Can chewing gum be dangerous?

How often do you chew gum? Do you chew just to freshen your breath or as a way to relieve stress? I bet it does relax you at least a little, whether you realize it or not, because that's part of the appeal of gum versus breath mints. But chewing gum can cause problems if you overdo it (like anything) especially if you're feeling tense to begin with. According to the University of Texas Southwestern Medical Center in Dallas, chewing gum when you're stressed can cause you to chew more vigorously, which can lead to any number of problems like a strained jaw, fatigue, soreness, and even a serious condition of the jaw joint called TMJ.

Huh, who knew?
