I highly doubt that Atlanta is over saturated with dentists. I just moved from there in July and at that time all the dentist I knew said I could open a practice and do very well on any corner in the city. I also know that every dentist I called in my county was booked for a year and a half when I tried to switch dentist and get in for a cleaning. I don't see that having changed drastically in the past year. The whole state of Georgia save Augusta is dentally underserved. I plan on going back there when I finish school. Atlanta is a great city and a practice in Buckhead coupld pull in a ton of money easily especially if you are interested in doing cosmetic work.
