Inlays & Onlays

Inlays and onlays are indirect dental restorations that reinforce an existing tooth that is too damaged to support a filling, but not damaged enough to require a crown. Inlays and onlays are known as indirect fillings because unlike a standard filling, both are made in a laboratory and cemented or bonded to the surface of the tooth during a second visit. Unlike standard fillings, inlays and onlays do not weaken the tooth structure, but actually strengthen it. The laboratory can make inlays and onlays from porcelain or gold.


Because both are fabricated in a dental laboratory, it usually takes two or more appointments to restore a tooth with an inlay or onlay.
