Gingiva is the oral mucosa surrounding the neck of each tooth forming the gums.
==Structure and Function of the Gingiva==
Gingiva is mucosal tissue over [[Tooth - Anatomy & Physiology#Alveolar Bone|alveolar bone]]. It has a stratified squamous epithelium, with some keratinisation. It resists friction of food during [[Mastication|mastication]] by being tightly bound to the underlying bone. It recedes with age, exposing the cervical part of the tooth. It is usually salmon pink in healthy animals. A colour change indicates pathology.
===Mucogingival junction===
The '''labiogingival groove''' is the junction between the '''labial border''' and '''gingival line''' on the distal/medial surface of the incisor teeth.
The '''mucogingival junction''' is the junction between the '''attached gingiva''' and '''the free alveolar mucosa'''
==Vasculature and Innervation of the Gingiva==
The gingiva is supplied by the '''superior''' and '''inferior alveolar arteries'''.

Innervation is from the '''trigeminal nerve''' ([[Cranial Nerves - Anatomy & Physiology|CN V]]).
