dentists, ugh

Eight months ago, I went to the dentist to get a root canal and a cap. Fast forward to today. I've been having problems with said tooth for a while now and finally decided to do something about it. I went in to the dentist today and he tells me that my root in said tooth is starting to get an infection. So, they slap the gas on, shoot me up and fix my tooth. They drilled a hole in my cap, took out my roots (I think. I was a little out of it right about this point. I do remember the dentist calling me a light weight.), and gave me oxygen. My jaw is really sore right now. Add on top of that a migraine I had last night, and I've had a great couple of days. On a brighter note, the dentist did not charge us for anything!
