I have to tell you that I noticed a slight burning irritation when consuming some foods, liquids, or chewed gum, etc . . . I never used mouthwash, just flossed & used toothpaste. I noticed that in the area of my tongue before the ulcer appeared. That was my only sign that anything was amiss before the ulcer. By itself I did not think it meant much, apparently it did.

If you indeed have a problem there the good thing is you should be able to catch it early. Find a good ENT though, one that sees oral cancer.

Best,
Anne
