Thanks for the chapter!
About the wisdom teeth guy needs to see a dentist. As for hoping other people don't get them that's futile as everybody has them. Problem with wisdom teeth is that as someone grows up so do their teeth. However, there's only so much room for them to grow before start bumping into each other. What usually (not always,) happens is the wisdom teeth push against the other teeth causing them to get crooked, swing inward/outward, or just feel a little pressured. This can cause bleeding and discomfort. Won't be as bad as the dentist's illustration for Lisa's teeth development in that episode of the Simpson's where she got the economic braces. Hence it's usually a good idea to have them removed in the teenage years when they're easier to remove. I had a lot of upheaval during those years so was a while before got them removed. As a result I only got the painkillers and mild anesthesia so was semi-awake when they got removed. Didn't hurt but was uncomfortable and took him over an hour to remove the four wisdom teeth. So if haven't had them out yet and are over 17 should talk to dentist before becomes an issue.
