Dental Bonding
Dental bonding is a painless, long-lasting, and simple outpatient procedure with no adverse risks for most people.

Dental or teeth bonding is a cosmetic procedure used to repair a chipped, cracked, or broken tooth. It helps close gaps or changes the shape (lengthening a tooth shorter than the rest) and color (discolored) of a tooth.

The bonding material is a tooth-colored resin material (a durable plastic material). It is applied and hardened with a special blue light, which helps restore the overall appearance of the teeth and enhances the smile.

What are the indications of teeth bonding?

Teeth bonding can do the following:

  • Repair decayed teeth
  • Fill cavities
  • Treat minor injuries
  • Repair chipped or cracked teeth
  • Improve the appearance of discolored teeth
  • Close spaces between the teeth
  • Make teeth look longer
  • Change the shape of teeth
  • Cosmetically replace amalgam fillings
  • Protect the tooth's root (exposed due to receding of gums)

How is dental bonding done?

Teeth bonding typically takes about 30 to 60 minutes per tooth to complete.


  • Little or no preparation is required for dental bonding.
  • The dentist chooses a composite resin color that closely matches the color of your tooth using a shade guide.


  • The surface of the tooth is roughened, and a conditioning liquid is applied so that the bonding material adheres to the tooth.
  • The tooth-colored, putty-like resin is applied, molded, and smoothened to give it the desired shape.
  • Then, the material is hardened using a bright light or laser, which bonds the material to the surface of your tooth.
  • After the material hardens, the dentist may trim, shape, and polish it to match the sheen of the rest of the tooth surface.


  • You can resume all normal activities immediately after the procedure.
  • Follow good and hygienic oral habits.
  • You might need touchups every 3 to 10 years.

How long does dental bonding last?

Though the lifespan of bonding materials for the teeth depends on certain factors, such as the extent of bonding and oral habits. However, bonding on the front teeth can last between 3 to 10 years.

It is a safe, painless, long-lasting, and simple outpatient procedure with no adverse risks for most people.
