You may be suffering from a conditions called Aphthous ulcers. The cause of aphthous ulcers is not clearly known. It is known that there is a genetic basis for this. Stress can trigger the formation of these ulcers. Some individuals may suffer from aphthous ulceration due to an allergic reaction. This reaction may be to a new toothpaste, mouthwash or a food item. Vitamin B12, folate or iron deficiency is also known to cause aphthous ulceration. There are some major systemic disorders that can present with aphthous ulceration. Supplements of vitamin B12, folate and iron may relieve your problem. Try to figure out if there is any stressful event, foodstuff, or a certain toothpaste or mouthwash that triggers off the ulceration. Avoiding these can relieve your problem. If none of these work, you should consult your doctor for a more detailed workup to find out if there is any other cause for your ulcers. In the meantime, you should avoid spicy food during your attacks. Use of a pain relieving gel (commonly available as mouth ulcer gels) can temporarily relieve the pain you experience while eating.
