Dental inlays repair the chewing surface of your tooth. Our office may use dental inlays to repair teeth that have other restoration options such as a large dental filling. You can have your inlays created of tooth-colored porcelain or composite resin. Most inlays are more durable than composite or amalgam fillings. They are also less expensive than a dental crown. Your onlays may be made from various materials including porcelain, gold, and resin. The difference between these three materials is their appearance. It generally takes two visits to complete an onlay.
