A couple days ago I noticed my way upper gum felt sore and yesterday I looked in the mirror and noticed there was a white looking pimple far from my teeth. I read online that if it is close to your teeth that it is a dead tooth. But the pimple is far from a tooth and closer to where my cheak and gum meet. Im not sure if it has anything to do with not washing my hands well and touching my mouth, which I sometimes do or it could be from something else. I did have a dentist appointment a couple months ago to have a cleaning and a tooth filling fixed but that tooth was way in the back far from where the pimple is at right now. Not sure if I should be concerned...Thanks!
