I had my first ever root canal last week, and although I was terrified, I got through it just fine (with a little help from lorazepam, and of course my dentist is awesome!) A coue days later, u noticed the pain getting worse, and as of yesterday morning, my face has seemed to develop it's own heartbeat in that side. I called the dentist back, and she gave me a prescription for antibiotics, she said it sounded infected, and not to worry because it's not uncommon. In the meantime, with the power of the Internet, I have now convinced myself that I'll have to have some sort of oral surgery for certain. J was wondering if anyone has suffered from this before, and what may e to expect? My second RCT appointment (same tooth) isn't for another week and a half.
