Bonding is a quick, painless in-office procedure to repair cracks, chips, gaps between teeth or cover stained teeth to enhance your smile. Bonding can often be done without anesthesia if there is no decay or pulp exposure. The bonding material is developed in many shades allowing the dentist to accurately match the shade of your natural teeth. The composite resin forms a durable, stain resistant surface that is later smoothed and polished to give it a natural appearance and feel.
