Hi, usually common oral ulcers will go on its own after some days. If it is not going, if it is chronic, we have to rule out the causes like continuous injury during chewing, premalignant conditions, If it is below tongue fluid filled it may be due to ranula. Go for microscopic pathology of blister mucosa, cbc, consult general physician for complete evaluation.
