Origin of the Idiom

Shakespeare Connection
The idiom “set my teeth on edge” is used in two of Shakespeare’s plays: Henry IV, Part 1 and The Winter’s Tale.
In Henry IV, Part 1, the character of Hotspur uses the phrase to express his distaste for bad poetry. He says:
“And that would set my teeth nothing but an edge, nothing so much as mincing poetry.”
In The Winter’s Tale, the character of Leontes uses the phrase to describe the sound of music that he finds unpleasant.
“The music of his tongue hath set my pugging tooth on edge.”
Here, Leontes is saying that the sound of the music is so unpleasant to him that it makes his teeth feel like they are on edge. The phrase is used figuratively to mean to cause someone to feel disgust or revulsion.
The multiple use of the idiom in Shakespeare’s plays suggests that it was already a well-established phrase in the English language by the 16th century.
