Dr. Quinn Su, on Van Ness Blvd and Pacific Street in San Francisco, is an excellent excellent dentist. I know this because I'm a pediatric dentist myself and I know her work is really good (she's my own dentist). 1-2 days a week, she works with children at the practice that I work at, so she is very gentle and can work well with people that are nervous.
You can reach her at ###-###-####.
Good luck!
