Dental Inlays and Onlays
Dental inlays and onlays repair a tooth when more than half of the tooth's biting surface is damaged. They serve as an alternative to traditional fillings and can strengthen the tooth by up to 75 percent, whereas traditional fillings can weaken the tooth by up to 50 percent.
Dental Inlays and Onlays near Palos Heights, IL
Dental inlays and onlays are durable restorations used to repair and strengthen damaged teeth without the need for a full crown. Bonded with high-strength resin, they can increase tooth strength by up to 75% and often last 10 to 30 years.
Made from porcelain, gold, or composite resin, inlays fit within the cusps of a tooth, similar to a filling, while onlays cover one or more cusps for more extensive repair. Although gold has long been used, porcelain is now a popular choice because of its strength and natural, tooth-colored appearance.

What are inlays and onlays?
Inlays and onlays are made from porcelain, gold, or composite resin and are bonded directly to the damaged portion of the tooth. An inlay fits within the cusps, similar to a filling, while an onlay covers one or more cusps for more extensive restoration.
While gold has traditionally been used, porcelain has become a popular option thanks to its strength and natural, tooth-colored appearance.

How are dental inlays and onlays applied?
Dental inlays and onlays are typically completed in two visits. At the first appointment, the damaged or decayed portion of the tooth is removed and the tooth is prepared. An impression is taken to ensure a precise fit and proper bite, then sent to a dental lab for fabrication. A temporary sealant is placed, and your next visit is scheduled.
At the second appointment, the temporary sealant is removed and the inlay or onlay is carefully checked for fit and comfort. Once approved, it is bonded to the tooth with a strong resin and polished for a smooth, natural finish.

When should I consider a dental inlay or onlay?
A dental inlay is used to repair damage or decay within the grooves of a tooth and restore areas that affect the cusp. Inlays are more durable than traditional composite or amalgam fillings, with gold inlays offering the greatest longevity.
A dental onlay is recommended when damage is more extensive and involves the cusp tips or biting surface of the tooth. Because onlays are custom made, a temporary restoration is placed while the final onlay is fabricated by a dental lab.
