I would like to estimate Dr. Au from two perspective. Admittedly, he is a nice guy, warm-heated, and provided a bunch of good suggestions for my teeth treatment--- I'm a shamed of my bad teeth. While honestly, I couldn't give him credit for his treatment on me. I did the filing treatment for my two teeth at Dr. Au's office. Honestly, both of them are not complicate dentistry job, but I was always feeling painful after the treatment, and it has been 6 months since I came back from his office...
So I do believe only good attitude is absolutely not enough for a dental doctor, just like Dr. Au.
