If you are working fewer hours, then you have to take on a smaller patient load. There is no reason why you can't work your schedule around Monday, Wednesday, and Friday. Very rarely are you going to send something out to the lab on Monday that would enable you to insert that crown on Tuesday. You have a week turnaround before you can do the inserts, so flex time should not make a difference as far as delivery of care, as long as you do not overbook yourself. If you are only going to be part time, you are not flooding the market as much.
Patients can at least see somebody.
I work for a cardiology group with 10 physicians. I think that is what is going to happen with dentistry. You are not going to have just this one person working out of their office all the time, you are going to have more variety. The public has to realize they are not going to be seeing the same individual all the time. In dentistry, at one time, when you went in you would see Dr. So and So, and he would be your provider all the way down.
