Composite "white" fillings, made of composite, are used to restore teeth that have small cavities. They are called "white" fillings because of the natural, tooth color of the material. Unlike inlays and onlays that are crafted in an outside lab, composite fillings can be made on-site and completed in only one office visit.
A composite "white" filling is used when the cavity is small and the patient desires a natural-looking restoration. The dentist will numb the area, then prepare the tooth for restoration, removing any decay. He or she will then apply the composite, and fill the cavity. After the composite has been cured, it will be smoothed and shaped for fit and comfort.
