Zac Efrons changed appearance has sparked rumors and speculation, with some suggesting that he underwent plastic surgery. However, Efron himself has explained that the changes in his jaw were due to a jaw injury in 2013, not surgery. He mentioned that he almost died after suffering an accident at his home, where he slipped and badly hurt his chin, resulting in a broken jaw and the need to have his mouth wired shut. Efron has expressed amusement at the rumors and emphasized that his altered appearance is a result of the injury, not cosmetic procedures.
