When only a portion of the tooth’s biting surface is damaged, it will often be restored wity an onlay.
What are dental onlays?
Onlays can be made of porcelain or gold. It is bonded to the damaged area of the tooth. An onlay is a substantial reconstruction, similar to a crown but conservative.
Traditionally, gold has been the material of choice for onlays. In recent years, however, porcelain has become increasingly popular due to its color, which can potentially match the natural color of your teeth.
How are onlays applied?
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 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 tooth and schedule the next appointment.
At the second appointment, the temporary is removed. Dr. Gardin will then make sure that the onlay fits correctly. If the fit is satisfactory, the onlay will be bonded to the tooth with a strong resin and polished to a smooth finish.
