How long has Teeth Whitening been a thing?

Let's discuss the history of Teeth Whitening

Teeth whitening has been practiced for centuries, with evidence of various methods being used as early as ancient Egypt. In ancient times, people would use a combination of ground pumice stone and vinegar to scrub their teeth and achieve a brighter smile. Other common methods included rubbing the teeth with a mixture of salt and charcoal, or using a rough linen cloth to scrub the teeth.



In the 18th century, dentists began experimenting with more advanced methods of teeth whitening. One of the earliest methods involved the use of nitric acid, which was applied to the teeth and then neutralized with a solution of soda. This method was effective but also very dangerous and could cause serious damage to the teeth and gums. In the early 20th century, hydrogen peroxide became a popular teeth whitening agent. Dentists discovered that applying hydrogen peroxide to the teeth could bleach them without causing any significant damage. However, early hydrogen peroxide formulations were relatively weak, and it could take several treatments to achieve the desired results. In the 1980s, carbamide peroxide, a more stable and longer-lasting version of hydrogen peroxide, was introduced as a teeth whitening agent. Carbamide peroxide breaks down into hydrogen peroxide and urea, which helps to keep the hydrogen peroxide active for a longer period of time. This made teeth whitening treatments more effective and efficient. In the 1990s, the first commercial teeth whitening products were introduced, including over-the-counter whitening strips and gels. These products were a major breakthrough, as they made teeth whitening accessible to the general public and allowed people to achieve a brighter smile without visiting a dentist.




Today, teeth whitening remains a popular cosmetic procedure, with a wide range of options available, including in-office treatments, at-home kits, and over-the-counter products. While the basic principles of teeth whitening have remained the same, the technology and techniques used have evolved significantly, making it safer, more effective, and more accessible than ever before.
