Dr. Kim does good work, but I have to say it is sometimes at the cost of the patient's comfort. He is extremely quick, so quick that he sometimes misses things. For example, I had 9 crowns done at once recently, and he just whipped through them. Not only was I in agony for two weeks following, but I was pulling some sort of string that he used for the impressions out of my gums for the next ten days! Very painful. I don't know if he is just trying to make the most money in a given time or what, but it's clear he has never been in "the chair" himself, or he would be a lot gentler. He will not prescribe pain medication either, so if you have sensitive teeth, I would stay away!
