Housed at the Mount Vernon Estate, this early pair of Washington’s dentures were by New York City dentist John Greenwood. The teeth are made from a combination of human teeth, cow teeth, and elephant ivory. The base is made out of lead and there are steel springs to help open and close them. Everything is held together with brass wire.
When these were made, Washington had one tooth remaining, so Greenwood left a space in the dentures in order to avoid removing it. As a thank you “[w]hen Washington finally lost this tooth as well, he gave it to Greenwood who saved this cherished item in a special case.”
