Inlays/Onlays

Inlays and Onlays – What's the Difference?

Dentists frequently recommend inlays or onlays to restore damage to the chewing surfaces of posterior teeth. Inlays and onlays are typically used when large portions of the tooth are missing or corners need to be replaced. Dr. Rice, Dr. Hall, Dr. Rask use the Cerec^® machine for both inlays and onlays. They scan the prepared tooth which sends the image to the machine to be fabricated right here in the office! They'll fit your tooth precisely because the image measures every groove of the tooth. But what's the difference between the two?

Inlays fit within the grooves between the corners of your tooth. Onlays fit within the grooves and wrap up and over the corners, so they cover more of the tooth's surface. Dr. Rice and Dr. Hall will decide which is most appropriate for you, based on the amount of tooth structure lost to wear or decay. Inlays and onlays can be made of gold or porcelain and both have benefits in different situations.
