W: Hello, Mr. Wang. How are you doing?
M: Mm... I’m well, but I have come here for something.
W: Oh, really. Have you been having any problems?
M: (16) I’ve been having a toothache.
W: Can you describe the pain for me?
M: (17) It’s quite a dull pain, and my face is swollen.
W: Is the tooth sensitive to hot or cold?
M: Yes, it hurts when I drink anything hot.
W: Is the tooth tender when you bite on it?
M: Yes, it is.
W: Does it hurt just during the day or at night as well?
M: It hurts all the time...
W: (18) Your tooth is infected, and there might be an abscess under it. (19) I will give you an antibiotic to reduce the infection. If the swelling doesn’ t go down, I’ m afraid I will have to lance it or perhaps root canal. (20) I want you to return in a week, and I will put a gold post in the tooth before I crown it for you, assuming the root canal treatment is successful. We usually have to let the tooth settle for 3 to 6 months before crowning.
