There are plenty of possibilities to replace one or several lost teeth. An implant is usually the best way to replace a single missing tooth. A fixed crown or a dental bridge can be used to replace missing teeth or to repair a tooth that has been subject to root canal treatment, to better withstand bite forces. A single crown or bridge is usually made of tooth-coloured ceramic material. It is also possible to replace several missing teeth with a removable partial denture. Its frame may be made of metal or plastic.
