Bonny: Doctor, I'd like to have a check-up on my teeth.


    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.
