Editing Teeth (section)

==Anatomical Structure==
A tooth is divided into two primary parts:
* '''Crown''': The visible portion of the tooth above the [[gingival margin]].
* '''Root''': The portion embedded within the alveolar bone, anchored by the [[periodontal ligament]].
* '''Cervix (Neck)''': The slight constriction at the junction of the crown and the root ([[Cementoenamel junction]]).

===Tissue Layers===
A tooth is composed of four distinct tissues:
# '''[[Enamel]]''': The hardest substance in the human body. It is highly mineralized (96% hydroxyapatite) and covers the crown. It is non-vital and cannot regenerate.
# '''[[Dentin]]''': Located beneath the enamel and cementum. It is a vital, mineralized tissue that contains microscopic '''[[dentinal tubules]]'''.
# '''[[Dental pulp]]''': The unmineralized central chamber containing loose connective tissue, blood vessels, and nerves.
# '''[[Cementum]]''': A bone-like mineralized tissue covering the root surface, providing attachment for the [[periodontal ligament]].
