I can’t eat or drink anything.

I thought I had been keeping up well with my teeth but yesterday pain started shooting through my upper and lower left molars and they have not stopped hurting. At first I tried drinking some water and it shot through my tooth for about 5 minutes, I later tried to drink room temperature water and had the same effect bad enough for me to start hitting the table out of pain, I’ve tried drinking every temp of water, eating actual food, eating snacks, but it hurts so bad to try and consume anything at all. I have no family, no insurance, and no way of paying for or receiving treatment because I have no documents and can’t request them until I’m a legal adult. Is there anything I can possibly do? I’ve tried oragel as a temporary solution but I still can’t eat or drink anything.
