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 body of a tooth is made of dentin with the crown covered by enamel, one of the hardest substances produced in nature. Inside the tooth, is a soft tissue called the pulp containing blood vessels, nerves and connective tissue, which creates the surrounding dentin and enamel during growth and development. The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root.
