Explanation:
Detailed explanation-1: -The gum surrounds the base (root) of the tooth. The root of the tooth extends down into the jawbone. The root contains blood vessels and nerves, which supply blood and feeling to the whole tooth. This area is known as the “pulp” of the tooth.
Detailed explanation-2: -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.
