*!The crown of the tooth is that portion of the tooth that is covered with enamel. In most people, the crown lies nearly entirely exposed above the gum line. In children, the gingiva may partially cover the cervical (lower) part of the enamel. Enamel is the substance that covers the crown of the tooth. It is very hard and quite resistant to mechanical and chemical attack. Its purpose, of course, is to protect the tooth from the dangers posed to the teeth by the oral environment.
