Tooth crowns. A tooth crown or dental crown is a tooth-shaped sleeve made of porcelain or metal or a combination of both that is placed over a tooth. The dentist will match it up to the shape and colour of your other teeth.
A crown is a cap on a tooth. It looks like a cylinder that fits over the tooth after it has been prepared by a dentist. It is used to fix a tooth that has been severely broken or decayed to restore it to the proper shape, size, and color. It can also be used cosmetically to change the shape, size, and color of a tooth.
