You may have opened up a history textbook on the Roman Empire recently and wondered, ‘Does urine whiten teeth?’

You heard right; urine was once used as a bleaching agent by the ancient Romans to clean their teeth and dye other household items, like their clothing. 

But now, you can turn the page on antiquated teeth whitening methods and explore innovative modern products by SNOW instead, which can offer you whitening solutions that are effective, safe, and taste great too. 

Let’s dive in! 

What this article covers:

The History of Urine in the Roman Empire

In ancient Rome, urine played an unexpected role in daily life.

Urine's Role In Roman Industry

Urine was used to clean dirty clothes, thanks to the ammonia found in it. People would earn a living by collecting urine and then using it for purposes like soaking animal skins and tanning animal hides. The urine industry was so significant that a urine tax was even imposed at one point, helping support various trades and contributing to the economy of ancient Rome.

Urine and Teeth Whitening

But did urine make teeth whiter? The ancient Romans certainly brushed their teeth with the stuff, believing that the ammonia in urine could clean and whiten teeth. While it sounds absurd today, it highlights the resourcefulness and innovation of ancient civilizations, even in personal hygiene. 

Why Whitening Products Are the Best Alternative to Urine

Drawing from our experience, though, we must emphasize that using urine to whiten teeth isn’t safe or effective nowadays, and it doesn’t taste that good either. In modern times, we recommend sticking to safe, proven methods and exploring our commercial at-home whitening products.
