Cavitatus

My dentist recently introduced me to inter-tooth brushes. I have now become addicted to them. There's something very fundamentally satisfying about the sensation of brushing not only the front and back of my teeth, but the space between as well. I carry the tiny brushes with me everywhere. They are a great way to pass time such as when waiting for the bus (see "No. 144" below) or when waiting for the next sentence here to coagulate inside my brain. The same dentist also introduced me to "Tooth Mousse," which is equally addictive. And I fully rejoice these two inventions. Good to see that very low tech still has a place in this world.
