Sen-Sen was a type of breath freshener originally marketed as a "breath perfume" in the late 19th century by the T. B. Dunn Company and then produced by F&F Foods until the product's discontinuation in July 2013. Sen-Sen bore a strong resemblance to Vigroids, a liquorice sweet made by Ernest Jackson & Company, Ltd.
Sen-Sens were available in small packets or cardboard boxes. Similar to a matchbox of the time, an inner box slid out from a cardboard sleeve revealing a small hole from which the tiny Sen-Sen squares would fall when the box was shaken.
Sen-Sen's ingredients were licorice, gum arabic, maltodextrin, sugar, and natural and artificial flavors.
Sen-Sen's distinctive, strong scent, its nostalgic association with earlier time periods (particularly the 1930s through the 1950s), and its frequent use in covering up the odoriferous evidence of perceived vices such as drinking and cigarette smoking has led to many references in multiple forms of media.
- A brief reference occurs in the 2004 Martin Scorsese major motion picture The Aviator. Howard Hughes and his press agent Johnny Meyer are speaking to each other at a "hip" Hollywood club. The pair are interrupted by a cigarette girl with the line: "Cigar, cigarettes, Sen-Sen?"
- Another brief reference is in The Wayward Bus by John Steinbeck, Chapter 7.
