The pulp is the layer of the tooth that contains nerves and blood vessels. This central part of the tooth is vital for the health and vitality of the tooth, as it is responsible for providing nutrients and sensory function. The nerves in the pulp are crucial in signaling pain and discomfort, which can occur due to various dental issues such as cavities or trauma. The blood vessels within the pulp supply essential nutrients and oxygen to the tooth, helping to maintain its health and function.

In contrast, enamel is the outermost layer, composed primarily of minerals and lacks any nerves or blood supply. Dentin, while located beneath the enamel and containing some nerve endings, does not have its own blood vessels. Cementum covers the root of the tooth and helps anchor it within the jawbone, but like enamel and dentin, it does not contain nerve fibers or a blood supply. Thus, the pulp is distinctly identified as the layer that houses both nerves and blood vessels, making it essential for the overall health of the tooth.
