I remember back in the second grade, when our teacher asked us how many sets of teeth we grow in our lifetime, I genuinely thought that we went through five sets of teeth. I was so disappointed, because here I was, 7 years old, and I had already started losing my first set! How would my second set of teeth ever make it past the time when I'm fourteen or fifteen?

Ever had that strange dream where your tooth would feel loose, then you'd reach into your mouth and effortlessly yank it out? Every time I wake up from one of those, I'd jiggle each tooth to make sure that they're still securely attached to the inside of my gums.
