Dr. Tin made 2 big mistakes and did not appologized. She gave me mercury fillings instead of the porcelain ones I wanted and told her so the visit before. I told her i didn like the silver color on my teeth so when i went the next week I had my filling done and then I realized they were not the white ones. Also that same day , my tooth was chipped by her and she later told me I had done it. How can I have done it when I realized my tooth was chipped right after I left her and before I have had anything to eat. Also the person that did the cleaning was very rough and it was very painful. Never had I've been concern with a dentist visit before but now I am because oft the pain I experience at her office. Its been 3 years and I haven t had my others fillings she was supposed to have done because of the fear of pain.
