It would be a last-ditch resort, but if it's truly debilitating, I understand the ER will pull teeth. The downside is a huge bill that you probably can't pay, but unlike private practitioners the ER is used to that. For us poor folk, it's as close as we can come to universal healthcare.
Myself; I am plagued with many dental issues and get it all done in Mexico where it's extremely affordable and I get better care than in the U.S. Being on the northern end of the country I wonder if a trip to Canada would be worth it? I haven't heard how much (if at all) less their dentistry is than ours.
Finally, if it's not a dire emergency but there's a pain issue, one part clove oil mixed with one part olive oil. Just a drop or two on the affected area is a great natural painkiller.
Good luck. I totally feel ya when it comes to dental woes!
