Dr. Shoemaker, in my opinion, is not stable. I was referred to him by my dentist to have a piece of metal removed from inside my molar that was broken off during a root canal. Payment arrangements were made in advance for him to be paid by my dentist. When the work was almost completed, I asked Dr. Shoemaker if he was able to get all of the metal and he became very irate. I did not understand what happened, he just snapped. He yelled at me, told me he was the expert, and told me that I was not going to come in his office and "mess" with him. He told me I was disrespectful and even ungrateful, because my dentist had not paid him for the work he had done. I told him I had nothing to do with payment arrangements made between him and my dentist. He yelled at me again "there you go with that disrespectful mouth." I had my young niece with me and she was terribly frightened. I told him to seal my tooth and let me out of his office. I was actually frightened he was going to do something to hurt me and my niece was so scared, I had to get her out of there. He berated me the entire time he sealed my tooth. I'm complaining to the TN State Board and I do not recommend this dentist to anyone. He is narcissistic, cruel, and unstable.
