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.
The crown. This is the part of the tooth that we see in the mouth. It is made up of the enamel, dentine and pulp. The appearance of teeth varies in shape and size.
