Just barely. The term comes from the Book of Job (19:20), in which Job tells Bildad of his troubles. He says, “My bone cleaveth to my skin and to my flesh, and I am escaped with the skin of my teeth,” meaning that hardly anything is left of his body. The expression still is used almost exclusively to mean a narrow escape. However, Thornton Wilder used it as the title of a play, The Skin of Our Teeth, an allegory of how mankind survives that won the Pulitzer Prize for drama in 1943.
