i am so sorry of your tooth proved difficult. but you must know that every tooth is different and individual differs too. just imagine that someone received blow on his face and lost one tooth, but another person received same blow and the teeth remain as they were. again remember that one of the qualities of a good DR is making a good referal. for the fact that DR jung referred you to Dr chin alomst immediately has made him a good DR. even if both DRS received the same triaining, the two offices might not be equally equiped. again i am sorry for what happened but DR jung does not deserv that agrasive review.
