Dr Justin Saga of GPA Dental is my favourite dentist of all time. Very nice and friendly guy. He's very professional and experienced. He did my cleaning and it was really good and thorough. I didn't feel any pain.
My previous dentist that I saw, when she did the cleaning I could feel the pain so I didn't enjoy the process. I highly recommend go see Dr Saga. Saw his personal website and he used to work in NZ for over 10 years. You can contact him on his website for any questions. He replies them personally.
