I don’t know when I read Neal Stephenson’s Cryptonomicon for the first time. My first post here was back in 2003. I linked to a horrifying (to me) passage that deserves an encore.

Wisdom. A few years ago, when Randy became tired of the ceaseless pressure in his lower jaw, he went out onto the north-central Californian oral-surgery market looking for someone to extract wisdom teeth. His health plan covered this, so price was not an obstacle. His dentist took one of those big cinemascopic wraparound X-rays of his entire lower head, the kind where they pack your mouth with half a roll of high-speed film and then clamp your head in a jig and the X-ray machine revolves around you spraying radiation through a slit, as the entire staff of the dentist’s office hits the deck behind a lead wall, resulting in a printed image that is a none-too-appetizing distortion of his jaw into a single flat plane. Looking at it, Randy eschewed cruder analogies like “head of a man run over several times by steamroller while lying flat on his back” and tried to think of it as a mapping transformation—just one more in mankind’s long history of ill-advisedly trying to represent three-D stuff on a flat plane. The corners of this coordinate plane were anchored by the wisdom teeth themselves, which even to the dentally unsophisticated Randy looked just a little disturbing in that each one was about the size of his thumb (though maybe this was just a distortion in the coordinate transform—like the famously swollen Greenland of Mercator) and they were pretty far away from any other teeth, which (logically) would seem to put them in parts of his body not normally considered to be within a dentist’s purview, and they were at the wrong angle—not just a little crooked, but verging on upside down and backwards. At first he just chalked all of this up to the Greenland phenomenon. With his Jaw-map in hand, he hit the streets of Three Siblings-land looking for an oral surgeon. It was already beginning to work on him psychologically. Those were some big-ass teeth! Brought into being by the workings of relict DNA strands from the hunter- gatherer epoch. Designed for reducing tree bark and mammoth gristle to easily digestible paste. Now these boulders of living enamel were horrifyingly adrift in a gracile cro-magnon head that simply did not have room for them. Think of the sheer extra weight he had been carrying around. Think of the use that priceless head-real-estate could have been put to. When they were gone, what would fill up the four giant molar—shaped voids in his melon? It was moot until he could find someone to get rid of them. But one oral surgeon after another turned him down. They would put the X-ray up on their light boxes, stare into it and blanch. Maybe it was just the pale light coining out of the light-boxes but Randy could have sworn they were blanching. Disingenuously—as if wisdom teeth normally grew someplace completely different—they all pointed out that the wisdom teeth were buried deep, deep, deep in Randy’s head. The lowers were so fir back in his jaw that removing them would practically break the jawbone in twain structurally; from there, one fuse move would send a surgical-steel demolition pick into his middle ear. The uppers were so deep in his skull that the roots were twined around the parts of his brain responsible for perceiving the color blue (on one side) and being able to suspend one’s disbelief in bad movies (on the other) and between these teeth and actual air, light and saliva lay many strata of skin, meat, cartilage, major nerve-cables, brain-feeding arteries, bulging caches of lymph nodes, girders and trusses of bone, rich marrow that was working just fine thank you, a few glands whose functions were unsettlingly poorly understood, and many of the other things that made Randy Randy, all of them definitely filing into the category of sleeping dogs.
