Onlays fill teeth like inlays, but also cover the biting surface like a crown. They can be utilized to conservatively repair a damaged area of tooth due to trauma or decay while conserving healthy tooth structure.

Onlays can be made of porcelain or gold. Porcelain onlays are made to closely match your natural tooth color, so they look great and wear like natural teeth. However, the most durable option is a gold onlay.
