So the oral surgeon did not do a biopsy? From what I read you've had some sores for a few years already. Yes, the red area can be from a root canel, so I'm glad you are getting that checked out. Personally I would not be confortable waiting an additional 6-9 months to get it checked out again.

I was a non-smoker, moderate drinker and developed a painful canker sore on my tongue. I also had a lot of strep throat infections during my life and actually I thought the painful spots was due to strep again (had sore throat and fever). After it appeared (and wasn't really bothering me), I went for my regular dental check-up and cleaning. My dentist at the time did not mention the canker sore or do an OC screening.

When the sore still presisted, and I did some research on my own, and saw the words "cancer" I made an appointment with my primary care physicain. He said he has seen a few cases of OC, but my spot didn't present as any he had seen (plus I didn't have any risk factors). But he suggested I go to an oral surgeon if it didn't go away in a few weeks (gave me some topical medicine to use).

I waited about 1 week and made an appointment with an oral surgeon. I got the same response from him, but he did schedule me for a biopsy. I think he was more surprised than I was when he told me that little white spot was cancer!

If you want another opinion, consider attending one of the many OCF Awareness Events that are held around the country. A list can be found by clicking on the "More Ways to Help OCF" link that should be visible on the upper right side of this page. All OCF events offer free oral cancer screenings by dental professionals and some ENTs. The cost to attend the OCF events runs around $25 and supports a great organization. (Which supports this forum you are using).

You mentioned some issues with swallowing or the feeling os something in your throat. Did the oral surgeon address this problem? I don't believe they cover this issue or examine the throat, but an ENT does. An ENT can scope your throat in your office - an unpleasant procedure, but not painful.

I'm glad you quit smoking! Tobacco use contributes to a lot of health issues, plus it is an expensive habit!
