Which component of the tooth is known for its soft tissue characteristics?

Dentin
Cementum
Pulp
Enamel

The correct answer is: Pulp

The pulp is known for its soft tissue characteristics because it contains a rich supply of blood vessels and nerves. This central part of the tooth is crucial for its vitality, housing connective tissues, cells, and the nerve endings that provide the tooth with sensory functionality. The pulp serves several important roles, including nourishing the tooth, aiding in repair and maintenance, and contributing to the formation of dentin through odontoblasts, which are specialized cells located at the border of the pulp. In contrast, dentin, cementum, and enamel are all harder tissues. Dentin is calcified and is the main body of the tooth beneath the enamel. Cementum is a bone-like tissue covering the roots, helping anchor the tooth to the jawbone. Enamel is the hardest substance in the human body, providing a protective outer layer for the tooth.
