I have TMJ.
I started seeing a specialist for it this summer and they told me I couldn't chew gum because of the way it makes my jaw move in the wrong ways and is making the tissue worse and more non-existent than it already is.
And I've been good, but broke down today. I only chewed on it for about an hour and was careful to not go crazy.
Sucks tho...carrots and celery are hard to eat too![]()
