A good friend of mine recommended Dr Chung when one of my tooth broke into half. I completely gave up on it and I went to see him to extract the tooth as 3 other doctors had said that is the only solution. Dr Chung worked more than 1.5 hrs to fix my tooth without any pain (even the injection was completely painless) and I was watching a movie in the meantime. He is amazing and highly recommend to anybody for any needs.
