Black Panther isn't just breaking box office records, it's breaking retainers.
It all started with a Tumblr post from an orthodontist. It featured two images of Michael B. Jordan as Killmonger in Black Panther. He wrote, without mentioning a name, that one of his patients came in "for an emergency visit, because she snapped the wire on her retainer watching the movie." In particular, it was the scene when Jordan took off his shirt. "She clenched her teeth so fucking hard she snapped [the retainer]," he wrote.
A screenshot of that post made the rounds on social media. Eventually, the retainer-breaking teen involved saw the story. "My initial reaction was, 'I have to find this girl and I have to be her best friend,'" 18-year-old Sophia Robb later told CNBC Make It. "'We already have so much in common!'" Once she figured out the story was about her, she let everyone know.
