Another thing that often helps is cutting down on caffeine and alcohol, especially in the evening.
If that doesn’t work, reach for an apple. Munching on crisp fruit or raw veggies can help calm an overactive jaw. But gum is not a good idea – the repeated chomping can compress and irritate the disc between the lower jaw and skull.
Also, try to keep your mouth in a resting position. Your upper and lower teeth should touch only when you swallow or chew. Make it a habit throughout the day and you just might escape the nightly grind.
