I told the dentist that I was a bad patient because I have a low tolerance for pain--he took out 3 fragments of teeth-- my face was inflamed from the fragments --Dr.Dong and his friendly staff really took care of me--made me comfortable and I could tell thye knew what they were doing---the operation went so well that I was able to return to work the same day with no complications and did not need any pain medication. I was going to be visiting another dentist office but have opted to go to Dr Dong.
