Recurrent mouth ulcers that last more than 10 days can be frustrating and uncomfortable. These ulcers are often linked to minor injuries, stress, acidity, or nutritional deficiencies, such as low levels of vitamin B12, iron, or folate. Even though you have used Mucopain and Fefol, they mainly give temporary relief and may not address the root cause, which is why the ulcers keep returning. Regarding treatment, a long-term solution depends on identifying the exact cause. Your doctor may check for vitamin deficiencies, acidity issues, or other underlying conditions and suggest treatment only if needed after proper evaluation. It is not advisable to keep using medicines repeatedly on your own without knowing the reason behind frequent ulcers. To reduce the risk of recurrence, focus on simple daily care. Avoid very spicy, hot, or acidic foods, as they can irritate the mouth. Maintain good oral hygiene and stay well hydrated. Including foods rich in vitamins, especially B-complex and iron, can help support healing. Managing stress and getting enough sleep also play an important role. If ulcers keep recurring or become severe, a thorough check-up can help identify a lasting solution.
