W:Doctor,I'd like to have a check up on my teeth.
M:Hi,Bonnie.You haven't been here for over a year.
W:Oh that long.I thought it was only a couple of months.
M:You are still as naughty as you used to be.What seems to be the problem this time?
W:My teeth seem to be sensitive to heat and cold for the past few days.
M:Open your mouth wide,please.Does it hurt?
W:No.
M:Here.
W:Pouch.
M:It hurts.
W:Of course,it hurts.Do I have any bad teeth?
M:Yes,there are two of them.The decay hasn't gone deep into the teeth yet.We can put in a gold filling.
W:I think I'll do that next time.I'm in a hurry today.
M:As you wish.Don't put it off too long though.It'll get even worse.
