From seeing them looking glamorous on the red carpet or dreamy on the television, we often forget that celebrities also have ordinary flaws. Here is a list of well-known celebrities that have had Invisalign.

Katherine Heigl decided she wanted a perfect smile just before her wedding in 2007. The actress was ecstatic about the convenience of being able to remover the aligners. “It’s awesome because every two weeks you switch to a new retainer. Pretty much the perfect way to describe Invisalign is Netflix for your teeth,” she told In Style Magazine.

Reality TV star, Khloe Kardashian, was in the public eye far more on her journey to self-improvement. After she began losing almost 30 pounds, she decided to straighten her smile with the help of Invisalign at the age of 28.

Desperate Housewives star, Eva Longoria began her treatment at 36 to straighten her bottom teeth with Invisalign. It’s also popular with supermodels: Gisele Bundchen told interviewers that she began her treatment after she discovered that her teeth were moving, making her smile look less perfect.

Other internationally recognised celebrities that opted for Invisalign braces include Justin Bieber, Tom Cruise and Oprah Winfrey. Bieber was very open about his Invisalign treatment as he shared it with his large audience on YouTube and was spotted wearing aligners at ritzy awards galas.
