Oral hygiene has always been a top priority in society as far as we can remember. Although the toothpaste that we have available today seem to be more effective in preventing oral disease, the ones created in the past weren't too different!
Take a look at this brief timeline:
4th century AD: The Egyptians created the oldest known formula. It was a mixture of crushed rock salt, dried iris flowers and pepper. Even though this was known to create bleeding gums, researchers suggested that it was most effective compared to most toothpastes used as recently as a century ago.
1780: It was known that people were scrubbing their teeth with a powder mainly made of burnt bread.
1824: A dentist (named Peabody) added soap to toothpaste for added cleanliness. However, later on, it was replaced by sodium lauryn sulfate to create a smooth paste.
1873: Colgate produced and launched their nice-smelling toothpaste and it was sold in a jar.
1892: Dr. Sheffield was the first person to put toothpaste in a collapsible tube -- it's been suggested that his version is the most similar to today's version.
1914: Fluoride was added to toothpastes after it was discovered that it significantly decreased dental cavities.
1975: Herbal toothpastes, like Tom's, became an alternative to cleaning teeth without fluoride. It contained ingredients like peppermint oil, myrrh and plant extracts.
1987: Edible toothpaste was invented. It was mainly used by children who were learning to brush their teeth, but it was invented by NASA so astronauts could brush their teeth without spitting into a zero-gravity abyss.
1989: Rembrandt invented the first toothpaste that claimed to "whiten and brighten your smile".
The world of dentistry is always evolving! I wonder what other milestones we'll reach today.
