The inlay is a filling, made by a dental technician, which restores the tooth anatomically. As well as inlays, there are also onlays and overlays. The type used depends on which surface of the tooth has to be replaced.
When is it needed?
When the tooth decay is so advanced that the remaining tooth material cannot be restored using a simple filling.
In such cases the dentist fits an inlay, which the dental technician makes, and which corresponds to the shape of the tooth, based on the impression taken in the surgery.
