It's an odd experience. The Dentist is practically holding your head in his lap, drilling and probing and working in a very personal way inside your body. He can be toiling away in close proximity to you for twenty minutes at a time. You're swapping body heat, you can smell his cologne and he can smell yours...And then they stuff some blood-absorbent sponges in your mouth, tell you to bite down, and they breeze out of the room like it aint no thing.
Feels like you were abandoned, somehow.
