W:Hi, Dr. Hyde.
M:So, what seems to be the problem today?
W:Well, 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, 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 it sometimes hurts when I try some grapefruit or an ice-cream. Is it really bad?
M: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.
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 I recommend a high-strength silver alloy filling instead of a porcelain one. It’ll probably last longer.
W:QK, well, whatever. Let’s get it over with.
M:Okay, pleasant dreams. Drill please.
