TikTok bone smashing debunked: what actually builds facial structure

Young men on TikTok have been hitting themselves in the face with rocks and hammers trying to sharpen their jawlines, citing a 132-year-old bone biology principle called Wolff's Law — and oral surgeons are now treating them for nerve damage and microfractures. The science they are quoting is real, but they are applying it so wrong that bone researchers do not even consider it a debate. The actual path to jaw definition is dropping body fat below 15 percent, chewing hard mastic gum to build your masseter muscle, and fixing your posture — none of which require hitting yourself in the face with anything.
