John Greenwood (dentist)
From Wikipedia, the free encyclopedia
Dr. John Greenwood (1760–1819) was George Washington's personal dentist and was responsible for designing Washington's famous dentures, which were not wood but carved from hippopotamus tusk. He invented the first known "dental foot engine" in 1790.[1][2]
He was the son of Isaac Greenwood, the first native-born American dentist.
A letter from John Greenwood to Lt. General George Washington on his denture charges, dated 1799, is in the A.D. Black History of Dentistry Collection at Northwestern University.[3]
