This habit is called Bruxism
. Habit of grinding teeth or clenching their jaw under stress
. Kindly consult a dentist
in person for further suggestion. We need more investigations with clinical examination to decide upon treatment. A grinding mouthguard can be made. This is like a sports mouthguard, but harder. It will help protect the teeth, muscles and jaw joint from the pressure of clenching and grinding. It will not stop bruxism and in some cases can make the actual grinding worse, but it will lessen the damage to your teeth.
