If your candy is crunchy and kind of hard, it can also affect TMJ symptoms. For example, try to avoid Peanut M&Ms, Crunch Bars, Nerds, Peanut Brittle, Almond Joy, Whoppers, and more. Crunchy is a double whammy. Not only do you have to chew longer but you also have to bite harder. The combination of the two is just as bad, if not worse than chewy or hard candies alone.
