Washington also had teeth made of ivory and metal alloys to include lead-tin, copper, and silver.
Concerned with his poor dental health and hoping that his original teeth would be fit into his new dentures, the Army general kept many of his pulled teeth in a locked desk drawer at Mount Vernon, according to museum records.
In a 1782 letter to Lund Washington, his distant cousin and temporary manager of the Mount Vernon estate, he requested the teeth be wrapped up and sent to him in Newburgh, New York.
"In a drawer in the Locker of the Desk which stands in my study you will find two small (fore) teeth; which I beg of you to wrap up carefully, and send inclosed [sic] in your next letter to me," says the letter. "I am positive I left them there, or in the secret drawer in the locker of the same desk," he added.
Washington's dentures were made by setting the teeth into artificial lead frames and held in place on the top and lower jaws of Washington's mouth by two metal wires that were curved to the shape of his jaw. While the lower denture was sized to fit Washington's mouth, the upper denture was flat on top.
"There's nothing to hold it in place or shape it to your mouth," said Schoelwer. To join them together, there were two, "very tight silver springs" so that when he opened his mouth, the springs forced the upper denture to rise with his mouth, allowing him to open and close it.
"Because that spring is so strong, it's always pushing against the top of your mouth, so in order to keep your mouth closed, you had to really grit your teeth all the time," she explained, noting his portraits depict how uncomfortable (and painful) this must have been.
In his 1789 inaugural address, Washington mentioned the "frequent interruptions" his health had suffered over his lifetime. At the time, he had a single remaining natural tooth, according to the museum's history.
