Khloé Kardashian (2013)
Age at the Time: 28
Why: Her dentist, Kevin B. Sands, revealed the Kardashian simply wanted an even prettier smile! “She happens to have one of the most beautiful smiles I’ve ever seen,” Dr. Sands told 'Radar' about her Invisalign choice. “But she’s a perfectionist and so am I, so it was just something we knew we could do. We’ll take her from a 9.5 to a 12! Her teeth are just slightly crooked and rotated, most people wouldn’t notice, that’s how minor it is.”
