Since the human body differs so dramatically from one person to the next, and since the entire fields of prosthodontics and restorative dentistry are ALL about creativity, I would say it's one of the most creative professions there is!
Try to shadow a dentist that does a lot of pros...I think within 5 minutes you'll be able to answer your own question.
You can also get creative with your practice. I don't mean the physical decor, but rather how you set up your business plan, what type of services you offer, what types of patients you see, and the ways in which you give back to the community. I shadowed one dentist who took his whole family to Tonga and established a free dental clinic, and another who teaches elementary school kids who to brush and floss properly.
In dentistry, you're only limited by your own creativity.
