Let’s Talk About the History of Teeth Whitening

It’s safe to say that everybody wants to have a confident, radiant smile. Whether for a special event, a boost in everyday confidence, or simply because you love the feeling of sparkling teeth, the desire for a brighter grin is timeless. But have you ever stopped to wonder just how long people have been trying to achieve it? So, when did teeth whitening start? Brace yourself because the quest for a brighter smile dates back thousands of years, and some of the historical methods are, well, truly unforgettable (and not in a good way!). Today, we’ll dig deep into the fascinating history of teeth whitening, from the incredibly bizarre ancient remedies to the safe, effective, and beautifully aesthetic techniques we use today at SmileBar.

The (Sometimes Questionable) Ancient Roots of Teeth Whitening

Believe it or not, our ancestors were just as keen on pearly whites as we are—long before Instagram filters existed. Here are some interesting bits of history to know:

Ancient Egyptians (c. 4000 BC)

The Egyptians were known for their meticulous hygiene and beauty standards. So, it’s not surprising to know they were pioneers in teeth whitening. They would make an abrasive paste using ground pumice stone mixed with wine vinegar. This crude scrub aimed to remove surface stains and was seen as a mark of status and cleanliness.

Ancient Romans (c. 1st Century AD)

Here’s where things get interesting. The Romans discovered that urine contained ammonia, a known bleaching agent. Yes, you read that right. They would rinse their mouths with aged urine to achieve a brighter smile. It’s one of those wild facts about teeth whitening that truly makes you appreciate modern dentistry. While it’s scientifically plausible due to the ammonia, the “ick” factor is undeniable.

Other Ancient Civilisations

The Mayans weren’t just building pyramids; they also reportedly used crushed shells or charcoal for abrasive dental cleaning. Across Asia, various herbal remedies and natural abrasives were also employed, all aiming for a similar bright outcome.

The Less-Than-Glamorous Middle Ages & Renaissance

Fast forward a few centuries and dental aesthetics took a back seat to pain relief. However, attempts at whitening still existed, though they were often brutal.

In Europe, barbers-surgeons (who did a bit of everything from haircuts to tooth extractions) sometimes took a rather aggressive approach. Their methods included filing teeth with rough metal files and then applying strong, corrosive acids like nitric acid. While the immediate result might have been whiter teeth, the long-term consequences were devastating: severe enamel erosion, extreme sensitivity, and irreversible dental damage. This was definitely a “do not try this at home” situation.

The Dawn of Modern Dentistry (and Safer Whitening) – 18th to Early 20th Century

As the understanding of anatomy and chemistry grew, so did the methods of dentistry. By the 18th and 19th centuries, early dental professionals began to emerge, moving away from the barbaric practices of barbers-surgeons. While still experimental, they introduced slightly more controlled (but still damaging) acids like oxalic and hydrochloric acid for oral whitening. The focus was gradually shifting towards more scientific approaches.

The late 19th and early 20th centuries marked a significant turning point with the discovery and cautious introduction of hydrogen peroxide in dentistry. Though hydrogen peroxide was initially used for its antiseptic properties, its potential as a teeth whitener gradually came to light. Early applications were basic, typically involving the soaking of cotton pellets in diluted hydrogen peroxide before applying them to the teeth. However, these practices laid the foundation for effective teeth whitening techniques.

The Scientific Leap: Mid-20th Century to Today’s Sparkle

This is where the history of teeth whitening truly gets exciting and directly leads to the comfortable, effective treatments we enjoy today.

Mid-20th Century (1960s-70s): The Accidental Breakthrough!

One of the most pivotal facts about teeth whitening came from an unexpected place. Dentists noticed that patients using a peroxide-based antiseptic solution in custom mouthguards for gum health also experienced significantly whiter teeth! This accidental discovery led to the development of “Nightguard Vital Bleaching,” using carbamide peroxide—an ingredient that breaks down into hydrogen peroxide—as the active whitening agent. This innovation was a breakthrough in dental care.

Late 20th Century (1980s-90s): Mass Popularisation

With the discovery of carbamide peroxide’s efficacy, at-home tray-based systems became widely available. Simultaneously, in-office “power bleaching” methods, often incorporating specialised lights or lasers to accelerate the process, began to gain traction.

21st Century and Beyond (The SmileBar Era!)

Today, we stand on the shoulders of all these historical developments. The gels are refined, offering varying strengths with reduced sensitivity. Advanced light activation technology helps attain faster and more effective results. The focus is squarely on safety, comfort, and achieving predictable, beautiful outcomes under expert guidance.
