Oh, my gosh. I have had a root canal before where I almost fainted from the pain. Dr. Aimar did three levels of anesthesia and took plenty of time to make sure I was numb enough. His communication was excellent! At first the numbness didn't go as far as he'd wanted so he did another shot and waited again. I think it was a total of 30 minutes from the beginning of anesthesia to when he was ready to drill. I did not feel a thing! He has a beautiful view from his window.
