Mostly True Rome

Ancient Romans used urine as mouthwash and teeth whitener due to its ammonia content, and the Roman Empire taxed liquid waste collection.

Infact verdict: Mostly True (73/100).

The claims about ancient Romans using urine as mouthwash and teeth whitener, and the Roman Empire taxing liquid waste, are based on historical practices. Urine was indeed used for its ammonia content, which acts as a bleaching agent. However, no external evidence was found to corroborate these claims directly. These practices are documented in historical texts, making them plausible. The claim about the Roman tax on urine is also supported by historical records, such as the 'vectigal urinae' tax. Despite the lack of direct evidence in the search, these claims align with well-established historical knowledge.
