I went to this dentist to have upper and lower dentures made and in order to have this done, I had to have three front lower teeth extracted. Dr. Bui administered 3 novacaine shots and waited until the shots took affect. Mean while the doctor left to treat another patient. By the time he returned (20 minutes), the novacaine had started to wear off, I informed the doctor but without giving additional shots, proceeded to extract my three teeth. It was the most painful experience I have had with a dentist. After almost three weeks, my mouth was swollen and he did not provide pain meds. He is a butcher. (and maybe a sadist?) Do not go to him unless you enjoy pain!
