Frequent mouth ulcers (recurrent aphthous stomatitis) require both pain relief and proper medical investigation. For immediate pain relief, you can use over-the-counter topical anaesthetic gels containing lidocaine or benzocaine. To accelerate healing and reduce inflammation, a prescription topical steroid paste, such as triamcinolone acetonide, is highly effective when applied early. Since your ulcers recur every 10 to 20 days, it is crucial to consult a doctor or dentist. They should perform blood tests to rule out underlying causes like vitamin deficiencies (B12, folate, and iron), celiac disease, or immune system issues, which will help guide a long-term preventive treatment plan.

Painful mouth ulcers in children are quite common and are usually caused by minor infections, stress, accidental biting, irritation from spicy or acidic foods, or sometimes nutritional deficiencies like low iron, vitamin B12, or folic acid. In some cases, viral infections can also trigger multiple ulcers at once, making eating and drinking uncomfortable. At home, giving soft, cool foods like curd, porridge, and banana, and avoiding spicy or citrus foods can reduce irritation. Keeping her well hydrated is important because dehydration can delay healing. Gentle mouth rinsing with plain water after meals can also help keep the area clean. Over-the-counter soothing gels or oral ulcer pastes are often used to reduce pain and help with eating, but it is better to choose them based on a doctor or pharmacist's advice for her age. If pain is severe, a doctor may prescribe mild pain relief or vitamin supplements depending on the cause. If ulcers are frequent, very large, last more than a week, or are associated with fever or weakness, she should be examined to rule out underlying deficiencies or infections.

Oral Submucous Fibrosis causes stiffness of the mouth tissues and restricted tongue movement, and the most important step is to completely stop chewing tobacco, gutkha, or areca nut. Treatment may include medications and supplements (like antioxidants and vitamins), and sometimes doctor-given injections to reduce fibrosis. Regular mouth-opening exercises and physiotherapy are very important to improve movement. In severe cases, surgical treatment may be needed. Regular follow-up with a doctor or dentist is essential, as this condition needs monitoring.
