It puts a different spin on the entire story.

"In the 1780s, a French dentist tried unsuccessfully to transplant teeth into Washington’s mouth, and some evidence exists that several enterprising slaves at Mount Vernon sold their teeth for this experiment."

"Unlike most of the Founding Fathers who owned slaves, Washington freed his slaves in his last will and testament and set aside funds to help them begin a new life. He wrote on several occasions that he was opposed to slavery, noting that "there is not a man living who wishes more than I do, to see a plan adopted for the abolition of it."

Slaves of the eighteenth century sometimes turned to the perfectly acceptable means of making money by selling their teeth to dentists. Since at least the end of the Middle Ages, poor people had often sold their teeth for use in both dentures and in tooth-transplant operations for those wealthy enough to afford the procedures. Sometimes the teeth were perfectly healthy; others were diseased and needed to be pulled anyway. 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. He seems to have had an extensive practice in tooth transplants, but the results of the procedure were short-lived, usually less than one or two years. Transplantable teeth were hard to come by, and in 1783 Le Moyer even went so far as to advertise in the New York papers for "persons disposed to sell their front teeth, or any of them," netting the donor two guineas (forty-two shillings) per tooth.

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
