Considering how synonymous Listerine is with oral hygiene these days, it might be a little hard to imagine it being used for anything else. But believe it or not, Listerine was originally marketed as an all-purpose antiseptic with advertised uses ranging from cleaning floors to curing gonorrhea.

Oh yeah and also… dandruff?

The original formula for Listerine was created by Dr. Joseph Lawrence in 1879, and named after Joseph Lister – the pioneer of modern antiseptic surgery.

It was initially sold as a general germicide and cleansing agent, and also sold to dentists after it was found to be a highly effective sanitizer for oral wounds.

By 1914, it was popular enough to become the first over-the-counter mouthwash sold in the United States.

Despite this success, the brand’s owners, Lambert Pharmacal Company felt they could boost sales even further. That’s when Jordan Lambert and his son, Gerard, came up with a brilliant and aggressive new marketing plan.

Going off the product’s already proven track record as an oral antiseptic, they decided to focus their marketing message by presenting Listerine as the solution to bad breath.

The only problem was that people in those days weren’t all that concerned with bad breath and didn’t think their breath was bad enough to warrant special attention.

But the Lamberts weren’t going to give up easily, and in the early 1920s, they decided to use a somewhat unique tool (for the time) to help sell more product: fear.

They took the Latin word for breath (“halitus”) and combined it with the Greek suffix for medical conditions (“-osis”) to create a new term for bad breath: “halitosis.” While this name had been kicking around previously, the Lamberts took it and ran with it.

With this much more medical-sounding name for a common problem, they then set about preying on people’s insecurities by making them think they had a medical condition that was grossing all their friends out, but everyone was too polite to tell them.

During this time, society was changing as more and more people were joining the workforce and moving to the city. Suddenly, people were working in close quarters with total strangers and men and women were working side by side.

Listerine capitalized on the anxiety these situations created, with a special focus on young women looking for a husband. Their ads often featured an attractive, but dejected-looking young lady who kept getting turned down by men. She’s obviously pretty, so what’s to blame for her lovelessness? The silent and all-too-common affliction of halitosis.

Let’s be clear: Listerine didn’t invent bad breath itself. That’s been around since pretty much forever, and our ancient ancestors had plenty of their own recipes for ways to make your breath smell less funky.

However, bad breath wasn’t really considered a catastrophic shortcoming – it was just another part of life. Listerine changed that perception so completely, that advertising scholar James B. Twitchell once wrote that, “Listerine did not make mouthwash as much as it made halitosis.”

This aggressive campaign was a runaway success, and the company’s sales went from $115,000 to over $8 million in just seven short years!

Oddly enough, the company did continue to market other uses for the product as well. Most notably, they tried to sell Listerine as a remedy for colds and sore throats until 1976, when the Federal Trade Commission found these claims to be misleading and ordered them to stop.

Now, we aren’t saying that using mouthwash doesn’t help with bad breath. However, it is important to remember that most dentists agree that proper brushing and flossing are much more important when it comes to fighting plaque and maintaining overall oral health.

One of the biggest mistakes that people make is thinking that rinsing with mouthwash can make up for being negligent with the other two. Furthermore, the alcohol content in most commercial mouthwash can potentially dry out your mouth – which actually makes bad breath worse. If this happens to you, you may want to consider a non-al**holic alternative.

Ultimately, if you feel like using mouthwash works for you, you should keep using it.

Just know that the average person’s breath is probably fine on a daily basis (provided they’re maintaining a regular brushing and flossing routine). Mouthwash is just a nice bit of extra insurance!
