patients often choose composite resin for aesthetic purposes. But dentists have other reasons to promote composite resin as a dental filling material. While amalgam fillings require a larger section of the tooth to be removed, dentists only need to drill away the diseased part of the tooth to place composite resin. This preserves the existing tooth structure for years to come.
Crowns become necessary when there is insufficient tooth structure to support a filling. Teeth that are severely broken down from decay or fracture can be fully restored to proper appearance and function with a crown restoration.
Sometimes referred to as a cap, a crown is made from either ceramic or gold (or a combination of both) and shaped to mimic a natural tooth. It is actually fitted over the remaining part of your own tooth which means less removal of your original teeth, and a stronger, more natural looking result.
