You will be dizzy or your balance will be off as the jaw joint is so close to the ear. The ear controls your balance. If you have swelling or inflamation around the jaw joints you will be dizzy.
If you have muscle spasms or tightness around the jaw joints which are near the ears, you will be dizzy.
If you have muscle spasms and tightness at the back of your head which is the sternocleidomastoid muscle, you will be dizzy.
When your jaw is out of alignment, you will be dizzy as there is no harmony with the ears and jaw.
It's that simple.
