Is it normal to crack your jaw?
Mostly.Normal for most people
Jaw cracking or clicking is common, especially if it doesn’t hurt. Try not to force your jaw to pop; pain, locking, or trouble opening your mouth is worth getting checked.
A painless click or crack when you chew, yawn, or open your mouth happens to lots of people. It can come from the jaw joint and nearby tissues moving, and by itself usually isn’t a problem.
