Dr teng is a true professional at what he does, he removed all four of my wisdom teeth all at once, the procedure went very fast and smoothly, i had no pain during or after the extraction, and i was very surprised that there was no swelling at all!! just fyi dr teng seems to always have conversations with the assistant while working on the patient, i think one of the reasons he chats is to help calm down the nerve of a patient and to distract a patient from worrying about their teeth
