Composite bonding offers the possibility of completely changing your smile without any tooth preparation at all. We bond filling material that is colour matched to your teeth and shape it to give you a new smile. The filling material is very robust, but not as strong as veneers and can chip.However, it is a simple matter to repair. Also, the material stains particularly if you smoke. Composite bonding is significantly cheaper than veneering but requires far more maintenance. It lasts for about 4 years.
