Dentin surrounds the central pulp chamber, which contains blood vessels, nerves, and connective tissue. Dentin is sensitive to touch and to temperature changes. The blood vessels and nerves enter the pulp chamber through the root canals, which are also surrounded by dentin. In the root, dentin is covered by cementum , a thin bonelike substance. Cementum is surrounded by a membrane periodontal ligament that cushions the tooth and attaches the cementum layer, and thereby the whole tooth, firmly to the jaw bone.
