Great thanks, guys, for your responses. Some good suggestions in there. I did call my dentist and left a message (He must be on vacation, getting an early start on the Fourth of July weekend 😀 ) about shadowing him in July. Last visit, he was really excited that I was applying to dental school, so I think he'd be willing to show me the ropes and whatnot.
My fear, however, is that I will be "in the way." I know if someone followed me around the chemistry lab, and I had to explain what I was doing and why I was doing it, I would be far less productive than I am now. Did you ever feel like you were in the way during your shadowing experiences?
