Inlays & Onlays

Repair Damaged Teeth with Inlays and Onlays

When more than half of the tooth’s biting surface is damaged a dentist will often use an inlay or onlay.

What are inlays and onlays?

Inlays and onlays can be made of porcelain, gold, or composite resin. These pieces are bonded to the damaged area of the tooth. An inlay, which is similar to a filling, is used inside the cusp tips of the tooth. An onlay is a more involved reconstruction, similar to the inlay but extending out over one or more cusps of the tooth.

Traditionally, gold has been the material of choice for inlays and onlays. In recent years, however, porcelain has become increasingly more and more popular due to its strength and color and ability to match the natural color of your teeth.

How are inlays and onlays applied?

Inlays and onlays require two appointments to complete the procedure. During the first visit, the filling that is being replaced, or the damaged or decaying area of the tooth is removed. The tooth is prepared for the inlay or onlay. To ensure a quality fit and correct bite, an impression of the tooth is made by the dentist, then sent to a lab for fabrication. The dentist will then apply a temporary restoration on the tooth and schedule the next appointment.

At the second appointment, the temporary is removed. Dr. Guess will then make sure that the inlay or onlay fits correctly. If the fit is satisfactory, the inlay or onlay will be bonded to the tooth with a strong resin and polished to a smooth finish.

Considerations for Inlays and Onlays

Traditional fillings can reduce the strength of a natural tooth by up to 50%. As an alternative, inlays and onlays, which are bonded to the tooth, actually increase the strength of a tooth by up to 75%. As a result, they can last from 10 to 30 years. In some situations, where the damage to a tooth is not extensive enough to merit an entire crown, onlays can provide a very good alternative.
