Q

Teeth are composed of bone.

True or False?

A

False. Teeth are composed of four dental tissues. Three of them—enamel, dentin and cementum—are hard tissues. The fourth tissue—pulp, or the center of the tooth that contains nerves, blood vessels and connective tissue—is a soft, or non-calcified, tissue

The misconception that teeth are the same as boon can be due to the fact that they both contain calcium
