Structure of the human teeth
The human tooth is made up of hard and soft structures. The enamel, dentin and the cementum make up the hard structures. The pulp and the gums constitute the soft structures. The entire tooth is held to the surrounding bone by the periodontal ligament. The pulp is the living structure as it contains the nerves and the blood vessels. The pulp also contains the cells the generate the tooth material. Hence, any damage to the pulp means the death of the tooth.
