1920s: Americans started stocking up on Listerine, a former surgical antiseptic (and a former floor cleaner... and a former home cure for gonorrhea) turned treatment for bad breath or "chronic halitosis". In case you hadn't heard, halitosis makes you a total loser.
1950s: Colgate reached back into their fourth grade science projects and tapped chlorophyll -- that green pigment plants use to photosynthesize -- for their newest toothpaste. It helpfully promised to "destroy bad breath originating in the mouth."
1971: After shilling toothpaste and this highly confusing, highly amusing "tooth cream" for women, Binaca attempted to help smelly suitors everywhere through these ads for its golden breath spray.
2000: Pfizer developed dissolvable breath strips, prompting on-the-go halitosis sufferers to grapple with the weird sensation in their mouth for the next thirteen years.
