Dentist: "I need to warn you about what's coming next. It's going to feel like I'm thumping your skull with a hammer."
Me: "Well, because you are."
Dentist "Um, pretty much, yeah."
It's a wacky experience having a mallet (which looks something like a ball-peen hammer with nylon faces) and a ratchet wrench used on your skull in fairly rapid succession. Not surprisingly, I'm a little woozy.
