Which term describes the calcified tissue that forms the majority of the tooth's interior under the enamel?

• A. Pulp
• B. Enamel
• C. Dentin
• D. Cementum

Answer: (C)

The main idea is identifying the tissue that makes up the tooth’s bulk beneath the enamel. Dentin is a calcified tissue produced by odontoblasts that forms the vast majority of the tooth’s interior just under the enamel. It provides most of the tooth’s structure and resilience, and it contains dentinal tubules that extend toward the pulp, which explains sensitivity when dentin is exposed. Enamel sits as the hard outer layer, protecting the tooth; pulp is the soft tissue inside housing nerves and blood vessels; cementum covers the root surfaces. So, the tissue that forms most of the interior beneath the enamel is dentin.
