FTP, name these anatomical structures important in mastication, types of which include incisors, canines, and molars.
Nerves and blood vessels enter and exit these structures through the apical foramen, and they are anchored by an avascular layer of cementum. They are innervated by the alveolar nerves, and deciduous ones are a good source of stem cells.  Their centers are filled with a soft tissue, pulp, which is covered by a harder tissue known as dentin.  Calculus appears on their outer surface when mineral salts are deposited on already-attached plaque.
