Hi! Welcome to Healthcaremagic. I read your query. Bruxism can be due to stess, anxiety or local oral factors like abnormal bite, missing or malalligned teeth etc. Since you are already getting orthodontic treatment with braces, bite plate will help in correction of deep bite if you have. Also it prevents direct trauma to TMJ by distributing grinding force on teeth. In addition to this, avoid stress. Do calming exerciss, meditation. Drink lots of water and avoid alcohol, caffeine, chocolate. Relax your oral muscles by exercise. Put a warm cloth in front of your earlobe for 5 min. This also relaxes oral muscles. Avoid chewing gums and intentional clenching. Hope the answer helps. Thank you.
