I wonder if Letterman has this problem

I have a tiny gap between my two upper front teeth, and I'm slightly obsessed over it. It's not overly diastematic; it's just a fraction of a millimeter. Still, I'm obsessed with making sure there's a good air flow in the gap at all times. After eating anything, if there's any sort of matter left behind in the gap, I will stop whatever I'm doing and work on clearing it out. I usually keep floss in my desk, and when I don't have that, I'll use a piece of paper. Sticky notes work well, business cards even better. All day long, I'm testing the air flow; anything that gets in that gap will make it squeak a little bit, which has to be annoying to my coworkers.
