OMG, I had a tooth break off at an old filling. I called the dentist, and they can't see me until next Thursday I hope it doesn't mean I'll need another root canal. They don't even do root canals at my dentist anymore. You have to go see a special endodontist for that. I already had to have one root canal and a crown this year, and that cost something like $1200, and that is with dental insurance My teeth are crap. I grind my teeth in my sleep, and I can't keep a nightguard on. Maybe I'll have to try a nightguard again after I get this tooth fixed.
