Do you wish your teeth were straighter? Your inhibitions about being a metal mouth, even if only for a year or two, could be enough to prevent you from achieving your perfect smile.

Fortunately, there’s another way. You can beautify your smile at Speaks Orthodontics the way celebrities do: with Invisalign! You’ll be shocked to learn that some of your favorite movie stars and public figures have used Invisalign – some while they were younger, but many while they were right in the spotlight.

Tom Cruise

In 2002 when he was filming Minority Report, Tom Cruise donned almost entirely invisible braces to discreetly straighten his teeth. At the time he was 40, and he opted for an invisible look so as not to tarnish his dashing good looks while being the center of attention in Hollywood.

Justin Bieber

While this young pop star makes headlines more these days for his bad behavior than his music, Justin Bieber has donned beautiful pearly whites since he used Invisalign back in 2011. He was spotted wearing them at the BRIT Awards. He also reportedly removed the invisible braces during an interview with a reporter near that same time.

Zac Efron

He started as a teen sensation in High School Musical, but once he started taking on more serious, adult roles, Zac Efron decided it was time to close the gap between his front teeth, called a diastema. How did he do it? With Invisalign.

Oprah Winfrey

Among the most influential people in the world, it’s no wonder Oprah Winfrey chose Invisalign to straighten her teeth. She felt so confident with the aligners that she didn’t hesitate to wear them in front of the camera while filming her award-winning talk show.

Kate Middleton

As reports have it, Duchess Kate Middleton donned Invisalign for six months leading up her to wedding to Prince William. Her French orthodontist recommended the aligners to perfect her smile just in time for the big day.

Keira Knightley

Another famous public figure from England, Keira Knightley decided Invisalign was the best way for her to correct several shifted teeth. She had a lovely smile to begin with, but Invisalign was the perfect way to align every tooth.

Katherine Heigl

In an interview with Extra magazine in 2008, Katherine Heigl hyped up her invisible braces, which she was wearing at the time. The interviewer couldn’t even tell until Heigl pointed it out. “I had crooked teeth my whole life pretty much, and I only started caring about it when I was going to get married. I want my teeth straight for my wedding photos!”

Khloe Kardashian

In 2013, Khloe Kardashian decided an Invisalign treatment was the right method to straighten her teeth and perfect her smile. Thanks to the wire-free option, she did so without drawing unwanted attention to her mouth. Still, she wasn’t shy about it, even tweeting “thank you” to her dentist for handling the entire process.

Serena Williams

This star tennis player wanted to make sure she could smile with confidence while celebrating all her big wins. When she was 16, Invisalign straightened her teeth and gave her the stunning smile she has today.

Eva Longoria

In 2011, this actress, best known for her role in Desperate Housewives, decided her smile needed a little tweaking. Instead of turning to traditional metal braces, she chose Invisalign to discreetly straighten her bottom teeth.
