Dr. Chung and his staff were very difficult to understand. (very broken English) The waiting area was small, old and dirty. I waited about 20 min. to get in. I was there for a severe toothache. He did an x-ray and said he could not see anything wrong. He sent me home with no further advice. I went to a different dentist for a 2nd opinion. They also did an x-ray, and said I definitely had root inflammation and needed a root canal. After the root canal, I had no more pain. I suffered in pain many days because Dr. Chung did not properly diagnose me in the first place.
