I've never intentionally bit a dentist, but I did accidentally do it (actually it was a hygienist) because I could feel a sneeze coming on and tried to get her hands out of my mouth by garbling words around her hands. When that didn't work I tried to physically push her hands away only to be lectured that she was almost done and it would only be another 15 minut..SNEEZE!! I was then lectured that I should've told her to move her hands. Like I DID!!!! I was pushing with all my strength and you resisted me because you thought I was a petulant child. She also embedded a hook so deep in my gums that it took a week before I couldn't see the hole and then lectured me about the importance of flossing because apparently it only bled cause I didn't floss. Still not sure how I was supposed to floss under my tongue though.
