Bonding/White Fillings
A bonding is a tooth colored composite resin that is used as an alternative to amalgams(silver fillings) and porcelain veneers. Ther are many reasons why this material is the best choice for most restorations. Composite is a metal free material that has many of the same characteistics of natural tooth. It bonds to a tooth both chemically and mechanically, which allows the dentist to conservatively remove small areas of decay. Amalgam fillings rely on mechanical retention alone, and more tooth structure than necessary must often be removed to meet the depth requirements. Composite fillings are an excellent cosmetic option for those patients who do not want the look of silver in their mouths. Bondings can be used on teeth that are decayed, cracked, or stained.
Procedure
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.
Bonding Durability
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. On posterior teeth, with larger decayed or broken areas, the option to onlay a tooth may be the better long-term restoration. Allen Valley Dental works with its patients to inform and educate about the best materials and choices on an individual basis.
