In the incidence of a tooth that is broken or damaged, the process of an onlay could be an option for your tooth. The onlay will encompass a broken or decayed tooth to provide protection and increased strength. The onlay process will require less tooth removal than a crown.
In the incidence of a broken tooth, inlays and onlays are a form of indirect restoration. An inlay will incorporate the pits and fissures of a tooth, mainly encompassing the chewing surface between the cusps, whereas, an onlay will involve one or more cusps being covered. Inlays and onlays are used in molars or premolars, when the tooth has experienced too much damage to support a basic filling, but not so much damage that a crown is necessary. If all cusps and the entire surface of the tooth is covered this is then known as a crown.
