Had a dental appointment this morning. It was brief and uncomfortable. The drilling wasn't a problem, as the dentist jabbed me about a dozen times with his numbing needles. However, he wedged my jaw open with something that looked like a small door-stopper, which was highly unpleasant. I do not have a flip-top head. Also fun was the delightful suction/spray-thingie constantly making me feel like I was being waterboarded.
"Waterboarded" is of course an exaggeration, but I didn't like it at all.
