Bonding

  • WHAT IS BONDING?

    Bonding, or bonded restoration, is a painless way to make minor tooth repairs. In most cases, several teeth can be bonded in one dental visit. This process uses tooth-coloured material, called composite resin. Composite resin is put on the tooth, then shaped and hardened with light. This resin can be:

    • Used to build up teeth and fill between them
    • Used on a broken tooth to restore it to size
    • Matched to your teeth
    • Shaped to look like the missing part of a chipped tooth
    • Painted over a stained tooth to make it match the colour of your other teeth

    HOW BONDING IS DONE?

    Your dentist places a matrix between the tooth being treated and its neighbouring teeth. A matrix is a thin, clear plastic film that protects other teeth from stray resin.

    A mild chemical is then applied to the tooth to help the resin bond to the enamel. Your dentist puts the carefully colour-matched resin on your tooth in layers. A light is then used to harden each layer  and after the last layer is hardened, your dentist shapes and polishes it to form your tooth. The finished tooth looks natural and smooth. At your next dental visit, your dentist will examine the bonding and polish it if needed. Over time, the bonding may wear down and your dentist may touch up the bonding with more composite resin.
