I wear a night guard made by the dentist because I grind my teeth so badly. I find some relief. I can't chew gum because my teeth are so sensitive. I practice deep relaxation before going to sleep and take melatonin to get as quiet and calm a sleep as possible. These seem to be the most successful so far.
The secret of health for both mind and body is not to mourn for the past, not to worry about the future, or not to anticipate troubles, but to live in the present moment wisely and earnestly. Buddha
