• Experts analyzed searches for British royal family members that contained the terms "smile" and "teeth" to create their ranking
  • Kate Middleton topped the list with 36,000 searchers per year
  • Meghan Markle came second with around 17,400 searches about her smile annually

Kate Middleton has the most popular smile among British royal family members, according to a new report.

Altima Dental recently released data on which member of the royal family has the most-searched smile. The Canadian dental care experts analyzed the number of Google searches for British royal family members that contained the terms "smile" and "teeth" to create their ranking of the top five most popular royal smiles, according to Marie Claire.

The Duchess of Cambridge topped the list with 36,000 searchers per year. Middleton's teeth alone are searched online around 2,400 times a month, while her smile gets around 600 searches per month.

Middleton won by a landslide over her sister-in-law Meghan Markle, who came second with 17,400 searches about her smile and teeth annually. According to the report, the phrase "Meghan Markle teeth" is searched on Google about 1,000 times a month.

Prince Harry ranked third on the list with 15,000 searches, while Lady Louise Windsor, the daughter of Queen Elizabeth's youngest son Prince Edward and his wife Sophie, Countess of Wessex, ranked fourth with 10,800 searches annually. The Queen completed the top five with 7,800 searchers per year.

"The royal family are recognizable worldwide and incredibly influential, so it is exciting to see just how much of an impact they have, even down to their smiles," a spokesperson for Altima Dental said in a statement.

They continued, "It is fascinating to see whose smile the public is most interested in, with the Duchess of Cambridge topping the list. Her smile is iconic—therefore, it is unsurprising that the public is Googling her teeth and taking inspiration."

Dental care experts aren't the only ones who have noticed the future queen consort's smile as it has also received many praises from royal fans and social media users.

"Beautiful smile," one netizen wrote on Twitter.

"When someone has an authentic smile that comes from true happiness, people can tell. That's why hers is so popular," another royal fan wrote of the duchess.

Royal expert Katie Nicholl, author of "Kate: The Future Queen," previously shared a sweet story about Middleton's favorite teacher Dr. Robert Acheson, the former headmaster of St. Andrew's Prep School, encouraging her to keep smiling.

"When Dr. and Mrs. Acheson left the school, Kate presented them with a teddy bear that everyone in the family had signed. She had carefully inscribed it with the words that Dr. Acheson had instilled in her: 'I’ll always keep smiling,'" Nicholl wrote.

"She had the most fabulous smile, and I always told her, whatever happens in life, keep smiling," Dr. Acheson later said, explaining the significance of his message.

Middleton wore braces when she was 12 and had teeth whitening done before her wedding to Prince William in 2011. The work was reportedly done by a London-based orthodontist named Dr. Didier Fillion.

Bernard Touati, a friend and colleague of Fillion, previously shared his thoughts on the appeal of Middleton's smile. "You know why [her teeth] look so good? Because they are not absolutely aligned," he told The Times in 2011, per Marie Claire. "That is what we like, a natural healthy smile."
