Inlays & Onlays
When more than half of a tooth’s biting surface is damaged, we can use an inlay or onlay to restore the tooth’s anatomy.
What are dental inlays and onlays?
Inlays and onlays are made of porcelain, gold, or composite resin and are bonded to the damaged area of the tooth. An inlay, which is similar to a dental filling, is placed inside the cusp tips of the tooth.
Porcelain is a great option due to its strength and color, which has the potential of matching the natural color of your teeth.
How are inlays and onlays applied?
Two appointments are required for the completion of inlays and onlays.
First Appointment
During the first visit, the damaged or decaying area of the tooth (or the filling that is being replaced) is removed, and the tooth is prepared for the inlay or onlay. To ensure proper fit and bite, we make an impression of the tooth and send it to a lab for fabrication. Dr. Dar, Dr. Heffelfinger, Dr. Abbass, Dr. Patel, Dr. Chaudhry, Dr. Castillo, Dr. Pan, Dr. Murad, and Dr. Stimpson then applies a temporary sealant on the tooth and schedules the next appointment.
Second Appointment
At the second appointment, the temporary sealant is removed. Next, your doctor will make sure that the inlay or onlay fits correctly. Once satisfactory, the inlay or onlay is bonded to the tooth with a strong resin and polished to a smooth finish.
Considerations for Inlays and Onlays
Traditional fillings can reduce the strength of a natural tooth by up to 50 percent. Alternatively, inlays and onlays, which are bonded directly onto the tooth, actually increase the strength of a tooth by up to 75 percent. As a result, they can last from for many years. In some cases, where the damage to the tooth is not extensive enough for a dental crown, onlays provide a very good alternative.
