听力原文：M: Hi! Dr. Hyde？

W: So, what seems to ha the problem today？

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

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

M: Okay. Uh...

W: Hum. Wow! I've never seen one like this before. Let me try this.

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

W: Well, there is a major cavity in one of your wisdom teeth. Hasn't this given you any trouble？

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

W: 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.

M: Uh, well, that sounds painful!

W: Don't worry. I've done this once before. Nah, just relax.

M: Wait! Aren't you supposed to give me something to dull the pain？

W: Uh, Oh yeah. I almost forget. We can use a local anesthetic to minimize the discomfort you might feel. Or you can just grin and bear it.

M: Nah, nah, nah! Put me under! 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 leeks like my other teeth？

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

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

W: Okay, pleasant dreams. Drill please.
