Dr. Schwartz did a root canal. Still was experiencing pain and swelling after the work was done. Got it checked by Dr. Schwartz, and I asked if it was possible he missed a fourth canal, and he said no, everything was fine. He ground down my tooth and said that would take care of it. I went to see another endodontist, who said I needed to redo the root canal, he found a 4th canal. My mouth was infected and swollen. After the 2nd root canal by the other endodontist was done the swelling began to subside and my mouth is now healing. I got a refund from Dr. Schwartz for the entire procedure and will NEVER go to see him again. Not only is his work as an endodontist sloppy but his attitude was defensive and harsh.
