I had the fastest appointments of my life at Dr. Carpe's office. She never found a cavity, but she spent about 5 mins on my teeth. I felt that she did a superficial job. When I switched dentists (due to a health insurance change), I was all of a sudden diagnosed with 4 cavities within a year (after years of having none). I don't think I can know with completely certainty, but I wonder whether it's attributable to her fast cleanings. Also, I can't comment on how expensive she is; my insurance paid.
