The night is still young, and most are fast asleep, yet some individuals (especially children) grind their teeth during deep slumber. Since no food is present to cushion the mouth during nighttime grinding, saliva secretion decreases, leaving teeth inadequately lubricated. This dry grinding causes significant damage to teeth. So, what are the causes and prevention methods for sleep-related teeth grinding?
I. What Causes Sleep Bruxism?
1. What causes sleep bruxism? The grinding motion is triggered by sustained contraction of the chewing muscles. The masseter muscle is primarily controlled by motor nerves. Why these nerves become so active at night—when the body neither eats nor drinks—compelling the chewing muscles to contract continuously remains unclear.However, clinically, cases of teeth grinding caused by ascariasis and gastrointestinal dysfunction are frequently observed. What causes teeth grinding during sleep? Intestinal parasites are a major factor.
2. Of course, nighttime teeth grinding may also stem from other causes. For instance, children who play vigorously during the day, or adults whose work is highly stressful and who remain busy right before bedtime.Even after falling asleep, if parts of the cerebral cortex remain in an excited state, nighttime teeth grinding can occur. 3. Our bodies host many parasites, some beneficial and some harmful. Among the harmful ones, the most notorious is probably the roundworm.What causes teeth grinding during sleep? As children, we heard parents say it was due to roundworms coming out to feed. This explanation still holds some truth today.
Many parasites secrete toxins like neurotoxins and allergenic toxins. Additionally, the metabolic waste they expel from the body, along with various toxins, continuously stimulates corresponding areas of the human brain. This stimulation then triggers teeth grinding during sleep.
II. How to Prevent Sleep Bruxism
Sleep bruxism is a phenomenon akin to talking in one's sleep or nocturnal emissions. However, prolonged grinding can cause significant dental damage. So how can we prevent it?
1. Relieve tension before bed. Keep an open mind—nothing is insurmountable. If you can't afford a house or find a spouse, remember others face similar struggles.
2. Seek timely treatment for intestinal disorders. If bruxism stems from roundworms, medical intervention is essential.
3. Address various intestinal diseases promptly. If roundworms cause the grinding, seek professional care immediately.
4. Maintain a balanced diet and regular bowel movements. Avoid excessive intake of spicy, greasy, or cold foods.
2. Treat intestinal disorders promptly. If tooth grinding stems from roundworms, seek medical attention immediately.
3. Cultivate healthy habits. Why do people grind teeth at night? Many children eat heavily before bed or have picky eating habits, both of which can trigger nocturnal grinding.
