Doctor: Hi, Bonny. You haven't been here for over a year.

Bonny: Oh, that long? I thought it was only one month.

Doctor: You're still as naughty as you used to be. What seems to be the problem this time?

Bonny: My teeth seem to be sensitive to heat and cold. It'll bleed when I brush as well.

Doctor: Let's take a look.... Open your mouth wide, please....Does it hurt?

Bonny: No.

Doctor: Here?

Bonny: Ouch!

Doctor: It hurts?

Bonny: Of course it hurts. Do I have any decayed teeth?

Doctor: Yes, there are two of them. Does the gum ever ache or become sore to the touch?

Bonny: Yes, sometimes. Usually around the canine tooth.

Doctor: The teeth in that area seem to be sound. It might be a kind of gum disease. We may as well take an X-ray just to be sure.(Doctor adjusts the machine.)

Bonny: What about those two decayed teeth?

Doctor: The decay hasn't gone deep into the teeth yet. We can put in a gold filling.

Bonny:I think I'll do that next time. I'm in a hurry today.

Doctor: As you wish. Don't put it off too long, though. It'll get even worse.
