Oral mucosa

The oral mucosa is located on the inside of the oral cavity and covers it completely. The part of the oral mucosa around the teeth is called “gum”.

The oral mucosa, which consists mainly of connective tissue, contains some lymphocytes (defence cells). The mucosa is covered by a squamous epithelium. The oral mucosa contains sensory cells for temperature, pain and touch. Where the mucosa is subject to greater stress during chewing, it is somewhat harder than in unstressed areas.
