Bonding is tooth-colored material used to fill in gaps or change the color of teeth. Requiring a single office visit, bonding lasts several years. Bonding is more susceptible to staining or chipping than other forms of restoration. When teeth are chipped or slightly decayed, bonded composite resins may be the material of choice. Bonding also is used as a tooth-colored filling for small cavities. Additionally, it can be used to close spaces between teeth or cover the entire outside surface of a tooth to change its color and shape.
Considerations for Dental Bonding?
- To repair decayed teeth (composite resins are used to fill cavities)
- To repair chipped or cracked teeth
- To improve the appearance of discolored teeth
- To close spaces between teeth
- To make teeth look longer
- To change the shape of teeth
- As a cosmetic alternative to amalgam fillings
- To protect a portion of the tooth's root that has been exposed when gums recede
Procedure for Having a Tooth Bonded?
- Preparation. Little advance preparation is needed for dental bonding. Anesthesia is often not necessary unless the bonding is being used to fill a decayed tooth. Your dentist will use a shade guide to select a composite resin color that will closely match the color of your tooth.
- The bonding process. Next, the surface of the tooth will be roughened and a conditioning liquid applied. These procedures help the bonding material adhere to the tooth. The tooth-colored, putty-like resin is then applied, molded, and smoothed to the desired shape. An ultraviolet light or laser is then used to harden the material. After the material is hardened, your dentist will further trim and shape it, and polish it to match the sheen of the rest of the tooth surface.
- Time-to-completion. Dental bonding takes about 30 to 60 minutes per tooth to complete.
