My nightmare began in a general dentist's chair following a root canal procedure. A Texas dentist injected some "medicine" into my tooth canal and severe pain and infection immediately followed. I lost my voice, and my news anchoring job. The pain almost drove me to take my life. I was turned away from many doctors and the emergency room. Finally after seeing 25-30 specialists I was diagnosed with possible TN or more likely, atypical facial pain. A story on Prime Time Live in the early 90s told of a bunch of Texas dentists that performed the "Sargenti Method"--a seminar procedure where they injected a substance, I believe it was formaldehyde, into the canal. Years before that, though, I had already had three upper teeth on my right side root canalled, roots clipped and finally those teeth pulled. My endodontist told me when he clipped the roots he saw "a lot of granulated tissue”, whatever that means. I assume horrific damage. It's been 15 years and I'm now on Neurontin and one .05 xanax a day. I just came off a 10-day attack and my face is still throbbing. The pain is right above where the problem tooth was. The other teeth didn't need to be pulled; none of them did. I also wore braces in my 30s which did little. I had four sinus surgeries, including a maxilla antrostomy, something like that, and a septaplasty (sic). Has anyone ever heard of the Sargenti Method causing this syndrome, or had dental procedures linked to their TN. Surgery is not an option for me at this time. In my case, onset was the same day as the original root canal, which, as I've said, was not a typical procedure where the root is removed. I found years ago that no dentist would implicate another in his dental brotherhood, and to this day, I have no resolution. I never saw my MRI, but in 1989 my otorhinolaryncologist told me he thought I might have had damage done to my sinus wall. Please write back if you have any information on this.
