How are Mouth Ulcers Caused?

Mouth ulcers, also known as canker sores or aphthous ulcers, are small, painful sores that develop inside the mouth. While the exact cause of mouth ulcers is not always clear, they are believed to result from a combination of factors, including:

  1. Trauma or Injury: Minor injuries to the mouth, such as accidentally biting the inside of the cheek, using a toothbrush with hard bristles, or sharp foods like potato chips, can trigger the development of ulcers.
  2. Stress: Emotional stress or physical stress on the body can weaken the immune system, making it easier for mouth ulcers to form.
  3. Certain Foods: Some people may be sensitive or allergic to certain foods, such as citrus fruits, spicy foods, or highly acidic foods, which can lead to the development of mouth ulcers.
  4. Dietary Deficiencies: A lack of certain nutrients, such as vitamin B12, iron, and folic acid, can contribute to the formation of mouth ulcers.
  5. Hormonal Changes: Hormonal changes, particularly in women, can sometimes trigger the development of mouth ulcers.
  6. Autoimmune Reactions: In some cases, the body’s immune system may mistakenly attack the cells in the mouth lining, leading to the formation of ulcers.
  7. Genetics: There seems to be a genetic predisposition to developing mouth ulcers. If your parents or other family members have a history of mouth ulcers, you might be more prone to them.

It’s important to note that while these factors can contribute to the development of mouth ulcers, they are not definitive causes for everyone. Mouth ulcers are generally not contagious, and most of the time, they heal on their own within a couple of weeks. However, if you experience persistent or severe ulcers, it’s a good idea to consult a healthcare professional for proper diagnosis and treatment.
