Inlays and Onlays
When over half of a tooth’s biting surface is compromised by decay or wear, a dentist will often choose to restore the tooth with an inlay or onlay.
Inlays and onlays can be made of porcelain, gold, or composite resin. These restorations are bonded to the damaged area of the tooth. An inlay, which is similar to a filling, is placed within the cusp tips of the tooth; an onlay is a more substantial reconstruction, similar to the inlay but extending out over one or more of the cusps of the tooth.
Traditionally, gold has been the material of choice for inlays and onlays. In recent years, however, porcelain has become increasingly popular due to its strength and color, which can ideally match the natural color of your teeth.
