I always imagine that people working in dentistry end up getting incredibly jaded. There's only so much neglect of basic personal care that anyone can face. Over and over again. And people don't listen to the recommendations because it is all going to be fixed by the dentist.

The younger dental professionals I have come across tend to have real passion and make me go "oh wow, they are really into this and inspiring!". Which seems to wear off over time. Maybe it's just me projecting from what it's like to work with computers because it certainly feels familiar.
