Like fillings, inlays and onlays restore areas of a tooth that are damaged by decay or trauma. While fillings are composed of a soft resin or plastic composite that is molded into place and then hardened during the dental visit, inlays and onlays are crafted in the dental lab from hard ceramic material and permanently cemented to the tooth during a follow-up visit. Inlays fill cavities in the middle of the tooth surface, and onlays restore a damaged cusp to provide added support. These premium dental restorations can last for many years with proper care.
