Randolph Yip replaced my ortho's permanent retainer with his own and then couldn't maintain it. Against my perio's recommendations, Yip said I should get braces, dentures, or implants. He joked about my teeth, saying that he wished he could sell my tartar. He said I needed to bring in my toothbrush because I didn't know how to brush my teeth. When leaving his office, he said that we would have to subpoena him for our records.
