Porcelain Crowns, Inlays and Onlays - Naturally looking crowns, inlays and onlays are used to strengthen or repair cracked, broken or badly decayed teeth. We offer one-visit appointments for crowns, inlays and onlays using our high tech Cerec milling unit as well as a CAD-CAM machine that designs and mills restorations in minutes. Some patients require two visits to our office - one for designing the restoration and a follow up visit for permanent placement.
