Inlays and onlays are a type of indirect restoration, where your dentist fabricates the restoration outside of your mouth and cements it into place.
Inlays and onlays are used in molars or premolars, when the tooth has experienced too much damage to support a basic filling, but not so much damage that a crown is necessary. Inlays and Onlays are porcelain puzzle-piece like fillings, milled in the office and are applied by Dr. Kania, in the same day visit. An inlay is used when the cavity rests between the cusps, whereas an onlay covers one or more cusps, as well as the area in between. A crown replaces the entire outside area of the tooth above the gum line.
