 A:    Hey, Gary, great to see you again. Please have a
       seat. So tell me, what seems to be the problem?

 B:    Thanks,  doc. I’ve got a really bad toothache! I
       can’t eat anything, and look, my face is all swollen¹.
       I think it might be my wisdom tooth.

 A:    Well, let’s have a look. Open wide. Hmm...this
       doesn’t look good. Well, it looks like you have a
       cavity² and your crown is loose.  We’ll need to put
       in a filling before it gets any worse, and the crown
       probably needs to be refitted. I’m going to order
       some x-rays.

 B:    Is it gonna hurt?

 A:    No, not at all! Just lay back and relax.

 A:    Ok, spit.
