Dr. Butler had a visiting assistant working with him on the day of my last appointment. Long story short, I kept telling them that the assistant was hurting me and I was told I was imagining it, that I had been numbed and could not feel it. I also had told him of pain I was having and he immediately opened my mouth and began to "sand" my back teeth. I tried to stop him and tell him no that wasn't where the pain was. He chose not to listen and continued to do what he wanted. He didn't even use the blue film and ask me to grind my teeth to see if that was truly the cause. I finally got a chance to show him where the pain was coming from and he told me that the brown spot was a stain. I (without training) know it is not just a stain!! The doctor's hands were swollen larger than I had ever seen them before and he stretched my mouth more than necessary. I was obviously crying throughout all of this, but was afraid to have him stop in the middle of everything and be in worse pain. He and the assistant told me I was being overly sensitive and had no reason to cry. I have NEVER been made to feel physical pain let alone cry at a dentist's office before. Dr. Butler is a wiz at marketing himself, but don't believe all the hype!
