White spot in mouth

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.

Certainly not being able to see your mouth it is impossible to diagnosis what these white spots are. I would venture to say that this is NOT oral cancer. But this does not preclude that you should see an oral surgeon for your own peace of mind.

If you could wipe the area off it may have just been some debris left behind from the procedure and your mouth if bound to be inflamed after a filling and from you poking at it. (Not trying to be mean here I am also a hypochondraic)

You said you are 28 and I think the odds of oral cancer are very low and I doubt you are a heavy smoker or drinker, or use smokless tobacco.

Just call your dentist and tell him what you see and he will know if you need to follow up.
