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.
What is a Post Crown? A post crown is a combination of a post (that extends down into the root canal of your tooth) and a dental crown. There is actually a third element called the 'core'.
