Dr. Harris is great but doesn't take my insurance anymore. Now I use Dr. Phil Davis (south 31st street near Taylor's Valley). He and his staff are really great and the office is beautiful.
Curtis Fort near the Santa Fe Credit Union. He's really good, gentle, and really honest.
I've found the main advantage of him over other dentists is he does ALL activity, including cleanings, whereas most others leave that work to dental hygenists.
