Then how did this "squeaking" sound come from? This is the sound of grinding teeth. This state of grinding teeth at night is called bruxism. Bruxism refers to the behavior that people unconsciously rub or grit their teeth when they sleep at night, so why do they grind their teeth when they sleep? What is the reason for sleeping and grinding teeth?

The habit of sleeping and grinding teeth will not only affect the beauty of teeth, but also bring a little influence to people on the body, damage gums and even lead to tooth loss.

First, the reasons for grinding teeth at night

1, high spirits

It leads to imbalance between the excitement and inhibition of cerebral cortex, induces temporary irregular spasm or contraction of masticatory muscles, and produces night molars. Psychological factors such as work pressure, tension, psychological anxiety, depression, irritability, etc.

2. parasites

Intestinal parasitic diseases can also cause molars. You'd better check your stomach for bugs during the day. Adults will.

3, excessive food

Eating too much before going to bed makes the digestive function disorder, excites the brain cells that manage digestion, and causes grinding teeth through reflection.

4. Unbalanced nutrition

In particular, people with unbalanced nutrition and picky eaters are prone to lack of calcium, phosphorus and other elements, causing teeth to grind back and forth, and lack of trace elements in the body, which is prone to this disease.

5. Sleep time

It is best to rest on time at night, eliminate tension and release stress reasonably. Please don't take sleeping pills at will if it is not necessary.

6, the stomach is not good, endocrine disorders can also lead to this.

7, long-term irregular life, excessive fatigue, engaged in fine work, such as athletes, clockmakers, etc.

8. Habitual molars formed by long-term molars.

In addition, people who are introverted, emotional and often bite in their mouths are also prone to grind their teeth. According to oral physiology and psychology, the oral cavity is the first source of human excitement and a channel to communicate with the outside world. The oral cavity has the function of expressing tension and pessimism.

It is found that oral diseases are not important in the pathogenesis of molars, and psychological factors occupy the primary position. Psychologically speaking, grinding teeth represents a psychological state, a sense of frustration and anxiety. Psychological stress belongs to the subconscious, especially when angry, anxious, resentful, pessimistic and abused. When people escape the psychological pressure of the subconscious, they grind their teeth in their dreams or sleep.

Second, the types of molars.

1, molar type: often after falling asleep at night, which is often called night molar, patients grind their teeth or grind their teeth during sleep.

2, bite type: I often bite my teeth unconsciously when I concentrate during the day, but there is no phenomenon of upper and lower teeth grinding.

3, mixed type: both night grinding and daytime biting.

Third, how to prevent molars

8 ~ 12-year-old children need not be treated when their molar symptoms are mild, and should rest. Parents should pay attention to regulating their children's diet and life rules:

1, relieve stress, relax mood and adjust mentality. Avoid excessive excitement during the day, watch less exciting TV dramas before going to bed, and try to relax yourself, especially before going to bed. You can do gymnastics, take a hot bath, listen to light music and so on.

2. Avoid irritating food and smoking (such as caffeinated drinks or foods, such as coffee, chocolate and cola). ) and improve the sleeping environment.

3. Pay attention to calcium supplementation in daily diet and eat more foods rich in vitamins. Regular deworming.

4, hot compress on the upper and lower jaws can relax the occlusal muscles and reduce the chance of headache.

5. Keep the right posture. Humpback can also cause molars.

6. Be sure to brush your teeth before going to bed, and don't be too full for dinner.

7. Maintain a healthy oral rest during the day, that is, keep your teeth loose.

8. Know how to decompress, relax and adjust your mind.

Occasionally grinding your teeth has little effect on your body, but grinding your teeth for a long time, or grinding your teeth for too long after each sleep, will lead to psychological and physical obstacles. Because when grinding teeth at night, there is no food in the mouth, the saliva secretion is correspondingly reduced, and the teeth are not lubricated, thus forming a "dry molar" like a hollow molar.

In addition, long-term bruxism will also cause a series of complications. For example, long-term grinding of teeth causes masticatory muscles to get no rest, which leads to fatigue and pain of masticatory muscles and cheek pain; In severe cases, it can cause headache, neck and back pain, etc. It can also lead to decreased sleep quality, memory loss, bad breath or bad breath, impaired hearing and taste, leading to psychological depression, pessimism and even suicide.

Patients with severe molars should take active treatment measures to reduce the occurrence of night molars.

Patients who have the habit of grinding their teeth can eat more foods rich in vitamins. In daily life, we should pay attention to supplementing calcium to the body and maintaining a correct standing posture, because hunchback can also lead to grinding teeth. Relieving stress can also help solve the problem of grinding teeth.
