    it is the portion of the tooth where the enamel meets the Dentin. This would be in the anatmical crown of the tooth.
  46. What is Pulp ?
    The living tissue that occupies the pulp cavity of the tooth.It contains the nutrient supply that comes from blood vessels. It also has the nerve supply.
