Dr. Pirok provided very unprofessional service and was more concerned about making money than my treatment. In describing the dental procedures I would need, he said that "mommy and daddy can pay for it." He also gave me a filling that caused tremendous pain afterwards and then wanted to instantly give me a root canal on the same tooth at my follow-up. I chose to see an endodontist instead, who, following evaluation, decided that I did not need a root canal. I never had another problem with this tooth. I suspect that Dr. Pirok intentionally set up the pain as an excuse to perform the root canal. I felt that I could not trust what he said, and he was very disrespectful toward me. I know 3 other people who have had similarly negative experiences in this office, including making comments about getting parents to pay for things, misdiagnosis of nerve problems, and other issues. I think that Dr. Pirok wants to take advantage of the students at the University of Pennsylvania for his own financial aggrandizement. I would never return to this dentist, and I encourage everyone to seek treatment elsewhere.
