George Washington (1732–1799) suffered from problems with his teeth throughout his life, and historians have tracked his experiences in great detail. He lost his first adult tooth when he was twenty-two and had only one left by the time he became president. He had several sets of false teeth made, four of them by a dentist named John Greenwood. None of the sets, contrary to popular belief, were made from wood or contained any wood. The set made when he became president were carved from hippopotamus and elephant ivory, held together with gold springs. Prior to these, he had a set made with real human teeth,"Dentures, 1790–1799". , George Washington's Mount Vernon Estate, Museum and Gardens likely ones he purchased from "several unnamed Negroes, presumably Mount Vernon slaves" in 1784.Mary V.
