A composite filling is a white resin filling that is used as an alternative to amalgams and veneers. This is an excellent cosmetic option for those patients who do not want the look of silver in their mouths and do not want the expense of veneers. Composites can be used on teeth that are decayed, cracked, or stained.
The procedure is usually completed in one visit. The first step is to remove the decayed or unsightly portion of the tooth. The tooth is then etched with a gel and a bonding agent is then applied. This will allow the composite resin to be bonded in place in the prepared tooth. The resin is then trimmed and polished, leaving you with a beautifully sculpted, natural-looking restoration.
Although composites are esthetically pleasing and easily placed, they generally don't last as long as other types of restorations. These resins typically last from 5-7 years before they begin to stain and wear away. When this happens, the restoration will need to be replaced.
