Why do we grind our teeth?

Someone makes the sound of grinding teeth while sleeping at night. When he gets up in the morning, he doesn’t know if he asks. Medically called molars or bruxism.

The main causes of teeth grinding at night are:

Excessive emotional stress, excitement, fatigue, fright and other mental factors cause the excitement or inhibition process of the cerebral cortex to become abnormal, causing teeth grinding at night. .

Due to overeating, overeating, and indigestion, the toxins secreted by bacteria in the gastrointestinal tract are absorbed and stimulate the cerebral cortex, causing the excitement and inhibition of the cerebral cortex to lose balance, causing night grinding.

More people, especially children, cause night bruxism due to intestinal parasites. The activity of intestinal parasites and the toxins they secrete stimulate the cerebral cortex to cause spasm and contraction of masticatory muscles, causing night bruxism.

Severe bruxism is dry grinding of the upper and lower teeth, which will accelerate tooth wear, cause periodontal tissue damage, masticatory muscle fatigue and temporomandibular joint dysfunction, so it should be actively prevented and treated.

●Eliminate tension, relieve unnecessary worries, be open-minded, and arrange work reasonably. When necessary, take a small amount of stabilizing drugs under the guidance of a doctor.

●Develop good living habits, have a regular daily routine, don’t eat too much at dinner, and don’t do strenuous exercise before going to bed.

●Treat intestinal parasites and reduce the stimulation of the intestinal wall by the peristalsis of intestinal parasites, which can reflexively cause teeth grinding at night.

●Wear dental braces. If the above treatment still does not improve, you should see a dentist to make a night grinding appliance, also called a jaw pad or a dental pad. Wear it on your teeth at night and remove it in the morning. Teeth pads can separate the upper and lower teeth from direct contact, reduce tooth wear and periodontal damage, and relieve muscle fatigue. At the same time, the signal transmitted from the periodontal ligament to the central nervous system is changed, so that the night grinding activity is inhibited. Practice has proven that the number and time of night grinding are significantly reduced after wearing braces.
