Inlays and Onlays


Porcelain Inlay and Onlay

Inlays and onlays are a restorative solution for larger cavities or a tooth with more decay in one area.


The difference between an inlay and an onlay is the area of the tooth anatomy being restored. Inlays are used for cavities in the grooves, pits, or fissures of the tooth’s biting surface while onlays are used for decay in the tooth cusps. Both inlays and onlays are used to restore areas where tooth decay is present and the tooth structure has been compromised.

Inlays and onlays can be made with either cast gold alloy or with tooth-colored ceramic or porcelain materials. A model of the natural too is made prior to any procedure so that the restoration can be made to replicate the shape and function of the natural tooth. Prior to being cemented or bonded in place, the shape and fit of the restoration is verified. Inlays and onlays are extremely durable and make a great restorative solution in many cases.
