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.
It encases the tooth and becomes the tooth's new outer surface. You may need two or more visits to your dentist to repair a severely decayed tooth with a crown. Crowns may be made of porcelain or a metal base covered with a thin layer of ceramic that matches your teeth and looks like a normal, healthy tooth. Crowns for the teeth in the back of the mouth may be made of gold. During your first visit, your dentist will take out the decay and make an impression of your teeth to create a mold used for making the crown. Your dentist will: Numb your teeth, gums, tongue, and surrounding skin.
