Stomatitis is inflammation of the mouth and lips. It refers to any inflammatory process affecting the mucous membranes of the mouth and lips, with or without oral ulceration.

In its widest meaning, stomatitis can have a multitude of different causes and appearances. Common causes include infections, nutritional deficiencies, allergic reactions, radiotherapy, and many others.

When inflammation of the gums and the mouth generally presents itself, sometimes the term gingivostomatitis is used, though this is also sometimes used as a synonym for herpetic gingivostomatitis.

The term is derived from the Greek stoma (στόμα), meaning "mouth", and the suffix -itis (-ῖτις), meaning "inflammation."

Malnutrition (improper dietary intake) or malabsorption (poor absorption of nutrients into the body) can lead to nutritional deficiency states, several of which can lead to stomatitis. For example, deficiencies of iron, vitamin B2 (riboflavin),vitamin B3 (niacin), vitamin B6 (pyridoxine), vitamin B9 (folic acid) or vitamin B12 (cobalamine) may all manifest as stomatitis. Iron is necessary for the upregulation of transcriptional elements for cell replication and repair. Lack of iron can cause genetic downregulation of these elements, leading to ineffective repair and regeneration of epithelial cells, especially in the mouth and lips. Many disorders which cause malabsorption can cause deficiencies, which in turn causes stomatitis. Examples include tropical sprue.

Aphthous stomatitis (canker sores) is the recurrent appearance of mouth ulcers in otherwise healthy individuals. The cause is not completely understood, but it is thought that the condition represents a T cell mediated immune response which is triggered by a variety of factors. The individual ulcers (aphthae) recur periodically and heal completely, although in the more severe forms new ulcers may appear in other parts of the mouth before the old ones have finished healing. Aphthous stomatitis is one of the most common diseases of the oral mucosa, and is thought to affect about 20% of the general population to some degree. The symptoms range from a minor nuisance to being disabling in their impact on eating, swallowing and talking, and the severe forms can cause people to lose weight. There is no cure for aphthous stomatitis, and therapies are aimed at alleviating the pain, reducing the inflammation and promoting healing of the ulcers, but there is little evidence of efficacy for any treatment that has been used.
