The oral cavity is the vestibule of the digestive system structured to contain and mechanically process food. It also initiates digestion and facilitates ingestion and deglutition. It includes the lips, the tongue with its taste buds, a large number of glands that moisten the mucosa. The saliva produced by the salivary glands facilitates mastication and ingestion of food. The oral cavity also has two rows of teeth structured to grasp, cut and grind hard food, permitting their ingestion. Teeth are remarkable mineralized tools that are well inserted and attached to bones. They are formed in two waves during development through a process of differentiation of tissues of epithelial and connective tissue origin. The present chapter includes the histological characteristics of the various organs mentioned above and attention will be given to the formation of teeth.
