My TN started with pain in my teeth. I would go to the dentist complaining of pain on the right side. Eventually, I had a root canal on every tooth on the right side of my mouth trying to battle the pain. It was useless. When that didn't work I was sent to the Endodontist, who after an unsuccessful root end resection, decided to send me to the neurologist. Kudos to the Endodontist that recognized the TN.
