The TikTok Teeth Shaving trend emerged as a controversial DIY dental hack where creators used nail files to level out their front teeth, leading to widespread condemnation from dental professionals. The meme usually highlights the gap between social media beauty hacks and medical common sense, often featuring a split-screen between the person filing their teeth and a horrified dentist or a future version of themselves suffering from extreme sensitivity. It serves as a cautionary tale wrapped in dark humor, poking fun at the lengths people go for aesthetic trends seen on social media platforms.
