I went in for an 8am appointment to get a wisdom tooth removed before work because the folks at the front desk told me I'd be okay to go straight into work afterward. That ended up being the case -- the procedure was very quick and simple, and left me with remarkably little pain. The dental assistant was fantastic -- supportive, friendly, super-knowledgeable and competent.
The main complaint I have is that the doctor herself who performed to procedure showed up almost an hour late to the appointment (she said "she had thought my appointment was at 9"). So I was sitting around for a long time waiting for a procedure that ended up taking just a few minutes. I thought that was pretty disrespectful of my time, especially given that it was a workday and I ended up having to cancel an appointment I had for that morning.
