Ancient Methods

Ancient civilizations had some peculiar methods for teeth whitening. Michael Regilio explains that Romans used urine as a bleaching agent due to its ammonia content, which was also employed in laundry 1. This practice highlights the lengths to which people went to achieve white teeth, even if it meant using unconventional substances. Jordan Harbinger humorously notes the irony of trusting barbers to file and apply acids to teeth, a method that often ended disastrously 2.

Despite the bizarre methods, the desire for white teeth has been a constant throughout history, symbolizing beauty and wealth.

   

Modern Techniques

Modern teeth whitening techniques have thankfully evolved from their ancient counterparts. Today, hydrogen peroxide and carbamide peroxide are the most common agents used, offering a safer alternative to historical practices 1. Michael Regilio mentions that while these methods are generally safe, they can cause increased tooth sensitivity, and there are rare cases of adverse reactions 2.

For the most part, it's safe. If you want white teeth, go for it.

--- Michael Regilio

Jordan Harbinger observes that the pursuit of ultra-white teeth is prevalent, especially in Hollywood, where the combination of veneers, whitening, and lighting can create an almost surreal effect.
