Times Where An Onlay Is Your Best Option


You may have heard of an onlay, used in connection with bonding, although it can be made of a number of various materials. This type of dental restoration is often recommended to fill a large cavity. While we often fill cavities with a traditional filling material, we may determine that an onlay will offer more retention and strength. Again, this type of restoration is used to fill a larger area of decay and therefore is advised when a filling will not work.


How Is An Onlay Different Than An Inlay?

You can use an onlay or inlay to fill a large decayed area of the tooth. However, the two provide different coverages. For example, an onlay covers the cusp of a tooth while an inlay is made to fill the space between the cusps. An onlay restoration can last a long time – from 10 to 15 years. This type of filling is suggested as an option to a dental crown. Only a small portion of the tooth is cut away, which ultimately strengthens the tooth.


When Is An Only Recommended And What Does The Procedure Involve?

We frequently suggest an onlay when a tooth has deteriorated to a noticeable degree, or the tooth has had a root filling. The tooth may also have a large filling that no longer supports the tooth adequately. Therefore, an onlay replacement is made to prevent further breakdown of the tooth. If teeth contain stained tooth-colored fillings, we may suggest they be replaced with onlays. The onlay can be made of porcelain, ceramic, or a composite resin material. If you get an onlay in a day, ceramic CEREC and CAD CAM technology is used so the tooth impression and fabrication of the onlay can be done onsite.
