Contact stomatitis is inflammation or pain of the oral mucosa due to both irritant and allergic substances. Irritants include heat, frictional trauma, and chemicals. Oral flavorings, preservatives, and dental materials are common allergens. Simplification of oral care and avoidance of contactants is the primary mode of therapy. Patch testing to a broad series of antigens may be required to identify specific causes of allergic contact stomatitis.
