− | *Mucosal tissue over [[Alveolar Bone|alveolar bone]]
| + | Gingiva is mucosal tissue over [[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. |
