I've been going there for years and they've only ever told me about two cavities that they were "watching." I went to get one filled last week and they ended up drilling three teeth without my permission and then told me about 3 more cavities. They then tried to cover up what they did by saying they knew all along. Dr. Lau told me something different from his main assistant. He said my teeth had to be filled and she said I could go 20 years without filling them. It was a horrible experience and I now am feeling severe pain in my jaw and it hurts to open it.
