The 64-year-old Guns N' Roses frontman told the crowd he’s been dealing with TMJ and underwent a corrective procedure earlier in the week. He described ongoing numbness on the left side of his mouth and called the situation challenging as he performs.
Rose referenced the jaw disorder that can affect the joint and muscles involved in jaw movement. Medical sources note TMJ can cause pain and limit how the jaw functions—details Rose used to explain why singing feels different now.
