Bonding

Dental bonding

Bonding is a treatment that can be used to repair teeth that are decayed, chipped, fractured or discoloured or to reduce gaps between teeth.

For this procedure, a dentist mixes composite resin — a type of plastic — into a paste, then tints the mixture to whiten or match the color of your teeth. Several layers of resin are applied to each tooth. Each layer is hardened under an ultraviolet light or laser. Final steps include shaping and polishing the resin material so the finished tooth looks natural and smooth.

Bonding can also be used to build up older teeth to make them appear younger. Bonding is an option for people of all ages, including children, as the resin can be replaced as teeth grow.

Veneers

Veneers are strong, thin pieces of porcelain that are bonded to the teeth. They are used to repair chipped, decayed or stained teeth and may help in closing gaps between teeth.

With a bit of contouring, veneers may also correct slightly crowded or overlapping teeth. If your teeth have discoloured with age, a veneer may improve their appearance.
Veneers can also be used for cosmetic reasons instead of crowns, which are more often used for badly damaged or decayed teeth. The tooth enamel needs to be ground down slightly in order to accommodate the veneer.

Veneer preparations frequently require the use of local anesthetic and, depending on colour and shade, may take more than one appointment to complete.
