Bonding and Composite Resins
Bonding of composite resins is ideal for smaller corrections, in which most of the tooth is healthy and stable. It can be used to correct a wide variety of problems, including minor decay, chips, cracks, gaps between teeth, discoloration and crooked teeth. Composite resins are a more esthetically-pleasing alternative to metal fillings or restorations.
Composite resins are materials that have similar characteristics to a tooth’s natural enamel, and their color can be adjusted to match the particular color of your teeth.
Bonding is a non-invasive procedure that can provide astounding improvements in the appearance of your teeth.
Unlike some veneers, composite resins do not protect against future discolorations. As with your natural teeth, regular cleanings are important. On average, composite resin restorations last between 7 and 11 years.
Dental bonding procedures can usually be completed in one or two office visits. For minor alterations, the resin can be matched to your teeth while you are in the office. For more extensive alterations, an impression of the area needs to be taken and sent to a lab, where the final restoration will be constructed. Larger, custom-designed restorations are usually composed of porcelain, rather than composite resin. Your custom restoration is bonded to the teeth on a second visit.
During the bonding procedure, a mild etching solution is first applied to the area of natural tooth enamel to receive the restoration. This solution roughens the surface which allows for a stronger bond between the tooth and resin.
Next, the resin is placed on the tooth and treated with ultraviolet light that activates bonding. Your dentist then sculpts the resin to the desired shape, and finally polishes the area. Several coats of resin may be applied.
