B:Well,let me have a look. Will you sit down in this chair and open your mouth wide?

A:I think one of the back ones at the top is giving me the most trouble.

B:Yes.This big one is badly decayed. I'm afraid it must be taken out.

A:Oh,I hate habing teeth pulled out.Will it hurt?

B:No need to worry. You won't feel anything at all. I'll give you an injection to stop the pain. Just wash your mouth out with this water, will you?

A:Will it take long?

B:No,it'll be over soon. Nurse, get some X-rays of our patient's molars. Then we'll start. Open your mouth wide. Don't be so nervous. Now open wider... now steay, that's over...

A:Is it out?

B:Not yet, but it soon will be. Now open again please...It's out! Look!

A:Well,really! That was wonderful!I felt no pain at all.Thank you,doctor.
