Dental bonding is a conservative cosmetic treatment that improves the appearance of chipped, discolored, or misshapen teeth using composite resin to repair and restore the tooth surface.

Bonding can transform the appearance of a smile. The procedure is commonly used for:

  • Repairing chips and minor cracks
  • Covering stained or discolored enamel
  • Closing small gaps between teeth
  • Remodeling the contours of teeth which are undersized, crooked, or misshapen
  • Rebuilding areas where enamel erosion has taken place
  • Creating inconspicuous, tooth-colored fillings

The procedure begins with an exam to make sure the tooth is healthy and a good candidate for bonding. The tooth surface is prepared, and a specially formulated dental adhesive is applied which enables the composite resin to “bond” to the tooth structure.

The composite resin is put in place and molded to the desired shape. The resin is color-matched to your teeth so it blends in with the enamel around it. Once in place, the resin is hardened with a curing light. The bonding is given a final check for fit and shape, then smoothed and polished.

Bonding is a popular choice in cosmetic dentistry because it is convenient, cost-effective, and minimally invasive.

  • Bonding can frequently be completed in one visit, and often without the use of anesthetic.
  • Bonding is less expensive than veneers or crowns.
  • While veneers and crowns last longer and are less vulnerable to chipping or staining, these procedures require the removal of more tooth structure.

Dental bonding isn’t right for every tooth. Large chips and cracks, deep decay or serious misalignment may need a different treatment, so talk with your dentist about whether bonding fits your case.

Dental Bonding FAQs

How long does dental bonding last?

Bonding usually lasts several years before it needs touching up or replacing. It lasts longer if you avoid biting nails, pens and ice, and wear a night guard if you grind your teeth.

Does dental bonding hurt?

Usually not. Most bonding is done on the surface of the tooth without numbing. If we’re filling a cavity at the same time, we numb the area first.

Bonding or veneers: which should I choose?

Bonding costs less, takes one visit and removes little or no enamel, but it can chip and stain over time. Porcelain veneers last longer and resist stains, but cost more and take more than one visit. Our post on the pros and cons of veneers compares them in more detail.

Can bonded teeth be whitened?

No. Whitening gel doesn’t change the color of bonding material. If you want whiter teeth, whiten first and then match the bonding to your new shade.

How much does dental bonding cost?

It depends on how many teeth and how much material each one needs. We’ll give you the cost at your visit. Insurance sometimes covers bonding that repairs a chip or a cavity, but not purely cosmetic bonding.
