Make Do With What You Have
People often cleaned their mouths by simply rinsing with water. Remember, this was a time when toothbrushes and toothpaste didn’t exist, so they did the best they could. They often cleaned their teeth with a piece of cloth, simply wiping back and forth until satisfied.
Public Bathing
While the upper class had their own personal bathtubs, the rest of the population used public baths. These baths saw hundreds of people every day, and the water was rarely changed. The stench of the bath was so bad that people would tie herbs or flowers around their wrists and smell in the good scents while bathing.
