Which part of a tooth houses blood vessels, nerves, and connective tissue?

The pulp cavity is the central part of a tooth that contains a significant amount of soft tissue, including blood vessels, nerves, and connective tissue. This area plays a crucial role in the overall health of the tooth, providing nourishment and sensitivity. The blood vessels supply essential nutrients, while the nerves enable the tooth to sense pain and temperature changes.

Dentin, enamel, and cementum are structural components of the tooth but do not contain these soft tissues. Dentin gives the tooth its shape and strength, enamel is the hard, protective outer layer, and cementum covers the root surface and helps anchor the tooth in the jawbone. Therefore, the pulp cavity is the only part that includes the necessary components for sensory perception and nutrient supply.
