Your 'Perfect' American Smile Could Actually Make People Uncomfortable Overseas

Tawanna Marie Woolfolk didn’t announce her presence during the 36-hour bus journey across Western Australia. Instead, her teeth did the talking.

She was heading to the Dampier Peninsula to conduct fieldwork within Aboriginal communities. At some point along the trip, she smiled at the person sitting beside her. The reply was straightforward: “You have a nice smile. Are you American?”

This same remark recurred repeatedly over the weeks she spent living in the isolated community. Observations like “your teeth are so white,” or “they are really straight,” were always stated as identifiers rather than compliments. Her smile revealed her nationality.

Woolfolk had never viewed her smile in that light. Back in the U.S., it was ordinary. Abroad, it was a giveaway.

The smile that revealed Woolfolk’s origins is one Americans invest heavily in, with the U.S. cosmetic dentistry market projected to approach $20 billion this year. Many aim for teeth that are dazzlingly white and perfectly aligned to the millimeter. Yet, outside the United States, that very smile can provoke reactions ranging from bewilderment to distrust to unease.

Amit Raj, based in Scotland and working with clients across both sides of the Atlantic, explained that in the U.K. there’s already a term for it: turkey teeth. Originally, the phrase mocked Britons who returned from Turkey sporting cheap, overly done veneers, but now it applies to any smile that appears excessively flawless. “Whether it’s veneers or not, people just call them turkey teeth,” Raj said.

The label has even spread to dating platforms. “Scroll through Tinder in the U.K. and you’ll find many profiles where women list men with turkey teeth as a major turn-off,” he noted. It also appears during video calls. While pitching his services to an American executive, Raj found himself distracted. “All I could focus on were those fluorescent white teeth staring back at me.”

Dr. Kimberly Ivett, a dentist practicing in Australia, witnesses that unease regularly. The most frequent concern patients express during consultations is the fear of ending up with a smile that looks American. When she views the smile transformations American dentists promote on Instagram, her immediate reaction is clear.

“Personally,” she said, “it just screams fake to me.” Her patients desire something quite different. “Tastefully white, perfectly proportioned and balanced, and elegantly natural. A smile where you walk down the street and people simply assume you have perfect teeth. They don’t want to enter a room with Uncle Barry shouting across: ‘Hey Stevo, looks like you got your teeth done! Bloody bright, aren’t they?’”

Juan María Solare, originally from Argentina and now residing in Germany, believes the reaction in both cultures goes beyond mere dislike. “In my cultural context, if someone constantly displayed such a smile, it would be viewed as somewhat suspicious,” he said. “The reaction might be: ‘They’re trying to win your trust, but why, and for what purpose?’”

“In the animal kingdom, baring teeth rarely signals happiness. It usually indicates aggression or threat,” Solare explained. “Humans are animals with manners, but primal associations still linger beneath the surface.” In Argentina, smiles typically reveal only the upper teeth and almost never the lower ones. Look at any photo of Lionel Messi smiling, he said, and you’ll notice this.

For Jiri Padour, living in the Czech Republic, the American habit of smiling broadly at strangers caused a specific kind of confusion. “If someone approached you with a big, open American smile, the reaction would be: Do I know this person? Are they trying to flirt?” he said. Such warmth is traditionally reserved for people you already know.

The cultural responses are one aspect. What Americans do to their teeth to achieve this look is another matter entirely.

Dr. Ambereen Fatima trained in India before attending New York University and establishing a practice in Massachusetts. The difference was striking. In India, dentistry was almost purely functional. Patients sought treatment only for broken or severely stained teeth. In the U.S., the requests shifted dramatically. “Patients are often willing to aggressively grind down perfectly healthy, untouched enamel just to obtain a manufactured, symmetrical Hollywood smile,” she said.

She is equally candid about what Americans do at home without professional supervision. In the European Union, over-the-counter whitening products are limited to 0.1% hydrogen peroxide. Anything stronger must be administered by a dental professional. Yet, walk into any American drugstore and far stronger formulas are openly available. “High-concentration peroxide should be regarded as a medical procedure. Whitening without custom-fitted trays can cause chemical burns on gums and permanent enamel damage,” Fatima warned.

That gap between what American patients desire and what the rest of the world considers normal is something Dr. Anabella Oquendo frequently observes.

She leads both the aesthetic dentistry and international programs at NYU College of Dentistry. Growing up in Venezuela, she learned a different standard, valuing warmth and facial harmony over extreme brightness. Many international dentists rotating through her program share a similar philosophy, which is why what surprises them most is not American technology or techniques but the patients themselves. “Patients often arrive with clear expectations, inspiration photos, and very specific demands,” she said. In most countries, patients fully defer to the clinician.

Oquendo’s personal approach focuses on what she terms “perfect imperfections,” enhancing without overcorrecting, refining without erasing what makes a smile unique.

These imperfections are prized in Japan, where slightly crooked teeth, called yaeba, are seen as youthful and attractive, especially among young women. Some even undergo cosmetic procedures to make their teeth appear less straight—paying to achieve what many Americans pay to eliminate.

Back on the Dampier Peninsula, Woolfolk’s smile began to take on a new meaning.

Woolfolk has a gap between her front teeth. At home, that gap always felt like a flaw, but in Western Australia, it became something else. People pointed to it and smiled, revealing their own. “You’ve got one too,” they would say, grinning.

“For literally the first time,” Woolfolk said, “I wasn’t ashamed of my smile.”
