When And How Was Toothpaste Invented?
Toothpaste was invented in ancient Egypt around 5000 BC, where a mixture of crushed rock salt, mint, dried Iris flowers, and pepper was used to clean teeth. In the 19th century, toothpaste evolved when soap was added to the ingredients, but it wasn’t until the 20th century that modern toothpaste was developed with fluoride as the active ingredient. Today, toothpaste is available in various flavors and is an essential part of daily hygiene for millions of people around the world.
