I was scheduled to get four of my wisdom teeth removed and 1 tooth that had cavity decay. In total, I received approximately 12 shots. During the process of removing the tooth with the cavity it was like a nightmare from hell. I stated to Dr O'Brien that I still felt pain in the inside of my mouth. He gave me another shot but I was in pain the entire time. Once that tooth was removed I raised my hands up, removed the gas and told him that I was done and didn't won't the four wisdom teeth removed. He put his instruments down, stormed out of the room while mumbling "she is so disrespectful!" As if he was throwing a temper tantrum. His dental assistant stayed in and she was very humble. During checkout she asked the receptionist if she could speak to Dr. O'Brien. The receptionist proceeded to knock on his office door. With aggression, we heard him saying, "Where is she!" He swings open the door and says "Yes ma'am!" My mom told him the way he stormed off leaving his patient laying there was very unprofessional and she doesn't have disrespectful children (in reference to him calling me disrespectful). She also told him that I have the right to turn down any additional service if I'm uncomfortable and in pain. Dr O'Brien says, "I try to help everyone one... YOU PEOPLE...I try to help you out with the free service..." My Mom stopped him and said "You People?" He then says, "I'm not going to do the race thing with you." He obviously made a reference to my race and/or my financial status by saying "you people" and "I try to help you out with free services." After making those statements he told us to "leave his premises and never back." My mother said "With pleasure and we won't be coming back." We walked out the door and we heard him locking his office entrance door behind us. He was very nice and pleasant in the beginning but once I refused further services from him it's as if his true colors were revealed. I am very offended and wouldn't recommend anyone to him.
