What is a inlay and onlay?
You can sometimes have inlays or onlays instead of filling to repair damaged teeth. Fillings are soft to begin with and are moulded in the tooth, which has been shaped to take and hold the filling. Inlays and onlays are made outside the mouth, usually in a dental laboratory, and then glued to the tooth in the surgery. An inlay sits in a hole in the tooth. An onlay sits on the tooth and builds up its shape. Inlays and onlays can be in tooth-coloured porcelain, gold or a white filling material called composite. Different materials are suitable for different parts of the mouth and different part of the tooth.
