Newell Sill Jenkins (* December 29, 1840 Falmouth, Massachusetts — September 25, 1919 Le Havre, France) was an American dentist who practiced most of his life in Dresden, Germany.[1] He developed and improved the Jenkins porcelain enamel, thus making a composition of porcelain paste into porcelain inlays, dental crowns and bridges. He is thus the founder of aesthetic dentistry.
