Most ulcers are painful sores inside the mouth, and are usually red or yellow in colour. Mouth ulcers are different from cold sores, which appear on the outer lips and are due to a virus. A single mouth ulcer is usually caused by biting the cheek or tongue, sharp teeth, tooth brushing or poorly fitting dentures. These traumatic ulcers disappear over time. If the problem persists our specialised team is available to offer advice on how some of our treatments can help. Sometimes, multiple mouth ulcers are caused by recurrent aphthous stomatitis. Recurrent aphthous stomatitis is a common problem and causes repeated bouts of mouth ulcers in otherwise healthy children and young people. The cause is not known, but it is not infectious and is unlikely to be inherited. If an ulcer lasts more than 3 weeks contact us for diagnosis and treatment or referral to a specialist.
How can I prevent mouth ulcers?
