Gingiva wrap around the neck of each tooth forming the gums. The gums are useful clinically in assessing health status of an animal.

Gingiva is the oral mucosa surrounding the neck of each tooth forming the gums.

==Structure and Function of the Gingiva==

==Structure and Function of the Gingiva==

*Mucosal tissue over [[Alveolar Bone|alveolar bone]]

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.

The '''mucogingival junction''' is the junction between the '''attached gingiva''' and '''the free alveolar mucosa'''

 

Labiogingival Groove is the junction between the labial border and gingival line on distal/medial surface of the incisor teeth.

==Vasculature and Innervation of the Gingiva==

==Vasculature and Innervation of the Gingiva==

*Superior and inferior alveolar arteries  

The gingiva is supplied by the '''superior''' and '''inferior alveolar arteries'''.

*Blood vessels in the dental [[Pulp - Anatomy & Physiology|pulp cavity]] and a single branch in each major elevation of the [[Crown|crown]]

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