Billing after dental care PLEASE HELP

I have a very bad tooth at the moment and I'm in excruciating pain. I don't think I can really deal with this pain much longer. I am freshly out of college no job and literally no money. Finding a job hasn't been easy. I need to know if there is any possible way I can go into a dentist and tell them I just want a tooth pulled and that I have absolutely no way of paying for anything at the moment. But I will be able to pay as soon as I get a job. I just want the tooth pulled out I don't want anything else done to it and I want it done asap! HELP PLEASE I don't know what to do. I really can't handle the pain anymore. I can't even sleep it's so freaking bad.
