When to Seek Medical Care

You should seek medical attention if any of the following occur:

  • It is your first episode and you are not sure about the diagnosis.


  • The pain worsens and you cannot control it.


  • You have diarrhea. This may indicate you are having a systemic problem like Crohn's disease or ulcerative colitis.


  • You have ulcers in places other than the mouth. This may indicate that you have a disease called Behçet 's syndrome or possibly a sexually transmitted disease.


  • Lesions persist beyond three weeks.


    • Lesions lasting over three weeks raise the concern for oral cancer or inflammatory bowel disease (ulcerative colitis or Crohn's disease).


    • Factors that may increase the risk of oral cancer include smoking, tobacco chewing, and use of alcohol.
