Canker sores are common painful sores that can develop in the mouth. The exact cause of canker sores is not always clear, but several factors contribute to their development. One of the main causes is minor trauma to the soft tissues in the mouth, such as accidental bites, aggressive brushing, or rubbing the gums or cheeks with braces. In addition, stress and anxiety can weaken the immune system, making people more susceptible to these injuries.

Some foods can also cause cancer, such as acidic fruits, spicy foods, and foods rich in citrus fruits.In addition, a lack of essential nutrients such as vitamin B12, iron or folic acid can lead to their occurrence. Also, some people can develop cancerous growths as a result of allergic reactions to certain substances, such as toothpastes or mouthwashes, that contain harsh chemicals.


Although canker sores are not contagious, they can be painful and take a week or more to heal. Fortunately, most cases go away on their own without medical intervention. However, recurring or persistent sores should be evaluated by a doctor to rule out possible underlying conditions. Good oral hygiene, managing stress, and avoiding trigger foods can help reduce the likelihood of those uncomfortable sores in the future.
