A shattered grin, a wornout crown, a discolored incisor. How do our broken pieces define us? For The American Scholar, Joshua Bodwell offers a brief autobiography in dental work, examining the ways in which a broken tooth and a handful of interventions shaped his self-perception over decades. He also chews over (sorry) a select literary history of teeth, from Chaucer to Raymond Carver, and seems to ask virtually everyone in his life about their own smiles. His essay is an engaging study of imperfection, of a type many folks live with but might easily hide.

I left my chipped tooth untouched for a long time. It continued to discolor. I suppose I accepted it. Maybe it did make me look, as my friend suggested, tough. At the very least, it gave me an air of wildness. Or maybe it was because I was without dental insurance and acceptance was the easiest path. For long periods, I forgot about my tooth entirely. Until, of course, I met someone new who would ask, assuming it was recent, “What happened to your tooth!?” With that I went tight-lipped.

Then a surprising thing began to happen. As I got older, became a father, moved into a more demanding career, I found that I thought about my tooth less and less. At least, I think I did. I mean, I must have: There are photos of me with friends from this period, laughing without reserve, my half fake tooth on full display. A strange thing was happening to my unchipped front tooth, too: It began to seem more perfect than it actually was simply because it shared the stage with a chipped partner.

Ready to test your knowledge of hue, value, and saturation? Rivka Galchen’s latest for The New Yorker is a trove of fascinating details about our understanding of color. Galchen opens with the buzziest tidbit: an experiment conducted by a vision scientist who used a laser to stimulate a selection of his own cone cells and glimpse a color unknown outside of his laboratory. From there, she roams—through philosophy and art history, from studios to pigment shops—complicating our understanding of perception with each new turn of her titular question.

In the children’s novel “The Midnight Fox,” by Betsy Byars, the main character daydreams about digging in his back yard and coming across a “brand-new color.” A friend of mine remembers being captivated by this scene, and trying to picture the color. “I felt like I could conceive of it, but I couldn’t see it,” she said. The eighteenth-century Scottish philosopher David Hume considered at length whether a person who had seen every shade of blue except for one would be able to picture that one un-experienced shade; he concluded that the answer was yes. In my youth, I spent an afternoon wondering if I would have been able to imagine the fluorescent yellow of highlighter markers if I’d never seen it.
