[speaker001:] I have a terrible toothache.
[speaker002:] Which tooth is it?
[speaker001:] [Pointing] This one here.
[speaker002:] Ah, yes. There's big cavity.
[speaker001:] Can you fill it?
[speaker002:] I'm afraid not. The tooth is too far gone. It'll have to be taken out.
[speaker001:] Then I might as well have it out now.
[speaker002:] You'd better wait. The gums are swollen. Take the medicine I prescribe and come back in three days.
