Inlays & Onlays
When more than half of the tooth’s biting surface is damaged, a dentist will often use an inlay or onlay.
What are 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 inlays and onlays applied?
Inlays and onlays require just one visit. Our doctors will prepare your tooth to preserve as much structure as possible. The doctor then takes a 3-D scan of the tooth and surrounding structures and designs the restoration digitally with the CEREC CAD-CAM. Your beautiful inlay or onlay will be milled in house and cemented on the same day!
Considerations for inlays and onlays
Traditional fillings can reduce the strength of a natural tooth by up to 50 percent. As an alternative, 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 percent. 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.
