Crowns, Inlays, & Onlays
When additional support is needed for natural tooth structure, a crown, inlay or onlay might be required. A variety of materials are available for these restorations including porcelain, porcelain fused to metal, or metal. These restorations restore the structural integrity to the damaged tooth. The term “crown” is synonymous with the term “cap” and covers the tooth structure visible above the gum line. An inlay and onlay fit into the tooth much like a large filling, but in one solid piece. All of these restorations are created in a dental laboratory; therefore, two appointments are required to complete the procedure.
The first visit involves preparing the natural tooth, taking an impression for the laboratory, and then placing a temporary over the remaining tooth structure for support. The permanent crown is adjusted and cemented at the second visit.
