And what history is still taught today:
In 1780 a French dentist named Jean Pierre Le Moyer (also called Le Mayeaur, Le Mayeur, and Joseph Lemaire) came to America, possibly as a naval surgeon with the French forces commanded by the Comte de Rochambeau, and over the next decade treated patients in New York, Philadelphia, Baltimore, Alexandria, and Richmond. […] Le Moyer first treated George Washington’s teeth at his military headquarters in 1783.
The following year, in May of 1784, Washington paid several unnamed “Negroes,” presumably Mount Vernon slaves, 122 shillings for nine teeth, slightly less than one-third the going rate advertised in the papers, “on acct. of the French Dentis [sic} Doctr. Lemay [sic],” almost certainly Le Moyer. Over the next four years, the dentist was a frequent and apparently favorite guest on the plantation. Whether the Mount Vernon slaves sold their teeth to the dentist for any patient who needed them or specifically for George Washington is unknown, although Washington’s payment suggests that they were for his own use. Washington probably underwent the transplant procedure–“I confess I have been staggered in my belief in the efficacy of transplantion,” he told Richard Varick, his friend and wartime clerk, in 1784–and thus it may well be that some of the human teeth implanted to improve his appearance, or used to manufacture his dentures, came from his own slaves.
