what are causes of canker sores
Deficiencies of calcium can also cause canker sores, but more than causing them, calcium deficiency can worsen the situation. Healthy eating is the best solution to such a nutritional deficiency. 3. Stress/injury. Stress on the tissues or any type of injury in the mouth can cause canker sores. Since the sores are actually tiny ulcers, they can be caused by any kind of hard brushing or eating something that can cause bruises or lead to tissue inflammation in the mouth.
