Collectively all the soft tissues of the mouth are known as oral
mucosa.
Oral mucosa – 3 zones :-
1) Masticatory mucosa = Gingiva + covering of hard
palate
2) Specialized mucosa = Dorsum of tongue + taste buds
3) Lining or reflecting mucosa = oral mucous membrane lining
the remainder of oral cavity (lip,cheek,vestibular
fornix,alveolar mucosa,floor of mouth,soft palate)

Definitions :-
- It is the part of oral mucosa that covers the alveolar process of the jaws and surrounds the necks of the teeth. (Carranza 2003)
Anatomically it consists of three types of gingiva
•Marginal gingiva•Attached gingiva•Interdental gingiva
