What's wrong with my teeth?

Had a bad toothache situation for awhile now. It was barely noticeable pain for about a month, but now it’s spread to all the 4 front teeth on my upper and lower jaw, plus the left canines, over the past weekish. 20% benzocaine Orajel not helping. Advil and Tylenol do nothing. Using Celebrex now, but it’s only barely keeping the edge off. Swishing whiskey helps I’ll never need chaser again. The pain cycles from nonexistent to debilitating every half hour, as of yesterday.

I can’t identify any triggers for the pain except hot and cool, which I’ve already been avoiding for weeks now. I have spoken with both my dentist and pain specialist/neuro about this. I saw the pain guy today; will see dentist Monday. From both I get “Huh. That’s weird.” Weird because although a single tooth hurting can radiate to the surrounding ones, the fact that it’s happening on both my upper and lower teeth is unusual, and that it’s spread this far. My dentist said I’m describing the feeling people have from getting their teeth knocked out. The words “nerve damage” have been tossed around.

WTF? Have any of you heard of something like this? Everything I look up on toothaches don’t really describe the things I’m experiencing.

And of course, I welcome your toothache remedies.
