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 plaque 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 anesthetic or nitrous oxide ... laughing gas... to minimize the discomfort 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 alloy filling instead of a porcelain one. It'll probably last longer. Patient: Okay, well whatever. Let's get it over with. Dentist: Okay, pleasant dreams. Drill please., Question: When does the man feel discomfort?
