These weren't "clean" teeth, by the way. There were still chunks of person still on them. Chunks.
No, I'm not a psychopath trying to forge my very own tooth-crown so I can rule over The Land of Mouths with an iron fist. This is a legitimate business. See, dentists remove teeth from patients on a semi-regular basis. Some of those teeth have crowns and bridges that contain gold, platinum, and/or palladium. Those are called PFMs -- porcelain fused to metal. Most dentists send their waste teeth directly to refineries, like these guys:
Never underestimate the lengths the "cash for gold" industry will go to.
But a lot of office administrators and dental assistants either don't know about the refineries or want to make a quick buck all for themselves -- hence the clandestine meetings in parking garages and alleys. So for about a month, it was my job to trawl the dental offices of Los Angeles County in search of jars of teeth. Once I'd picked out the ones to buy, I'd take them back to my boss, who'd dump them in a Ziploc bag and ship them off to a refinery himself. I was essentially the middleman in a cash-for-body-parts business.
