Me: Okay. It's just a cavity. Nothing to be worried about in spite of the fact that you've never needed freezing while getting a cavity filled before.
Uber-cheerful dentist: Hey there! Now, I know you're nervous, so let me explain everything in great detail as we go along, possibly with the aid of diagrams and an interpretive dance!
Me: Just a cavity. Nothing to worry about. Just a cavity. Nothing to worry about. Just a long, pointy nee- argh! Just a cavity. Just a cavity. Just a cavity.
Heart: Badumbadumba dum ba dum ba dum... ba... dum... Whew. I think I'm okay now.
Long pointy needle: Hi there! Allow me to insert myself into the muscles of your jaw!
Uber-cheerful dentist: Look, we're putting a clamp on your tooth! Isn't that neat?
Uber-cheerful dentist: *pokes around with dental tool not unlike cattle-prod* Wow, this goes down pretty deep! Just let me chip away at this enamel here...
Uber-cheerful dentist: ... and scrape around in there with this- here, do you want to take this mirror, to see what we're doing?
Uber-cheerful dentist: Now, let's go with the drill again...
Uber-cheerful dentist: You could probably do with a bit more Novocaine, couldn't you. Oh, well, too late now.
Uber-cheerful dentist: There we go, all done! That wasn't so bad, was it?
Me: My jaw muscles ache.
Uber-cheerful dentist: Yep, they'll do that.
