Stress reduction. First, a mouth guards does not cure clenching. It merely protects your teeth from the wear and tear that clenching produces. Reduction of stress can sometimes be reduced with relaxing techniques such as yoga, exercise, a walk outside in the fresh air, deep breathing exercises, a warm bath or with any hobby or other activity that you enjoy and gets your mind off the stresses of daily life.

Yes. There are numerous treatments available such as exercises, compresses, medications, behavior modification, etc., all designed to mask symptoms. Better solution would be to determine the reason you clench and treat the cause. With that in mind a custom occlusal orthotic (night guard) is the most effective symptom crutch. See your Dentist for help.
