I went to Dr. Mai to get a filling, and I had pain. even though I told her which teeth had the pain she was saying my other tooth next to the one I had pain is causing the problem. then she gave me amoxilin, I went after I finished the amoxilin, and then looked at my teeth and found a cavity and cleaned it and put filling. 2 weeks later I started to have pain again and she looked at the teeth again found another cavity on the same teeth and cleaned that spot and put a filling again. but I still had the pain. so I told her could you just remove all the old filling and clean the teeth then make a new filling from scratch and she didn't do it. she told me to go to an endocrinologist to get it evaluated thinking I might need a root canal. i didn't want to lose my teeth by getting a root canal and hoped it would heal. 2 weeks passed since then, I don't have pain, it hurts if I bite on it and now my teeth is swollen. and I am looking for a new doctor. 1- she didn't show interest when I told her I had pain, she wasn't interested in figuring out what was the problem. 2- she charged me twice for the same teeth. she could have found both cavities in 1 visit and fix them both, but it took her 3 times to see these cavities. not a good dr.
