For celebrities, a beautiful smile is their lifeline. It’s their secret weapon to land their dream roles, score endorsement deals, and amass a legion of fans. Most would even go to great lengths to achieve the most perfect grin.

But how exactly does one’s smile qualify as beautiful? And which celebrities exemplify such criteria? Science has the answer.

What Does a Beautiful Smile Mean?

A beautiful smile is more than just a flash of teeth. For a smile to be beautiful, many believe it should radiate joy to people around you. Also, it should have the power to make others feel better, reduce stress, and capture attention. Still sounds generic?

According to science, a beautiful smile is measurable through the golden ratio. This mathematical concept represents a specific ratio (approximately 1.618) found in natural objects and art, like the pyramids of Giza or the Mona Lisa. Consequently, a smile becomes aesthetically pleasing if certain facial proportions align with this principle.

Additionally, scientific studies suggest other factors that contribute to a stunning smile. Research by the Journal of Dental Clinics of North America found that teeth size, curve, colour, shape, and overall mouth size can impact the attractiveness of a grin.

Celebrities With Beautiful Smiles 

Which celebrities fit the bill? News site Manchester TV rounded up a list of stars with the most beautiful smiles based on scientific factors. Here’s a closer look at the top scorers, ranked in ascending order based on their golden ratios. 

1. Gal Gadot

The Wonder Woman star scored 45.10% for golden ratio and 92.89% for teeth brilliance. With such numbers, her dazzling smile can surely light up even the darkest room. A true modern-day goddess!

4. Ellen Pompeo 

Veteran actress Ellen Pompeo, who rose to fame with TV dramas Law & Order and Grey’s Anatomy, has more than her acting prowess up her sleeve. With a golden ratio approximation of 53.93% and a teeth witness score of 87.75%, her smile earns her a well-deserved spot on this list.

6. Adam Sandler

Her sensational smile could just be the reason she earned the title of the world’s highest-paid actress in 2018 and 2019. 

How You Can Achieve a Beautiful Smile 

Earning a spot on this list required effort and multiple visits to the dentist. Yes, even celebrities need to work hard to get their smiles red carpet ready. So, if you want to be as confident as the stars here, be open to undergoing treatments and optimising your golden ratio.

Consult your doctor about the appropriate solutions for your dental and oral concerns. Remember: no one size fits all. If you have misaligned teeth, you might need orthodontic treatment. You can either go for traditional metal braces or ClearCorrect aligners, which are more subtle and comfortable. Either way, cooperate with your dentist to achieve your desired results.

Learn to be patient, too. You won’t just wake up one morning with the most beautiful teeth. Plus, you’ll need to take essential steps to maintain your progress. Just keep at it! Stay proactive, and soon, you’ll be dazzling the people around you with that winning smile.
