Crowns cover the entire surface of your tooth. They are used to protect existing teeth and/or improve their appearance. They are usually made of porcelain and may have a gold core. To fit the crown the size of your existing tooth will be reduced to make enough space for the crown and then a mould is made for the dental technician. A temporary crown will be fitted until the dental technician has made yours. They are typically bonded to the tooth using dental cement.
As new technology has evolved, computers are increasingly becoming a part of crown and bridge fabrication, such as in CAD/CAM Dentistry and used in Cerec® treatments.
