Niall Horan
Niall Horan was nothing but a regular Irish teen who auditioned for the X Factor back in 2010. While and his One Direction group didn’t win, they were launched to international stardom in such a short time. He suddenly had more money than he knew what to do with, but he knew one thing: his crooked, boyish smile had to go.
It didn’t take long for the young pop musician to invest in braces to realign his teeth. He didn’t get veneers since he thought it might affect his vocal talents, but instead stuck to a strict program involving retainers and whitening agents.
