Oral Mucosa

The moist, pink mucous membrane lining the inside of the mouth, including the cheeks (buccal mucosa), lips, and soft palate.

Why It Matters

It acts as a barrier against pathogens. Changes in the mucosa—such as ulcers, color changes, or rough patches—are often the first signs of systemic diseases (like anemia or lichen planus) or oral cancer.

Clinical Details

• Types: Masticatory (tough, on gums/palate), Lining (stretchy, on cheeks/floor of mouth), and Specialized (taste buds on tongue).
