Yes, I believe my trigeminal nerve disorder started after my first and only root canal. I've had RSD for 12 years but not diagnosed for several years and had no idea about precautions before dental work. About 7-8 years into having RSD, my neurologist diagnosed me with TN. Now before any dental work, I take antibiocs and the gas mask. It scares me to death. any dental work, as you can get rsd inside your mouth. My dentist and dental hygenist have both read info. on RSD. I wish you all well, Loretta
