A "bonding", "resin filling", or "white filling" is a composite resin 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. Bondings can be used on teeth that are decayed, cracked, or stained.
The bonding 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 liquid or gel and a bonding agent is then applied. This will allow the composite resin to be placed in the prepared tooth. The resin is then trimmed and polished, leaving you with a beautifully sculpted, natural-looking restoration.
Although composite resins are cosmetically pleasing and easily placed, their durability is not as strong as other types of restorations. These resins typically last from 4-7 years before they begin to chip and wear away. When this happens, the restoration will need to be replaced.
