How in the world did they come up with that?!? TOOTHPASTE

Evidence suggests that concerns for oral hygiene dated back as long as 5,000 years ago in India, China, Mongolia, and Egypt. People in India chewed neem twigs until they could use it to brush their teeth. Egyptians in the 4th century AD mixed salt, pepper, mint leaves and iris flowers, and called it toothpaste. Romans had their own variation of toothpaste, one that was based on urine.

Throughout the 19th century, ingredients such as burnt bread, pulverized brick, chalk and charcoal were commonly found in different concoctions of toothpaste. It wasn't until the early 20th century that ingredients more commonly found in today's toothpaste, fluoride and baking soda, were used.
