Dental Inlays & Onlays

When more than half of the tooth’s biting surface is damaged a dentist will often use inlays/onlays.

What are inlays/onlays?

Inlays and onlays can be made of porcelain, gold, or a 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 substantial reconstruction (similar to the inlay), but extending out over one or more of the cusps of the tooth.

Traditionally, gold has been the material of choice for inlays/onlays. In recent years, however, porcelain has become increasingly popular due to its strength and color which can potentially 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 being replaced or the damaged or decaying area of the tooth is removed and the tooth is prepared for the inlay or onlay. To ensure proper fit and bite, an impression of the tooth is made by the dentist and sent to a lab for fabrication. The dentist will then apply a temporary sealant on the tooth and a subsequent appointment will be scheduled.

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

Considerations for Inlays and Onlays

Traditional fillings are the ideal treatment option for small cavities.  When the tooth has a large amount of decay or damage, there are better restorative choices for improved strength and longevity..  When the damage to the tooth is not extensive enough to merit an entire dental crown, inlays and onlays can provide a very good alternative.
