Believe it or not, ancient Romans started their day by gargling with urine as part of their dental hygiene routine!
This practice wasn't born from ignorance - Roman physicians understood that urine contained ammonia, which acted as a powerful whitening agent and antibacterial compound. Wealthy Romans even imported urine from Portugal, believing Portuguese urine was particularly effective for dental care.
The Roman poet Catullus wrote satirical verses about people with gleaming white teeth achieved through this method, and archaeological evidence shows that Romans had remarkably healthy teeth compared to other ancient civilizations.
But Romans didn't stop at urine - they also used crushed bones, eggshells, and oyster shells as abrasive toothpaste ingredients. Some recipes included exotic spices like cinnamon and pepper to improve the taste.
This practice continued well into the Renaissance period across Europe. Even Queen Elizabeth I was said to use urine-based dental treatments, though the specifics of her routine remain historical speculation.
The ammonia in urine does indeed have genuine antibacterial properties and can remove stains - modern chemistry confirms the Romans weren't entirely wrong about its effectiveness, though we obviously have much better (and more pleasant) alternatives today!
So next time you complain about the taste of your toothpaste, remember: you could be starting your morning the Roman way!
