The Crazy (and Disgusting) History of Mouthwash

For as long as humans have been using tools, we’ve been cleaning our teeth! From toothbrushes made out of sticks, to dental floss made out of horse hair, we have always been mindful of our oral health. But what about mouthwash? When did we start swishing liquid around hoping for cleaner mouths?

Ancient Roman Mouthwash

There are references to mouthwash in Chinese, Greek, Egyptian and Roman literature, but the most well recorded early instances of humanity using mouthwash comes from ancient Rome, in A.D. 1. The Romans used to buy bottles of Portuguese urine and use that as a rinse. GROSS! Importing bottled urine became so popular that the emperor Nero taxed the trade. The ammonia in urine was thought to disinfect mouths and whiten teeth, and urine remained a popular mouthwash ingredient until the 18th century.

Mouthwash Oddities

People have used some strange combinations – besides urine – as mouthwash. Tortoise blood was once thought to disinfect mouths and clean teeth, and mixtures of berries, mint leaves and vinegar or wine has also been used as mouthwash. In the 12th century, Saint Hildegard von Bingen advocated that swishing pure, cold water could remove plaque and tartar.

Anton van Leeuwenhoek

Known as the “father of modern microbiology,” Anton van Leeuwenhoek is credited for discovering oral bacteria in the 18th century. Upon his discovery, he experimented with a variety of solutions that could kill the bacteria. Leeuwenhoek discovered that he could immobilize and kill bacteria with by dousing them in ammonia and / or alcohol. It is around this time that alcohol became the most popular ingredient used in mouthwash – and it is still used today!

Listerine

In 1865, English doctor Joseph Lister became the first surgeon to perform an operation in a chamber that had been sterilized with antiseptic – a practice that was very uncommon. After Lister’s practice was discovered to reduce mortality rates, it became a more widespread practice.

Inspired by Dr. Lister, Robert Wood Johnson and Dr. Joseph Lawrence modernized surgical sterilization practices and established the iconic company Johnson & Johnson. In 1879, Dr. Lawrence created Listerine – a mouthwash used for cleaning mouths and sterilizing surgical wounds.

By 1895, Listerine was sold to Lambert Pharmaceutical Co. and dentists began to observe the cleaning power of the mouthwash. In 1914, Listerine became the first prescription mouthwash to be sold over the counter in the United States.
