Explanation:
Detailed explanation-1: -Dentin (hard tissue): Most of the tooth is made up of dentin, which sits beneath the enamel to provide extra support (especially while eating). Dentin is calcified tissue that’s tough like bone, but also has a degree of compliance to it (not stiff). It’s not as hard as enamel, and is more vulnerable to wear.
Detailed explanation-2: -Cementum: The cementum is a layer of hard tissue that covers the root of the tooth. It is roughly as hard as bone but considerably softer than enamel.
