Tina visits her dentist, Dr. Li, for a checkup. After taking X-rays, Dr. Li tells Tina she 'II need to replace a.filling.
Dr. Li: Have your teeth been giving you any trouble since your last checkup?
Tina: The back molar on the lower left has been killing me!
Dr. Li: Let's see here. It looks like the filling is loose.
Tina: Isn't that the same one you replaced last year?
Dr. Li: I'll need to check. I can't remember off the top of my head.
Tina: Also, one of my top right teeth is a little sensitive.
Dr. Li: Which one?
Tina: This one.
Dr. Li: Okay, I'll take a look. It looks a little discolored. We'll get a set of X-rays today to get to the bottom of it.
Tina: X-rays? Will that be an out-of-pocket expense?
Dr. Li: No, you're due for a set. It'll be covered by your insurance.
(Dr. Li takes the X-rays.)
Dr. Li: (looking at X-rays): Let me give these a once over ... It looks like we can hold off on that top tooth.
Tina: It does hurt, but maybe it's just a figment of my imagination!
Dr. Li: Call us if it keeps acting up. In the meantime, we'll need to replace that filling. Please make an appointment for that.
