question: I have a bump on on my gum/under my nose. when it first arose i was in a lot of pain i went to the dentist and he said the x rays didn t show anything, he said there was nothing wrong with the tooth although i was in pain and couldn t bite. my front left tooth really sensitive because of the bump and the bump is really painful when touched. it also painful beside my nose... any idea on what it could be and what i should do about it (the bump is not visible but you can feel it it have gotten about 3 times the size in the last week
