Explanation:
Detailed explanation-1: -A dental crown is a tooth-shaped “cap” which is placed over a tooth to cover the tooth to restore its strength, size and shape and correct its appearance. The crowns are cemented into place after which they completely encase the entire visible portion of a tooth that lies above the gum line.
Detailed explanation-2: -The crown is the top part that is exposed and visible above the gum (gingiva). It is covered with enamel, which protects the underlying dentine. The root of a tooth descends below the gum line anchoring the tooth in the mouth. The neck is the dividing region of tooth at the gum line, where the crown meets the root.
