Well, it does for me. My TMJ is horrible, it makes the crepitus sound and pops out if I open it too wide. A mouthguard has helped, maybe it's just a certain one? I will share the one I use, one second .. I think it is this one. It might prevent it in me because I have to bite down to hold it in place? https://a.co/d/0ilYPME6 There might be others that work for you, maybe one that is only one piece so it prevents mouth opening? You could also try a chin strap, like this one: https://a.co/d/07NTp1Y2 I bought one of those, too. Was quite uncomfortable and the night guard worked better (for me).
