Dental bonding is the use of a composite resin, usually a plastic, to fix broken, chipped or decayed teeth. It is a tooth-colored material that can be used to repair chipped and discolored teeth and help them to appear more attractive and longer. This cosmetic dental care procedure can also be used to close gaps between teeth or to reshape or make your teeth appealing. It can as well be used to protect a small portion of the root of a tooth that is visible due to gum receding.
