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. If you feel that you could benefit from replacing old natural-tooth colored fillings with an onlay restoration, we can answer your questions about the process we follow. This type of dental restoration is easy to get and is a conservative alternative to a crown. If you want a durable tooth-colored restoration that will support a natural-looking smile, you will find that an onlay may be a viable solution for you.
