Researchers excavating an ancient burial site in west-central Mexico have unearthed a man’s skeleton containing the earliest American example of intentionally modified teeth.

The discovery, announced June 14 by Tricia Gabany-Guerrero of the University of Connecticut in Storrs and her colleagues, dates to between 4,570 and 4,332 years ago.
Although most of the skeleton’s teeth exhibit normal levels of wear, the upper-front teeth were filed down, possibly to make room for a ceremonial denture that would have been fashioned from the palate of an animal such as a wolf or jaguar, Gabany-Guerrero says. “The teeth were filed down so much that the pulp cavities were exposed, leading to an infection,” she notes.
