[|Human|] Hi. I am 32 years old and as of 3 weeks ago a smokeless tobacco user.  I have developed a sore/ulcer on my gums under my bottom teeth.  It is not overly painful and seems to be slowly going away.  Is this anything I should be worried about.  I know it is from the repeated use of smokeless tobacco, but does not seem to look like any of the pictures of oral cancer I have seen online.  Just a small open sore.  I have been told that in a week or so time these usually go away, but I just thought Id seek some professional advice.
[|AI|]  Hello, You should feel relief that the area is healing, but this tobacco habit is absolutcputting yourself in a high risk category. Repeat episodes definitely warrant observation by a professional Nd any abnormal tissue will require a biopsy. Please consider Chat Doctor.  Continue to monitor the lesion. Rinse with warm salt water often. Keep your mouth clean with good daily care inuring proper brushing and flossing. Keep well HY
