The pulp is the most vital part of the tooth. The pulp originates in the very center of the tooth, located underneath the enamel and dentin in what is referred to as the pulp chamber. The pulp is also known as the nerve of the tooth and also contains blood vessels, connective tissue, and the large nerves. The nerves branch out and continue down into the roots of the tooth. The pulp has many functions including: sensory function, formation of dentin, and nourishment. Tooth decay, infection, or any sort of trauma can cause inflammation of the pulp, which is generally treated with a root canal. When a root canal is performed, the pulp is removed from the tooth and the tooth is then considered dead.
