How to treat the ulcer on the tongue should be considered in three situations: first, the most common recurrent aphthous ulcer is recurrent, which can heal itself in about 1-2 weeks each time, and will recur after a period of time. The number of recurrent ulcers varies with the location of each recurrent ulcer. The ulcer on the tongue is difficult to cure, and symptomatic treatment will be taken, including local spraying. Second, traumatic ulcer may be caused by careless biting or eating some sharp food, or it can heal itself. But some patients will develop ulcers for a long time. The treatment method is the same as recurrent oral ulcer, and it is also symptomatic treatment to avoid local traumatic infection. Third, the most serious one is called cancer ulcer, which lasts for a long time and grows gradually. The pain is also severe, and it may also affect the movement of the tongue. The clinical manifestations of cancer ulcer are not only ulcers, but also hard infiltrating nodules and masses around the basement. You should go to the hospital for examination in time, take a biopsy to make a definite diagnosis, and then decide whether to do radical surgery for treatment.
