A night guard is a protective barrier that you insert between your jaws, to stop them from grinding together while you sleep.

Manage your stress and anxiety

Speak to your medical practitioner about stress management options. Some ideas include psychotherapy, starting a regular exercise program, and considering muscle relaxants to help you unwind for bedtime.


Make positive lifestyle changes

Notice if you clench your jaw during the day and make a conscious effort to release the tension. Don’t allow yourself to chew on the end of a pencil or on your nails during the daytime. Stop chewing gum to train your jaw muscles out of clenching on a regular basis.


Eliminate or reduce foods and drinks containing caffeine, especially after midday

Eliminate or reduce your alcohol intake, as alcohol has been found to encourage bruxism.

Make a conscious effort to relax and unwind at the end of the day. Play soothing music, take a cool shower or bath, or hold a warm cloth on your jaw muscles to help yourself relax.


Reconsider your medication

If you are taking chronic medication, you should have it reviewed in case it is contributing to your grinding.
