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

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

− | ==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. |
