Flare-up after canal instrumentation is not uncommon. Systemic administration of appropriate antibiotics tends to clear up infection in 72 hours.
Hi. After nearly a dozen of the darned things, I agree that you should be getting better and better, not back and forth. Just show up in his office with your swollen face and tell him that you feel like he's blowing off your concern and that you want a guarantee that you're not harboring an infection. Ask him how he, not you, can solve the problem, and if you're not 100% satisfied with his solution, tell him so. If he can't attempt to solve the pain issue, raise the pen and paper that you've been holding in your hand, and tell him you just want to make sure that you have his name and address spelled correctly, then smile and say that you're posting your experience with Med Help's dental community messages. If he still can't solve the problem, walk out and let him stew in his own pew! Go to the Dental Association, register a complaint, and ask for a referral for someone to help you. If your town is too small for a dental association, just show up at your dr's office, explain the situation, and ask them to get help for you. You need to act on this without delay. It's much harder for them to try to avoid helping you when you're standing in their office.
