Detailed explanation-1: -The crown is the part of the tooth that you can see above the gums. The root is the part of the tooth that is below the gums. The top layer of the crown is enamel. Below the enamel is dentin, which surrounds the pulp .
Detailed explanation-2: -Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown’s porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede.
Detailed explanation-3: -The upper part of the human tooth is called crown while the lower one is root. Incisors and canines have one fang, premolars have two and molars have three fangs. All types of teeth have the same general structure.
