Bonding is an alternative to veneers, and can be used as a restorative procedure for teeth that are chipped, cracked, discolored or misarranged. In some instances, bonding can be used to close spaces or gaps between teeth.
How does it work?
Bonding may or may not require any preparation of the tooth. After tooth preparation, if it is needed, the surface of the tooth is etched and a bonding liquid is applied. Once the liquid sets, a tooth colored, plastic resin is applied and sculpted into the desired shape by the dentist. Once set, the resin is trimmed, smoothed and polished to a natural appearance.
The bonding procedure can be completed in a single office visit, and can improve the appearance of a tooth significantly. However, since the plastic resin used is not as strong as your natural tooth enamel, it is more likely to stain, chip or break than natural teeth. Bonding typically lasts three to five years before need of repair. Bonding is not reccommended in patients who grind their teeth or who have certain types of bites.
