I'm wondering what does a dislocated jaw feel like?

Stuck! Ouch!: If dislocated, the condyle ("ball") has slipped beyond the eminence ("socket") and gotten stuck on the front side so that the teeth can't meet. Don't push it! instead, place both thumbs under the chin, grab the lower teeth with the fingers on both sides and rotate the jaw by pulling up on the chin while pushing down on the teeth. The jaw should slip back into place. If not, call the dentist.

Jaw won't closed: Your jaw is locked open, you can not close it, and your bite is off. Very painful. See oral surgeon for treatment.

See an OMS: A dislocated jaw may be caused by forceful yawning or by an impact or trauma and joint hypermobility syndrome. Occasionally, a dislocated jaw can result in bleeding or difficulty breathing and must be treated in an emergency setting by oral surgeon. Do not delay.
