Bonding is a cosmetic procedure that can improve the appearance of teeth that are chipped, broken, cracked, stained, or gapped. With bonding, tooth-colored materials are attached, or bonded to a tooth surface. The process can improve unsightly stains from coffee, tea, tobacco or certain childhood medications; front-tooth gaps; and accident-induced cracks or chips. Bonding is also used to protect exposed tooth roots that resut from gum recession and to fill small cavities. Bonding usually lasts from three to five years.
The bonding process involves preparing the tooth surface with an etching solution that
allows the bonding material (composite resins) to adhere. Composite resins are plastic materials made of glass and resin. Various color resins are carefully blended to match the existing tooth and look completely natural. The resin is applied, contoured into the proper shape and hardened using a special light or chemical process. It is then smoothed and polished to appear natural. Bonding may not require the use of anesthesia or drilling and can usually be completed in one visit.
