Hi Joey,

I agree with the other posters in having this checked by a qualified ENT. That being said, cancer is an uncontrollable growth of abnormal cells. Once it starts, it doesn't just stop and hang out. The fact that this "sore" has been there for months, even years, your dentist thinking it's an irritation due to an inherit dental issue along with your age bodes well that it's nothing sinister.

Definitely have it checked. Best wishes for an "all clear" from the doctor.

Positive thoughts and prayers
