Dental bonding is a procedure in which a tooth-colored resin material (plastic material) is applied on your teeth and hardened with a special light, which ultimately "bonds" the material to the tooth to restore or improve a person's smile.

Bonding is a popular treatment option because it provides a successful attachment between the filling material and the tooth’s original enamel and dentin. It looks like the original tooth and functions like it as well.

Direct composite bonding is used to recreate a smile in an additive manner, where little or no tooth reduction is needed. Direct bonding, in the hands of a skilled dentist, is less costly than porcelain veneers and crowns and can be long-lasting with proper maintenance.

Why do we need dental bonding?

Dental bonding can:

  • Repair decayed teeth (composite resins are used to fill cavities)
  • Repair chipped or cracked teeth
  • Improve the appearance of discolored teeth
  • Close gaps between teeth
  • Make teeth look longer
  • Change the shape of teeth
  • Be used as a cosmetic alternative to amalgam fillings
  • Protect a portion of the tooth's root that has been exposed due to receding gums

What is the procedure?


Little preparation is needed for dental bonding. Anaesthesia is often not necessary unless the bonding is being used to fill a decayed tooth. Your dentist will use a shade guide to select a composite resin colour that will closely match the colour of your tooth.


Next, the surface of the tooth will be roughened and a conditioning liquid applied. These procedures help the bonding material adhere to the tooth. The tooth-coloured resin is then applied and smoothed to the desired shape. An ultraviolet light or laser is then used to harden the material. After the material is hardened, your dentist will further shape it, and polish it to match the rest of the tooth surface.

What about aftercare?

With normal care, today's composite material is durable enough to last without regular attention. You won't need to seek out your dentist for special visits.

Because bonding material can chip, it is important to avoid such habits as biting fingernails, chewing on pens, ice, or other hard food objects, or using your bonded teeth as openers.

What is the longevity of dental bonding?

The longevity of the results depends on how much bonding was used and your personal oral hygiene habits. Typically, however, bonding materials last from three years up to about ten years before needing to be replaced.

A consultation with your dentist will determine if you are a candidate for this particular treatment. Your dentist will examine you in detail, that may involve x-rays and an evaluation of your teeth and gums.

If you have teeth that are extensively damaged your dentist may recommend other restorative or cosmetic procedures that are more appropriate for your specific needs.
