Nurse: Good morning. Dr Ellis’s office.
W: This is Mrs. Jackson. May I please speak with the doctor?
Nurse: The doctor is just busy with a patient. Would you hold on for a minute? Here is the doctor now, I’ll tell him you’re on the line.
M: Mrs. Jackson. Dr Ellis here. How’s that new bridge?
W: Not so good, doctor. That’s what I’m calling about. It just doesn’t seem to fit right.
M: Well, that’s to be expected during the first few days after it has been put in. Have you been leaving it in as I told you?
W: Well, it hurts so much, doctor, especially when I eat. I keep removing it afterwards, you know.
M: I understand, Mrs. Jackson. It hurts in the beginning, I know. But it would be better to leave it in except when you clean it, of course.
W: Well, I did at first, doctor, but my jaws hurt so much that I just couldn’t stand it any longer.
M: Well, maybe we can adjust it a little more.
W: Adjust it?
M: Yes, file it down here and there. When can you come in?
W: Oh, right away, doctor, if you don’t mind.
M: Let me see. I’ll check with my secretary. Maybe I can find time for you this morning.
W: Oh, I can wait until this afternoon if you’re too busy now.
M: Sorry Mrs. Jackson. I’d rather you came this morning if possible. This afternoon I’m teaching a class at the dental school. Just a minute. Mrs. Jackson, can you get here by 11:30? That will give us enough time before lunch to see what we can do.
W: Oh, yes, doctor. I can make it. Thank you. See you then.
