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 they discontinued the product in July 2013. Sen-Sen bore a strong similarity 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, anise, 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 1960s), and its frequent use to cover up the odoriferous evidence of perceived vices such as drinking and cigarette smoking led to many references in various media.
- the most famous reference occurs in Billy Joel's smash hit 'Keeping the Faith' released as a single in 1984 when the songwriter, reminiscing about coming of age in the 1960s, mentions "a fresh pack of Luckies and a mint called Sen-Sen". The album An Innocent Man from 1983 contains this title and other well known hits.
- A brief reference occurs in the 2004 Martin Scorsese 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.
