When over 1/2 of the tooths biting surface is damaged a dentist will often use an inlay or onlay. 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.
Inlays and onlays can be made of porcelain, gold, or composite resin. Traditionally, gold has been the material of choice. 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.
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. Klein or Dr. Rubinstein will then apply a temporary sealant on the tooth and schedule the next appointment.
At the second appointment, the temporary sealant is removed. Dr. Klein or Dr. Rubinstein 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.
Traditional fillings can reduce the strength of a natural tooth by up to 50%. As an alternative, inlays and onlays, being bonded directly onto the tooth using special high-strength resins, can actually increase the strength of a tooth by up to 75%. As a result, they can last from 10 to 30 years. In some cases, where the damage to the tooth is not extensive enough to merit an entire crown, onlays can provide a very good alternative.
