Why does my jaw pop when I yawn?

On my first year of PT school, I worked at a TMJ or jaw specialty clinic. So, I got to see a ton of jaw patients and I’ll try not to get too technical. If your feel like you’re having pops when you yawn, it means there are two joints with one bone in between and when you open the top of the the mandible or the jaw bone, it glides forward. There’s this little thing called a meniscus or disc on top of the mandible  that is supposed to glide with it as it opens.

What happens sometimes is that it will either slip off the meniscus or, much more commonly, that the meniscus is dislocated forward and so it starts to glide and then pops off before colliding back and recapturing the disk, causing the pop you often hear. That’s usually the pop. Often there’s a pop going out.

All that’s to say, a lot of people have popping jaws and it’s really not an issue. So even if there’s no pain associated with it, you might still want to get it checked out to see if it might become a painful issue. Problems issues when it was painful, especially if you’re having an increase in the amount of popping or pop volume. At that point you’re probably heading towards your jaw getting locked open or closed, which can be quite scary incident.

So if you’re having loud popping and it’s getting worse then definitely get someone to check it out, but that is generally why sometimes your jaw pops when you yawn.
