I shadowed a dentist last week........it was actually pretty chill. I just stood around and observed him doing his work, and we talked to each other frequently. He showed me his office, some restorative cases he had done, explained a little bit about reading X-Rays, and let me ask questions about anything I wanted to. Honestly, I felt a little bit intimidated walking in to shadow because I'm a high school senior, but it was a great experience. Just relax and be cool. Ask lots of questions, but don't cross the line(for example, saying "why is there blood everywhere?" when he is operating on the patient). Also, make sure you dress business casual. I wore gray dress pants, a white button down shirt with the sleeves rolled up(acceptable for spring/summer), a tie with a clip, and brown dress shoes. The only thing I would have done different during the shadowing is take notes! I forgot to do this, but I will be sure to next time. Hope this helps!
