Dental Inlays and Onlays
When more than half of the tooth’s biting surface is damaged a dentist will often use an inlay or onlay.
Call Bergen County Dentists at Edward Feins, DMD PA, River Vale Phone Number 201-666-3300 if you have any questions about Dental Inlays & Onlays or to schedule your appointment.
What are Dental 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.
How are Dental Inlays & Onlays Applied?
Dental inlays and onlays only require one appointment to complete the procedure. During the 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, a digital impression of the tooth is taken by the dentist. Using our CEREC® system, a virtual design of your tooth is created and sent to our milling unit. Within minutes, your restoration will be made.
Dr. Feins and Dr. Shao 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.
Considerations for Inlays/Onlays
Traditional fillings can reduce the strength of a natural tooth by up to 50%. As an alternative, dental inlays and onlays, which are 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 dental crown, onlays can provide a very good alternative.
