Wisdom

W H Y do they call them wisdom teeth? So my wisdom teeth have been coming in for the last two years now. And I finally made an appointment to get them taken out. Why do some people have 4 and some only 2.... I was one of the lucky ones that only have 2. I'm not looking forward to it at all. All I know is, they better put me to sleep while they take them out. Mine area also weird, the come in and then they go back down under the gum line. Wisdom teeth., got to love them.
