I frequntly get mouth ulsers.what are the reasons and remedies dor it?

Muco cutaneous ulcer: First and foremost, get yourself evaluated for immunodeficiency. Second, peroxide or Chlorhexidine mouthwash once or twice a day helps.

Depends: Some people are sensitive to things like citrus , or stress, or even the kind of toothpaste they use. The most important thing is to try to figure out your triggers to try to stop them. If you can't and you get them that often you would qualify for a daily dose of medication to prevent them. Visit you doctor and discuss this painful problem
