When a tooth has suffered damage or decay but does not need a full crown, our dentist may suggest inlays or onlays. Also known as indirect fillings, these restorations are strong and long lasting. Unlike traditional fillings that are placed during the dental visit, indirect fillings are created in a dental lab first and then securely bonded to the affected tooth at a later dental visit.

Inlays

When the center of the tooth is decayed or damaged, it may require an inlay. The first dental visit will include a dental impression, which will then be sent to a lab. The lab will create the permanent inlay, which will be placed and permanently bonded to the tooth at the second dental visit. Inlays tend to create a tight seal with the natural tooth, reducing the risk of future decay. They have a long lifespan and can last as long as 30 years, in some cases.

Onlays

When the biting surface or cusps of the teeth are damaged or decayed, they may require onlays. An onlay is designed to provide full coverage of the biting surface. They generally require two visits to place. At the first visit, our restorative dentist will take careful impressions and may add a temporary filling to protect the damaged or decayed tooth. The lab will then make the onlay to fit the impression and your mouth perfectly. At the second visit, our local dentist will bond the onlay to the tooth, where it can strengthen and seal the tooth against further damage.

Indirect fillings are usually made of porcelain or resin materials, and there are many benefits associated with their use. They closely match natural tooth colors and do not contain mercury or any other known hazards. They do not expand and contract the way metal fillings can, which reduces the risk of cracking or damaging the original tooth. Additionally, because they are custom made to fit each tooth, they are easy to clean and may better fit into tight areas.
