I firmly believe that all the demographics of the practicing dentists, and the larger outfux of dentists than influx is definately true. And believe me, from what I'm hearing from the folks nearing the retirement age is that this stock market crash isn't deferring the pending retirement of alot of dentists.
As for how to find a good practice to line up for after dental school, first off you need to figure out where you'd like to practice and then start looking in that area. Talk to the state and local dental society in that area. Talk to alumni from whatever dental school that you goto. I definately though wouldn't rule out a residency though, it *can* be a far superior way to advance your dental treatment abilities than many 1st years in private practice. Also, keep your practice opportunites open, don't just assume that the 1st practice you enter after dental school will be THE PRACTICE for you. Especially in this day and age where there are and will continue to be moore folks retiring than graduating.
