Your dentist can advise if you are grinding your teeth at night. Many people grind their teeth and have no idea. The dentist can detect wear and tear.
This grinding can cause people to have jaw aches, headaches, neck aches or many times just have sore teeth and gums making them sensitive to everything you eat or drink.
Having a mouth guard can eliminate this problem for some people. Get a mouth guard made especially to fit your teeth and mouth, so when you grind your teeth there is a cushioning to reduce the impact. With a guard especially fitted, it is extremely comfortable and will enhance your quality of sleep.
There can be a problem of too much anxiety causing poor quality sleep and grinding. Take magnesium supplements, relaxing teas, take herbal supplement like blue vervain, passiflower and have a bath with lavender essential oil to help you relax.
