Inlays and Onlays
When more than half of the tooth’s biting surface is damaged, a dentist will often use an inlay or onlay.
What are dental inlays and onlays?
Our inlays and onlays are made with CEREC porcelain, all completed the same day. These pieces are adhesive cemented to the damaged area of the tooth. An inlay 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. However, CEREC technology offers porcelain that has the same strength and color as your natural teeth.
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 adhesively cemented 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 dental crown, onlays can provide a very good alternative, helping to preserve as much of what is naturally you, your tooth.
