My dentist told me that when your jaw gets all clicky it’s because of problems with the cartilage between your jaw and your face. Apparently this can become a problem? I have a clicky jaw. Also my dentist is a god amongst men so you should listen to him.
Alternately you could stop opening your mouth so wide all the time. That’s not helping.
The first option is to call the police during one of their fights. This is kind of extreme and also a little awkward if it turns out no one is in any danger. But it is definitely a thing you can do. If you visit Armidale, NSW, you’ll notice a giant road sign on the way into town that encourages this course of action.
