Stomatitis refers to inflammation of the mucous membrane of the mouth, including the inner aspect of the lips, cheeks, gums, tongue and throat. It is a type of mucositis. It can be acute or chronic, mild or serious.
WebMD explains that stomatitis occurs inside any part of the mouth including the cheeks, gums, tongue, lips and palate. Mouth ulcers or aphthous ulcers, herpetic sores and mouth irritation usually cause stomatitis. In addition to gum disease, stomatitis from mouth irritation often stems from biting the cheek, tongue or lip.
