Grinding of teeth at night is known as bruxism
. It can occur because of stress
or can occur because of traumatic bite present. It causes soreness of jaw, headaches
, sensitivity of teeth etc. Teeth grinding can cause wearing of the tooth structure which may involve dental pulp and cause soreness of tooth. If dental pulp is also involved due to tooth wearing, then you will require root canal treatment
. You have to visit your dentist
to get your teeth evaluated. Your dentist may take an x-ray to see that whether dental pulp is involved in sore teeth or not. Its better if you get a custom made mouth guard from a dentist than using the mouth guard which you got from pharmacy. Mouth guard should be made according to patient’s teeth and alignment of his teeth. Mouth guard absorbs the chewing forces and prevent damage to teeth and surrounding tissues. Main causes of teeth grinding are stress or traumatic bite. You need to reduce your stress levels. If there is traumatic bite present which is causing teeth grinding, then dentist can correct it. By the time, you visit your dentist you can take OTC pain meds.
