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.

Mouth sores for a few days are often caused by minor injury, stress, spicy food, or a vitamin deficiency. Rinsing the mouth with warm salt water and avoiding very spicy or acidic foods may help reduce irritation. Your doctor may advise topical gels or vitamin supplements to support healing. Consult a doctor if the sores are very painful or do not improve within a week.

See a dentist as soon as possible to determine if you need a filling or other treatment for your toothache. In the meantime, you may take over-the-counter painkillers such as paracetamol or ibuprofen. Avoid eating very hot, cold, or sugary foods, and maintain oral hygiene by gently brushing and flossing to help prevent worsening of your condition.

An under-tongue ulcer usually heals on its own in 7 to 10 days. Keep your mouth clean, avoid spicy or hot foods, and drink plenty of fluids. You can use a soothing oral gel or mouth ulcer gel and rinse with warm salt water. If the ulcer is very painful, lasts more than 2 weeks, or keeps coming back, please see a doctor or dentist for further check-up.

Yes, benzocaine can be used for oral ulcers to help numb the pain and make eating or talking more comfortable. See a doctor if ulcers persist for more than a week or are very painful.

Yes, this is likely an infection. A water blister on your lip is commonly a cold sore (a viral infection), and the soft, movable lump under your jaw is likely a reactive, swollen lymph node fighting it off. Since cold sores are viral, antibiotics will not work. You can treat the blister with over-the-counter gels (like Benzocaine) or consult a doctor for prescription oral antivirals (like acyclovir) to speed up healing. Use ibuprofen for any pain, and avoid popping the blister. If the lump under your jaw grows, becomes hard, or persists after the blister heals, please see a doctor for a physical exam.
