The answer to the question: The part of the tooth that is covered with enamel, would be: the crown of the tooth.
Explanation:
The human teeth are divided into two parts, a hardened one, which is the one we can see protruding from the gum line, and which is the one that we use to bite, pounce food and chew it before swallowing. This portion of the tooth is called the crown, it is the white, hardened, visible part, and it is covered with enamel to protect it from the mechanical and corrosive forces of both food, and saliva, as well as bacteria. The second portion of the tooth is known as the root, and it is the softer part that is protected and covered by the gums. The root anchors the tooth to the bone structures of the mandible and maxilla.

If an exchange transfusion does become necessary, type O blood is used or treatment with phototherapy.
