For mouth ulcers, commonly used medicines include topical gels like Dologel CT or Hexigel, which help reduce pain and promote healing. Most ulcers heal in a few days, but if they are severe or keep coming back, it?s best to consult a doctor for proper treatment.

Mouth ulcers for 2 days are usually minor and can occur due to stress, spicy food, or accidental cheek bites. They often heal on their own within a week, so you can use warm saltwater rinses. If the ulcers are very painful, large, or last more than 1?2 weeks, it?s better to consult a doctor.
