W: Hi, Dr. Hyde.
M: So, what seems to be the problem today?
W: Well, [1] I just came in for a check-up and a dental cleaning.
M: Hum. Open up. Let’s take a look.
W: OK. Uh...
M: Well, [2] there is a major cavity in one of your wisdom teeth. Hasn’t this given you any trouble?
W: Well, the tooth has been bothering me, and [3] it sometimes hurts when I try some grapefruit or an icecream. Is it really bad?
M: Well, we’re going to [4 - 1] remove the decay, and then we’11 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.
W: Uh, well, that sounds painful!
M: Don’t worry. I’ve done this...once before. Nah, just relax.
W: Wait ’Aren’t you supposed to give me something to dull the pain?
M: Uh, chicken. Oh yeah. I almost forgot. We can either use a local anesthetic or laughing gas to minimize the discomfort you might feel. Or you can just grin and bear it.
W: Nah, Nah, nah! 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?
M: If we can save the tooth with a filling, [4 - 2] I recommend a high-strength silver alloy filling instead of a porcelain one. It’11 probably last longer.
W: [4-3] OK, well, whatever. Let’s get it over with.
M: Okay, pleasant dreams. Drill please.
