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.
During this first office visit your dentist will make a temporary crown to cover and protect the prepared tooth while the crown is being made. Temporary crowns usually are made of acrylic and are held in place using a temporary cement. Second Visit: Receiving the permanent dental crown.
