i have a white cut on my gums about 1/4 long, it started off as a white bump(blister) and opened to a cut. it hurts very badly to eat anything or to even lay on that side of my face. i think i cut it with a tooth brush. About a week ago i was brushing my teeth and i jabbed the side of my gum with my tooth brush really hard but the blister/cut didnt form until 4 days after i jabbed it and it didnt bleed. (just a suggestion of how the cut formed) BUT I CANT EAT ANYTHING!!!!! CAN ANYBODY HELP ME ?!?! tell me if it is something else or how can i heal this!??!
