Inlays & Onlays
An inlay or onlay rather than a filling is used when more than 1/2 of the biting surface of molar has decayed, broken or been undermined. An inlay is placed within the bumps (cusps), whereas an onlay covers (replaces and strengthens the tooth) on or more bumps (cusps) and is more comprehensive. Onlays and inlays typically require 1-2 visits to complete. These restorations can be made of composite resin, ceramics or gold. Dependent upon the material used, the location of the placement and the forces encountered, inlays and onlay restoration can last at least seven years, and often much longer.
