Who invented the first toothpaste in the world?

Did you know that oral hygiene was a top priority in society as early as 5000 BC? Even though the brands of toothpaste that we have today are the most effective in preventing oral disease, the concoctions up until now haven't been too far off.

The world's oldest-known formula for toothpaste was created by Egyptians. They crushed rock salt, mint, dried iris flowers and pepper and mixed them together to create a cleaning powder. Although this concoction is known to create bleeding gums, research suggests it is the most effective compared to most toothpastes used as recently as a century ago.
