Reactions to contact with various substances may be allergic or primary irritant in nature. Allergic stomatitis is characterized by erythema and oedema, combined with a burning sensation, loss of taste, and numbness rather than itching. Vesiculous lesions are rarely evident because of quick rupturing. Irritant reactions are usually due to heat or chemical injury and may cause erythema, vesicles, and bullae, resulting in painful erosions.
