Inlays & 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 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 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.

Onlays/Inlays are used when a cavity is too big for a filling but not big enough for a crown. An inlay is a filling that is within the cusps, whereas an onlay “overlays” the cusp providing strength and protection to the tooth. Inlays and onlays may be 18 karat gold or tooth-colored. Inlays and onlays can now be provided in a single visit with Dr. Funke by using CEREC technology.

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 schedule the next appointment.

At the second appointment, the temporary sealant is removed. Dr. Funke 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.
