A canker sore, also known as an aphthous ulcer, is a small, painful lesion that develops on the soft tissues inside the mouth. These sores can appear on the tongue, the inside of the cheeks, the gums, or the roof of the mouth. Canker sores are a common condition, affecting about 20-40% of the population at some point in their lives. They can be quite uncomfortable and may cause difficulties with eating, drinking, and speaking.
The exact cause of canker sores is still unknown, but several factors are thought to contribute to their development. These include stress, minor mouth injuries from dental work, hard brushing, or accidental cheek bites, as well as certain foods and substances that can irritate the mouth. Additionally, some people may be more prone to canker sores due to genetic predisposition or underlying health conditions.

- Stress and anxiety
- Minor mouth injuries
- Certain foods, such as citrus fruits, acidic vegetables, and spicy foods
