Inlays and Onlays

When more than half of the tooth’s biting surface is damaged, a dentist will often use an inlay or onlay to repair it.

What Are Inlays & 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 & Onlays Applied?

Thanks to the advanced technology, inlays and onlays can be completed in just one appointment! The appointment begins with the previous filling being replaced or the damaged or decaying area of the tooth is removed, and the tooth is prepared for the inlay or onlay. A digital impression will then be created using the advanced E4D software. Our doctors will then fabricate a porcelain inlay or onlay to fit your tooth. Upon the confirmation of an excellent fit, 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 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.
