What is a mouth ulcer?
An inflammatory condition characterised by the appearance of an ulcerous lesion on the lining of the mouth (oral mucous membranes), and consequent pain.
Buccal ulcers are small, painful, recurrent surface lesions (similar to small ulcers) which occur on the mobile tissue, hard palate and tongue in the oral cavity: on the inner surface of the lips, the buccal and alveolar mucosa, the tongue, soft palate, oropharynx and floor of the mouth.
They can occur several times (recurrent aphthous ulceration), sometimes in the same place.
The periodic appearance of mouth ulcers is known as Recurrent Oral Aphthous Ulceration (R.O.A.U.).
