Your cosmetic dentist will help you decide if inlays and onlays are the best procedure for you. They restore areas of a tooth that are damaged by decay or trauma. Inlays and onlays are crafted in the dental lab from hard ceramic material and permanently cemented to the tooth. 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 providing you with a beautiful smile.
