Tooth Anatomy
CementumCementum is a specialized bony substance covering the root of a tooth
CrownCrown refers to the anatomical area of teeth, usually covered by enamel. The crown is usually visible in the mouth after developing below the gingiva and then erupting into place.
DentinDentin is the substance between enamel or cementum and the pulp chamber. It is secreted by the odontoblasts of the dental pulp
EnamelEnamel is the hardest and most highly mineralized substance of the body
Gums (gingiva)Gingiva are part of the soft tissue lining of the mouth. They surround the teeth and provide a seal around them.
NeckThe narrowed part of a tooth between the crown and the root
Periodontal LigamentThe periodontal ligament, commonly abbreviated as the PDL is a group of specialized connective tissue fibers that essentially attach a tooth to the alveolar bone within which it sits.
PulpThe dental pulp is the central part of the tooth filled with soft connective tissue. This tissue contains blood vessels and nerves that enter the tooth from a hole at the apex of the root.
RootsThe lower two-thirds of a tooth. The roots are normally buried in bone, and serve to anchor the tooth in position. They are covered with a thin layer of bone, and insert into sockets in the bone of the jaw. |
