Possible causes for recurrent ulcers in mouth are emotional stress, vitamin B-12, zinc, folate or iron deficiency, certain foods or allergens etc. Try to avoid foods that seem to irritate your mouth. Follow good oral hygiene habits. Eat healthy foods like fruits, vegetables and whole grains. Use stress-reduction techniques, such as meditation.

Maintain good oral hygiene. Apply kenakort ointment
