It's a Dentist Thing
Going to the dentist in itself is a stressful ordeal. Someone entering your mouth, poking around, and criticizing your flossing habits is something we all dread. On top of that, you're worried about your breath, you feel the saliva pooling in your throat, and you feel like you might choke.
Dentists don't make it any easier. While they stuff your mouth with cotton and pull at your cheeks, they ask you questions about your life. It's a tactic to make you focus on something other than the pain, but, oh dear, it's not working!
