Oral Ulcers

Mouth ulcers are small painful sores that form in the mouth. The most common type of mouth ulcers are called aphthous or simple ulcers. These are recurrent and often date from childhood and sometimes run in families.


The exact cause of most mouth ulcers is not known.
• Stress or tissue injury is thought to be the cause of simple mouth ulcers. Very often these ulcers are seen appearing in young children and adults during exams.
• A sharp tooth surface or dental appliance, such as braces or ill-fitting dentures, might also trigger mouth ulcers.
• Fruits and vegetables such as citrus, pineapples, apples, figs, tomatoes and strawberries), can trigger a mouth ulcer or make the problem worse.
• Some cases of complex mouth ulcers are caused by an underlying health condition, such as an impaired immune system; nutritional problems, such as vitamin B-12, zinc, folic acid, or iron deficiency and gastrointestinal tract disease, such as Coeliac disease and Crohn’s disease.
• When you first quit smoking, you may develop more mouth ulcers than normal, but this is temporary.
• Medications like common pain killers, Anti-hypertensives and some cardiac medicines may cause a reaction that leads to mouth ulcers.
• Allergic reactions to certain foods and medicines can also cause ulcers.
• Ulcers can sometimes be the first indication of oral cancer; especially ones that are long standing. These should be investigated at the earliest.


You might have a mouth ulcer if you have:
• A painful sore or sores inside your mouth, on the tongue, soft palate (the back portion of the roof of your mouth), or inside your cheeks.
• Ulcers in your mouth that are round, white, or dark grey in color, with a reddish edge or border. In severe mouth ulcer attacks, you may also experience:
• Fever
• Physical sluggishness
• Swollen lymph nodes
• Difficulty in swallowing
Pain from a normal mouth ulcer generally lessens in a few days and the sores usually heal without treatment in about a week or two.

Oral ulcers are easily treatable and the treatment usually includes application of gels which help in faster healing. However, there can be cases where the ulcers are chronic and would need further investigation to identify the exact cause.
