Re: root canal tooth reinfected
I really do not have any advice, but am going through the same thing, except that my root canal was done 12 years ago and I am facing my first apiectomy next month. It sounds like we have the exact same symptoms and everything. One thing my regular dentist recently tried was putting me on penicillin. It has flared up a few times in the past and whenver I took the antibiotics it would get better, sometimes not flaring up for more than a year, however this time it didn't work. That might be an option to try first. Its also the first thing my new endodontist asked when I went last week. It might be worth a try since its a lot easier and a lot cheaper!
Good luck to you!
