So for the past week or so, my upper right gums have been sore and raw, painfulwhenever I brush my teeth. This is the same area in my gums where I was cut open a while ago in order to remove a (harmless!) cyst from my right sinus, and which was numb for several months afterwards. I've looked, and can't really spot a visible difference, though it might look a little red, and there may or may not be a small circular bump. I've been having recurring nightmares of my teeth falling out since, well, forever, so I've been brushing and using mouthwash a lot lately, but there isn't any pain on the other side, or on the lower gums. I'm kind of a hypochondriac, and I'm afraid this might be oral cancer or something (which it isn't, I know!); it's just that, while I've occasionally had sore gums before, it's never lasted more than a day or two. So what should I do? I'm only 20, and I don't smoke or drink, so I shouldn't be getting any serious health problems yet, right? Should I get this checked out, or do I not need to worry?
