Oh man, i use to have tons of cavities when i was a kid. I hated that procedure of putting in fillings. It's slightly painful without numbing, but nothing i liked sitting through. Just that sitting in the chair, the procedure from my youth seemed like it took soo long, like 10 minutes or something. The noise the instrument makes is unsettling, the length of time it took was unsettling, what they're actually doing with you tooth is unsettling, the mild mannered pain gets irritating, and the fact that it made my head vibrate like a black and decker sander i didn't really like.
Whatever happens in my life...when i was 5.
