Composite bonding can improve the appearance of teeth by either repairing or concealing concerns, such as chipped, cracked, worn or discoloured teeth. This strong, tooth-coloured resin is applied to the affected area and carefully shaped to look like your natural tooth. A special light is then used to harden this material, making it a permanent part of your tooth. Bonding is a more conservative alternative to restorations like porcelain veneers, which often require some degree of tooth preparation.
