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 substantial restoration, similar to the inlay but extending out over one or more of the cusps of the tooth.

Traditional fillings can reduce the strength of a natural tooth by up to 50%.

Traditionally, gold has been the material of choice for inlays and 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 they 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 taken, and sent to a lab for fabrication. Dr. Grayson will then apply a temporary restoration on the tooth and schedule the next appointment.

At the second appointment, the temporary restoration is removed. Dr. Grayson 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 cement and polished to a smooth finish.

Considerations

Most dental restorations have a life expectancy of approximately 10 years. Many patients wear restorations much longer with no damage to their restorations. It is important to maintain regular dental visits and practice good oral hygiene to help insure the longevity of dental restorations.
