When more than half of the tooth’s biting surface is damaged or an entire cusp has broken off, Dr. Dina will often recommend an onlay to restore the tooth. Onlays are lab-fabricated restorations that precisely fit your tooth, and can be thought of as an intermediate between an in-office restoration and a crown. They can be made of composite, porcelain, or gold, and are bonded to the tooth. 

How Are Onlays Completed?

Onlays require two appointments to complete. During the first visit, the filling being replaced or the damaged or decayed area of the tooth is removed, and the tooth is prepared for the onlay. To ensure proper fit and bite, an impression of the tooth is made and sent to our lab for fabrication, and a temporary restoration is placed. 

At the second appointment, the temporary is removed and the onlay is placed to verify proper fit. It is then bonded to the tooth with a high-strength resin and polished to a smooth finish.
