When more than half of a tooth’s biting surface is damaged, a dentist will often use inlays and onlays.
What is an Inlay/Onlay?
Inlays and onlays can be made of porcelain, gold, or a composite resin. These pieces are bonded to the damaged area of the tooth. An inlay, which is similar to a filling, is used inside the cusp tips of the tooth. An onlay is a more substantial reconstruction, but extends out over one or more of the cusps of the tooth.
Gold is in the Past
In the past, gold was the most used material for inlays and onlays, however in recent years, porcelain has become increasingly popular due to its strength and color which much closer matches the natural color of your teeth.
