TMJ or temporalmandibular joint pain can cause tooth grinding. Other causes can be a bad car accident resulting in whiplash, tumors in the skull, orthodontic treatment, arthritis, and even violin playing. But most often it is a vitamin deficiency that is causing bruxism. Taking calcium and pantothenic acid can prevent bruxism. Calcium is used in the muscles to stop involuntary movements.
Pantothenic acid maintains muscle coordination.
Eating sugar within a few hours of sleep can make bruxism worse. Do not eat any sugar within 6 hours before bedtime. Eat a light protein snack instead. Soda and processed foods can deplete the teeth and of calcium and pantothenic acid avoid them. People with bruxism have noticed that the more stress they have the worse it gets.
