Bonding has many uses. The materials are very similar to those used in composite fillings, that is, “space age” plastics with tooth colored fillers to give them strength. The result is not only durable but wonderfully esthetic. These are but a few of the many uses for this versatile technique:
Once any decay or stain has been removed, the tooth is prepared for the procedure by lightly etching the surface and applying a bonding liquid. The bonding liquid is hardened with a high intensity light. A selection of shade matched composite resin materials are applied in layers, sculpted by the dentist and “cured” with the same light. Once set, the resin is trimmed, shaped, smoothed, and polished to a natural appearance.
The bonding procedure is normally completed in a single visit, and can significantly improve the appearance and strength of the treated teeth. Although quite durable, bonding resins are not as strong as natural tooth structure and are more likely to stain, chip or break, especially if abused. Bonded restorations typically last three to five years before repair or replacement is needed. Habits, such as night-time grinding (bruxism), nail-biting or a diet rich in high staining foods and beverages like tea and coffee, can alter their longevity.
