Dentist part 2

Monday the dentist fixed my right lower back molar, today he fixed my left lower back molar. The weird part was after he shot the left side of my face up with noavacane he was taping on my right molar and said that it seemed a little high. So the he proceeded to use a drill to file down the filling he put in my right molar, you know the side of my mouth without novicane. I didn't find it funny.
