<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have mouth ulcers on my gums and tongue. I have been to 4 different doctors and a dentist. They are continuously in my mouth now for 1 year and a half. I know that they are not herpectic as they have been cultured, but no one knows what is causing them and no medicine or remedy that I have used helps. Do you have any suggestions?  <response>: Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have ulcers on gums and tongue dont worry you can do warm saline gargle two - three times a day Apply ointment Gum paint on painful Gums twice daily for one week Apply ointment McCoppin or Colonel on ulcers two - three times a day for one week Take one vitamin B complex once daily for 7 days Take Fiber rich diet avoid junk food.
