【听英文对话做选择】牙齿护理

原文：

Patient: Hi. Dr. Hyde?

Dentist: So, what's seems to be the problem today?

 

Patient: Well, I just came in for a check up and a dental cleaning.

 

Dentist: Hum. Open up. Let's take a look . . .

 

Patient: Okay. Uh . . .

 

Dentist: Hummmm. [Humm? Uh?] Wow! I've never seen one like THIS before. Let me try this.

 

Patient: Uhhh . . . Ouhhhh [Man screaming in pain . . .]

 

Dentist: Well, besides a lot of plaque¹ buildup, there is a major cavity in one of your wisdom teeth. [I feel that.] Hasn't this given you any trouble?

 

Patient: Well, the tooth has been bothering me, and it sometimes hurts when I drink something cold. Does it look that bad?

 

Dentist: Well, we're going to remove the decay, and then we'll either put a filling in, or if the decay is extensive, we can't repair it, we might have to put a crown on your tooth. Or as a last resort, we may have to extract the tooth.

 

Patient: Uh, well, that sounds painful!

 

Dentist: Don't worry. I've done this . . . once before. [Huh?] Nah, just relax.

 

Patient: Wait! Aren't you suppose to give me something to dull the pain?

 

Dentist: Uh, chicken. Oh yeah. I almost forgot. We can either use a local anesthetic² or nitrous oxide³ . . . laughing gas. . . to minimize the discomfort⁴ you might feel. Or you can just grin and bear it.

 

Patient: Nah, Nah, nah! Put me under! [I thought so.] I can't stand pain, and I'd rather not be aware of what's going on. And, if I need a filling, can I get one that looks like my other teeth?

 

Dentist: If we can save the tooth with a filling, I recommend a high-strength silver alloy⁵ filling instead of a porcelain⁶ one. It'll probably last longer.

 

Patient: Okay, well whatever. Let's get it over with.

 

Dentist: Okay, pleasant dreams. Drill please.
