What is Bonding?

What is bonding?

Bonding is the application of applying tooth colored composite resin filling that is placed on the teeth.  Bonding is used to repair decayed, chipped, fractured, and discolored teeth.  It is primarily used for cosmetic purposes, such as improving the appearance of a chipped tooth, closing spaces between teeth, making teeth look longer, and changing the shape or color of teeth.

How is bonding applied? 

Your dentist will use a shade guide to select the composite resin color that will match the color of the tooth most closely.

Once your dentist has chosen the color, he or she will slightly abrade or etch the surface of the tooth to roughen it. The tooth will be coated lightly with a conditioning liquid, which helps the bonding material adhere.

When the tooth is prepared, your dentist will apply the tooth-colored, putty-like resin. The resin is molded and smoothed until it’s the proper shape. Then the material is hardened with an ultraviolet light or laser.

After the bonding material hardens, your dentist will further trim and shape it. Then he or she will polish the material until it matches the sheen of the rest of the tooth surface.

It usually takes about 30 minutes to an hour to complete the procedure.


The composite resin used in bonding isn’t nearly as strong as a natural tooth. Biting your fingernails or chewing on ice or pens can chip the material. Bonding usually lasts several years before it needs to be repaired. How long it actually lasts depends on how much bonding was done and your oral habits.
