What are sperm whales teeth made of?

In: Sperm Whales [Edit categories]

Answer:

A sperm whale possesses teeth with cementum cells overlying dentin cells. Unlike human teeth (which are comprised mostly of enamel on the tooth portion outside of the gum) sperm whale teeth have cementum outside the gum. Only in larger whales does some enamel show where the cementum has been worn away on the tip of the tooth, revealing the underlying enamel.
