Treatment:

The goal of treatment is to relieve symptoms. The cause, if known, should be treated.

Gentle, thorough oral hygiene may relieve some of the symptoms. Topical (rubbed on) antihistamines, antacids, corticosteroids, or other soothing preparations may be recommended for applying directly to the ulcer.

Avoid hot or spicy foods, which often increase the pain of mouth ulcers.

Expectations (prognosis):

The outcome varies depending on the cause of the ulcer. Many mouth ulcers are harmless ( benign)and heal without treatment. Sometimes, mouth cancer first appears as an ulcer that won't heal.

Complications:

• Cellulitis of the mouth, from secondary bacterial infection of ulcers
• Dental infections (tooth abscesses)
• Oral cancer
• Spread of contagious disorders to other people

Calling your health care provider:

Call for an appointment with your health care provider if your mouth ulcers don't go away after 3 weeks. Call for an appointment with your health care provider if mouth ulcers return frequently, or if new symptoms develop.
