What causes painful white mouth sores?


Answer by  sbeers1 (15)

Painful, white sores inside the mouth may be caused by accidental biting or puncturing of the inner cheek. The oral cavity stays wet, causing the injury to be slow in the healing process. Also, while healing, the immediate area of the injury swells, making it more easily contacted repeatedly. Any food item may also cause a burning sensation.

If they keep happening even though you are on a relatively healthy diet it may be a symptom of an auto immune disease. You should mention this to your doctor on your next check up. You can wash your mouth with water mixed with baking soda for temporary relief.

The most common sores are canker sores. Canker sores can be very painful, but are not contagious. Canker sores can be caused by fatigue, stress, or allergies. Some poeple are more prone to canker sore but doctors are unsure why. They are sometimes caused by bacteria, braces, or a sharp tooth. They can also be sometimes a symptom of disease.

Painful white mouth sores can be caused by many things. They can be caused by thrush, not having enough vitamins, eating something too spicy or too sour, or it could be something more serious. It would depend on exactly where in the mouth the sores are, how big they are, and how sore they actually are.
