Axl Rose told the audience at Guns N’ Roses’ MetLife Stadium concert that he is dealing with TMJ-related jaw problems and recent dental treatment. The singer used humour to describe numbness and worrying noises while performing, highlighting how the condition can complicate singing during a demanding live show.

Rose said one side of his mouth remained numb and that he had work done on the other side two days earlier. TMJ affects the jaw joint and can cause pain and popping; despite the issue, Guns N’ Roses played a three-hour set on their 2026 World Tour, with Public Enemy opening.
