Suggest Treatment For Severe Toothache Due To Infection

i have had a severe toothache for about 3 weeks. I know i have a severe infection because the pain is so intense. The problem is i did not have the time to change my dental insurance so im stuck with a plan that most hospitald wont take. Dental care in New York are very expensive and i really dont want to pwe anybody for years to come. But this pain is so severe at times that i think my hea will explodde. I get the worst headaches and i cannot eat anything without fear that i will cause my mouth to hurt. While at work i take at least 7 or eight ibuprofen for the pain. And at home about the same or more so that i can sleep. My ear hurts all the time, and sometimes feels clogged. My face burns sometimes, tingles and even feels sore and numb when the pain is at its worst. For the last two or three days not even an ibuprofen seems to be helping. After about 10 minutes the pain returns. It builds up like a contraction during childbirth and then at it its worse when i feel to faint it subsides. I cant take this anymore and now its the weekend. I need to go to an emergency dentist to get some teeth puled, if not tonight then definetly Saturday morning. What can i do to help the pain, will an emergency dentist in a local hospital see me even if they dont take my coverage? Please help feels as if i will die.
