Is it one specific tooth? Or is it a few in a row? Because I recently developed new tooth pain but it's from clenching/grinding my teeth in my sleep. It's even caused me to have dibilitating migrains from time to time!
When I was little I used to yank out my baby teeth before they were loose. It didn't really hurt though. I would just sit there and wiggle them until they became loose and then pull them out, 4 or 5 at a time. AND THE BLOOD. SO MUCH BLOOD.
Use a car to run over your mouth and knock the tooth out!
Use mouthwash to see if the alcohol numbs the pain (rinse, don't drink, we're not talking that sorta "numb"). Then, get a flashlight, find a small mirror and have a look around in there. You can usually vaguely tell what the problem is and how serious it is just by looking. Can't help you find a dentist, I live in the UK and don't go to them. Hope it eases off.
