Dr dalton's root canal resulted in me having Trigeminal Neuralgia (suicide disease) by damaging my Trigeminal nerve. Years of dibilating pain and 2 gamma knife surgeries. I went to him the day after the root canal complaining of the pain and he said it was normal. I continued to complain as at that point I didn't know what it was. He took no responsibility in trying to help me and at one point became irate that I was complaining. I eventually ended up in the emergency room. That's how I discovered what was really wrong.
