Mouth ulcers are the sores that appear inside the mouth. Why does a mouth ulcer come? This might be the common question arising in the minds of many people. Usually, mouth ulcers occur due to several reasons like biting of the cheek, improper Orthodontic appliance fitting in the mouth, intestinal problems, and some other reasons.

What are the common causes of mouth ulcers?

Usually, a single mouth ulcer is mainly due to damage caused by accidentally biting the cheek or tongue, sharp teeth, tooth brushing or poorly fitting dentures. These ulcers are called ‘ traumatic ulcers.’
If you have more than one mouth ulcer that’s because of ‘ recurrent aphthous stomatitis.

How do l know if I have a traumatic ulcer?

Traumatic ulcers are generally on their own, are next to the cause of the damage and go away once the source of the problem is solved.

What are the sings of recurrent aphthous stomatitis?

Are there different types of recurrent mouth ulcers?

Minor ulcers are the most common. They can appear inside the cheeks, on the lips, tongue, and gums, and, more rarely, on the roof of the mouth. Most of these ulcers are in the size of the top of a pencil and sometimes come in clusters. You can get four to six at any one time.

Large ulcers are more severe and can last for five to ten weeks. They can appear near the tonsils, and that can be very painful, mostly when swallowing. You usually only get one at a time. There is also a possibility of 100 tiny painful ulcers appearance which lasts for one to two weeks.

However, these last two varieties are very rare.

You can also get ulcers in other body parts like your eyes or genital area. It is important to tell your dentist about these ulcers are sores that appear inside the mouth.

What are the less common causes of mouth ulcers?

Infections can cause mouth ulcers. Herpes simplex often leads to widespread mouth ulcers in children and some adults. Other less common viral and bacterial infections can also cause mouth ulcers, but this happens very rarely.


Mouth ulcers can be caused occasionally and occasionally by other blood disorders and some skin or gastrointestinal diseases. In some cases, mouth ulcers are the only sign of an underlying illness.

Ulcers caused by cancer frequently appear on or under the tongue, but can occasionally look somewhere else in the mouth.
Cancer of the mouth is usually associated with heavy smoking and drinking. Doing both together greatly increases the risk.
