Do I need a root canal? - traveling gum infection

I have a small infection of the gums. His lower gums before, not when the teeth and gums), but a little lower (around the roots. My cheek yesterday deaf because pushing the infection to a nerve. No color difference, however, without sensitivity to cold or heat. (Well, maybe a little heat and salt water as an injection) but not the actual damage to the teeth. I went to the hospital and began to take place two days before antibiotics. My dentist wants to do a root treatment. Yes, I had a fever, and the ground has not changed, worse or better. However, it seems kind of infection can be transmitted. Could it be, leave the room and the improvement? or when it will be worse?
