Hi, little bit of background...I'm 28 yr. old female, huge fear of cancer (grandmother died of Ovarian cancer), suffer from anxiety,panic attacks and tend to dwell on my aliments along with rushing off to every doctor. Anyway, a week ago a part of my very back upper right tooth broke while I was eating a apple. Went to my dentist and he filed my tooth down and put on a temporary crown. The swell has just went down and I can finally eat on that side. Yesterday I noticed a white patch (more of a white line) on that right side on my cheek that I can wipe off and underneath was a little red/pink so as I was looking with a flash light I also noticed in the very upper cheek (I think its next to that duct thing) where my upper tooth touches was also a tiny white spot that I could wipe off but it was bright red underneath. It almost looked like a tiny blood blister (like a few tiny bright red pen marks) but when I touched it there was no blood. There is no ulceration, no lumps or bumps, no pain, have no problems eating and swallowing. Does this sound like something from the act of taking X-ray, mold impression, filing my tooth because I remember when they took the x-ray the thing pitching my tongue and it was hurting my right cheek? Since I have a very huge fear of cancer and really do overreact, in your professional opinion should I be concerned (oral cancer)? Please avise and thank you for your time.
