Inlays and Onlays

What are inlays and onlays?

Dental inlays and onlays are used when old fillings need to be removed or replaced. A dental inlay is similar to a filling and fits inside the top edges of the tooth. A dental onlay is more extensive and extends over the cusps of the tooth. Inlays and onlays offer a conservative preparation that preserves and protects as much of the healthy tooth as possible.


What are inlays and onlays made from?

Inlays and onlays are made from porcelain, gold or resin materials. They are an abbreviated form of a crown.


How long does the entire treatment process take?

Generally there are two appointments for inlays and onlays. The first is the preparation of the filling and an impression is taken, the second appointment the permanent custom-made inlay/onlay is cemented in place.


How long do they last?

Inlays and Onlays usually last as long as a crown, but the advantage is more tooth is maintained.


What are the risks involved?

Occasionally, the preparation can implicate the nerve of the tooth. This might happen if the tooth has a very large filling or a crack in the tooth; with careful planning and prior radiographic assessment this is minimised.
