Contact stomatitis is inflammation or pain of the oral mucosa caused by external stimuli.[1] It is characterized by cutaneous lesions that may be located where the offending agent contacts the mucosa for a prolonged time.[2] Oftentimes it presents in the mouth after contact with hot food or from ill-fitted dentures or other irritant. Consequently, patients may seek resolve from their dentist rather than a dermatologist. Unlike with allergic contact stomatitis, the skin requires no previous exposure to a stimulant before crafting an immune reaction.
