Answer
Dear Lester,

It sounds like you have an ulcer. I do not understand from your question exactly where the ulcer is, but the standard rule of thumb is that if the ulcer doesn't go away in two or three weeks, most dentists consider ordering a biopsy.  Sometimes benign ulcers can take a while to heal, especially if they are immediately over the bone.  Although most lesions are benign, occasionally an ulcer can turn out to be a malignancy. I recommend you visit a dentist.

If you haven't had a cleaning in over 6 months, it time.  Ask the dentist to examine the white spot and make a recommendation. If you can not afford a cleaning, then go for a consultation.  

If you do not have a regular dentist and you could start with a visit to an Oral Surgeon. Most Oral Surgeons have extra experience at diagnosing oral lesions and often they perform any needed biopsies. If you go to the oral surgeon first you may save the additional fee of seeing a general dentist.

I hope this information is helpful and please feel free to contact me again with any future dental questions.
