Inlays and Onlays

What Is an Inlay?

An inlay is a lab made filling that is fitted into the grooves of a tooth and do not extend over the cusps of the tooth. The dentist removes the decay from the tooth and takes an impression, which is sent to a lab to make the inlay. This is then cemented into the tooth as a permanent restoration to repair the chewing surface. Dental inlays are generally more durable than regular fillings.

Inlays are manufactured from different materials but mainly porcelain or composite resin material matching the colour of the tooth. Gold inlays are the most durable but the most expensive of the materials available.

What Is an Onlay?

An onlay is in between an inlay and a crown. It is used to repair a tooth that has more extensive damage affecting the cusp or tips of the tooth. It is prepared in the same way as an inlay by sending an impression to a lab to have the onlay custom made.
