I saw Dr. Chan for teeth scaling 1-2 times a year, I like him beacause the process was less painful in comparison to other procedures from other dentists. I think this has something to do with technique and surgical skills.
I went to Dr, Chan to do my braces, my front teeth did not look good. After checkup, he said it is because all my teeth is big, and so the front teeth were forced outward, he said that he had to first remove 2-3 teeth to make space for the front teeth, and then apply the braces. Took me almost 2 years, and I still have to wear braces time to time, but now it looks tidy, and I can smile with confidence.
