Dental inlays are used to repair cavity damage, onlays can be used to repair a broken cusp, and crowns restore the shape and strength of a tooth. These long-lasting restorations will help to preserve your smile.
An inlay would be recommended for a deep cavity. An onlay may be used for more extensive damage that spreads to the cusp. And a crown would be suitable for restoring the shape, size or strength of a tooth, particularly after root canal therapy. Porcelain or composite material may be used to create the custom restoration that restores the form and function of the tooth.
Your restoration will be completed over two visits. During the first visit, your dentist will prepare the tooth and take impressions using a digital scanner. This helps to create a restoration that is an ideal fit for your mouth. During the second visit, your dentist will permanently fix the inlay, onlay or crown in place.
This depends on the placement and other lifestyle factors such as teeth grinding and diet. As with all dental restorations, they require good oral hygiene to help maintain them. A dental inlay or onlay may last for 15-20 years, which is considerably longer than most fillings. A dental inlay, onlay or crown is considered to be a long-term restoration.
