High EGT-You certainly have my sympathy. I'm going through the same thing, bottom tooth on the lower right started bothering me about two weeks ago. Of course, this was a Friday evening and I had to wait until the next Tuesday for a dentist appointment to get a prescription for the anitbiotic and a referral to another dentist for an extraction, which won't be until the 10th.
The tooth is capped but decayed in from the gumline. I've suffered with acid reflux for years-it was only recently that I was advised that acid reflux is a major contributor to tooth decay-and explains why I have so many caps and root canals in the back of my mouth. I thought I was cursed with bad genes or something. Wish my doctor (or dentist) had thought to let me know about the complications years ago.
Anyhow, I'm actually looking forward to Tuesday so I can have this darn tooth pulled.
Good luck!
PS-Love your avatar-The Day The Earth Stood Still was the first "scary" movie my parents let me stay up to watch in the early 1960's-way back before the advent of cable TV and the SciFi Channel.
