What are mouth ulcers?
Ulcers in the mouth are a common symptom of infection, inflammation, trauma, malignancy, and other underlying conditions and diseases. Mouth ulcers result from pathogens, such as bacteria, viruses and fungi, which inflame the lining of the mouth, causing swelling, redness, and ulcer formation. Ulcers most commonly occur on the inside of the mouth but may also occur on the tongue and lips, or in association with more generalized conditions, such as cancer or hormonal changes. Allergic reactions to food and other substances may also cause inflammation, swelling and development of mouth ulcers.

Canker sore is the name for a painful, open sore in the mouth that is medically known as aphthous ulcer. The sores are not contagious and are small, shallow lesions that develop on the soft tissues in the mouth and gums.
Trauma to the mouth, gums or teeth may result in mouth ulcers due to lacerations. Trauma-related cuts become inflamed, swell, and have the potential develop into a mouth ulcer. Ill-fitting dentures may also cause sores and mouth redness. Any type of trauma to the mouth, lips or tongue can also result in mouth redness as a result of inflammation and swelling around the site of injury.
Damaged to the mouth from hot or spicy foods, chewing tobacco or smoking can cause mouth ulcers. Mouth ulcers may also result from specific medications, including chemotherapy. Underlying conditions that are common causes of mouth ulcers include deficiencies in certain vitamins and minerals and hormonal changes.
