Which Substance is the Outer Covering of the Shell of the Tooth

Question

Which substance is the outer covering of the shell of the tooth in the neck and root?
A) cementum
B) enamel
C) dentin
D) pulp

Accepted Answer

Cementum is a thin, hard layer of tissue that covers the root of the tooth, and it also helps to anchor the tooth to the jawbone. Enamel is the hard, protective outer layer of the crown of the tooth, while dentin is a softer, inner layer of the tooth that lies between the enamel and the pulp. The pulp is the soft tissue inside the tooth that contains nerves and blood vessels.
