Mouth ulcers, also known as aphthous ulcers, are small, painful sores that appear on the inside of the mouth, tongue, or lips. They are quite common and can be caused by a variety of factors.

In this article, we will discuss the top 4 causes of mouth ulcers.

1. Trauma

A common cause of mouth ulcers is trauma to the inside of the mouth. This can happen if you accidentally bite your cheek or tongue, or if you have a sharp tooth or orthodontic appliance that rubs against the inside of your mouth.

Certain foods like nuts, potato chips, and some fruits can also cause small cuts in the mouth that can lead to ulcers.

2. Stress

Stress is another common cause of mouth ulcers. It is believed that stress can weaken the immune system, making it more susceptible to infections and injuries.

When a person is stressed, their body releases chemicals that can cause inflammation and irritate the lining of the mouth, leading to the development of ulcers.

3. Bacterial or Viral Infections

Mouth ulcers can also be caused by bacterial or viral infections. For instance, herpes simplex virus can cause cold sores, which are a type of mouth ulcer. Other bacterial infections that can cause ulcers include streptococcus and staphylococcus.

These infections can be spread through saliva and close contact with someone who is infected.

4. Nutritional Deficiencies

Nutritional deficiencies, such as deficiencies in vitamin B12, iron, and folate, can also cause mouth ulcers. These vitamins and minerals are important for maintaining healthy cells in the body, including the cells that line the inside of the mouth.

A deficiency in these nutrients can lead to a breakdown in the lining of the mouth and the development of ulcers.

Conclusion

Mouth ulcers can be a painful and frustrating condition. Knowing the causes of ulcers can help you prevent them from occurring in the first place.

If you do develop a mouth ulcer, it is important to practice good oral hygiene and avoid foods and drinks that can irritate the sore. If the sore persists for more than a week or becomes very painful, it is recommended that you see a doctor or dentist for treatment.
