Inlays and Onlays

Inlays and Onlays

These two types of restorations are used when there is decay present on the natural tooth surface. The main difference between an inlay and onlay is whether or not the “filling” covers or re-creates the tooth’s cusps (tooth’s protrusions). Unlike the traditional “filling” that is done by the dentist right in his / her office, inlays and onlays are designed and crafted in a dental lab. Historically, inlays and onlays were made of gold. Today, there are ceramic materials available that are just as durable as gold and yet are aesthetically more pleasing. The two main advantages of inlays and onlays are durability and better protection against recurring decay.
