What’s a toothbrush?
Before the mid 18th century, toothbrushes weren’t even a thing. People would use all sorts of methods in attempts to clean their teeth.
This included such tactics, such as rubbing their teeth with a damp cloth, thoroughly rinsing their mouths with warm water, and rubbing herbal chewing sticks against the teeth to loosen the dirt and freshen their breath. These were all pretty effective in getting the job done, but nothing surpassed the genius invention of the toothbrush. Hallelujah.
