1. Mental factors The oral cavity has the function of expressing tension. Patients with fear, anger, hostility, conflict and other emotions, especially anxious patients, try to relieve their inner depression by grinding their teeth for some reason. These patients have frequent contact with teeth for a long time. These psychological factors may be one of the important causes of bruxism. 2. Occlusal factors In neurotic individuals, any occlusion interference may be the trigger of bruxism; The occlusal factors of bruxism patients are mostly the mismatch between the median relationship and the median occlusion, and the premature contact of the non-working side during lateral occlusion; Moreover, the clinical occlusal adjustment method has successfully cured some bruxism. Occlusal factor is an important factor of oral health, but whether it causes bruxism is still controversial. When changing teeth, the jaw-biting relationship is disordered, which leads to the movement disorder and spasm and contraction of the progenitor muscles; 3. Central Nervous Mechanism At present, there is a tendency to think that grinding teeth, like sleepwalking, enuresis and nightmares, is an involuntary subconscious action, a symptom of partial awakening of the brain during sleep, a central sleep disorder related to daytime emotions, and is caused by internal or external, psychological or physiological sleep interference stimulation. 4. Other systemic factors, such as gastrointestinal dysfunction related to parasites, nutritional deficiency in children, blood sugar and calcium concentration, endocrine disorders, allergic reactions, etc., may become the pathogenic factors of bruxism. Some cases have genetic factors. In addition, hyperuricemia, hyperthyroidism, allergy and bladder stress may all be related to bruxism. 5. Professional factors, such as drivers and athletes, and jobs that require high precision, such as clockmakers, are easy to be worn out.
The most serious harm is to grit your teeth and grind your teeth at night. Nocturnal molars are more common in children. Although there is no pain in grinding teeth at night for the time being, it will cause serious wear and tear on the occlusal surface and adjacent surface of teeth after a long time, and all kinds of diseases mentioned above will be very complicated. Refractory bruxism can lead to periodontal tissue destruction, tooth loosening or displacement, gingival recession and alveolar bone loss. During the day, when we chew food, we also rub our teeth, but the damage to our teeth is very small. This is because when we chew, the food between our upper and lower teeth is like a cushion, and there is enough saliva to make our teeth smooth, so it is not easy to wear. It seems that I chewed for a long time while eating, but I moved up and down most of the time. Some people have studied that the real direct contact between teeth is only about 4 minutes. If you grind your teeth at night, the situation will be very different. There is no food in the mouth, and the secretion in the mouth is also reduced. Your teeth don't get the necessary lubrication, so they form a "dry grinding". It's really like pushing an empty grinder This kind of tooth wear is very serious, and the consequences are quite serious. At this time, the worn teeth often have different procedures of acidity or pain, and sometimes cause temporomandibular joint dysfunction, destroying the shape and function of the occlusal system. It can also cause masticatory muscle dysfunction, such as masticatory muscle hyperactivity, spasm, fatigue and pain. Unbalanced muscle contraction, abnormal occlusion, change of vertical height between jaws and imbalance of disc process position also directly affect the normal shape and function of temporomandibular joint, which is manifested as pain at the joint, joint snapping and limited mouth opening. Pain is depressing and depressing, especially when you get up in the morning. People who grind their teeth at night will affect others' sleep.
Prevention and control; Don't do it when it's lighter. Pay attention to rest. Psychotherapy can remove pathogenic factors, adjust occlusion and treat systemic diseases related to bruxism. Avoid excessive excitement during the day. Relax before going to bed and don't watch exciting TV movies. Go to the hospital to check intestinal parasitic diseases (parasitic peristalsis stimulates nerves, causes nerve reflex and grinds teeth), and expel worms under the guidance of doctors. Stubborn cases should be made into mandibular pads and put on before going to bed. Can prevent teeth from being directly worn. This will not only make it possible not to grind your teeth at night, but also get a better rest, which is good for work, study and health.
Bruxism is mainly manifested in my inability to control my grinding and grinding activities. Due to long-term continuous grinding, teeth wear is serious, periodontal tissue is damaged, and all components of the entire oral and maxillofacial system are damaged. The principle of treatment is to block the cause and reduce the damage. The first is symptomatic and comprehensive treatment of the cause. Clinically, first relieve jaw muscle spasm, block occlusal interference, eliminate or alleviate bruxism, and then carry out other treatments.
(1) Psychotherapy: Bruxism patients do have the effect of psychological factors, which make the mandibular muscles overstretch. Such as emotional tension, anxiety, anxiety or fear of bruxism. It is very important to comfort and enlighten these patients and relieve their ideological concerns for establishing confidence in treating diseases.
(2) Muscle relaxation therapy: excessive mandibular muscle tension is one of the causes of bruxism, and relieving excessive muscle tension during treatment is a necessary means to control bruxism. The commonly used methods are: using muscle relaxation instrument; Physical therapy, training the physiological function of masticatory muscles; Massage; Audio-visual suggestion and other methods.
(3) Application of bite plate.
(4) occlusal adjustment therapy: through adjusting and polishing a small amount of tooth tissue, the occlusal interference and early occlusal contact can be relieved, and the occlusal balance relationship of natural teeth can be established, so as to achieve the physiological balance among occlusion, masticatory muscles and temporomandibular joint and eliminate bruxism.
(5) Bruxism can also be treated symptomatically, and patients with malocclusion should be treated with orthodontics first. Some need to repair or treat periodontal tissue diseases.
Sleep molars, or molars, refer to the rhythmic contraction of masticatory muscles during sleep, and the upper and lower teeth tightly bite and slide, making a loud creaking sound. People won't wake up at this time. Even if they wake up, they don't know their teeth. Only roommates know.
Sleep molars generally occur in the shallow sleep stage (the second stage). Molar won't appear in dreams. At this time, only physical activity and heart rate increase. When I wake up the next day, I often feel cheek pain and headache, sometimes accompanied by periodontal tissue damage.
The incidence of sleeping molars in children and adolescents is high, which can reach about 15% according to medical statistics. With the growth of age and the gradual improvement of brain function, its attack rate will decrease year by year and heal itself when it grows up.
However, if a child suffers from ascariasis, some neurological symptoms will appear after the toxins and metabolites produced by ascariasis are absorbed by the human body, and grinding teeth is one of the symptoms. Therefore, if a child is found to have ascariasis, it is necessary to use drugs to repel intestinal worms, such as Clivia, Melia azedarach root bark, betel nut and other traditional Chinese medicines have the best insecticidal effect.
Traditional Chinese medicine believes that the brain is the house of Yuan God, and all spirits are integrated. Sleep is related to the movement of yin and yang. If you sleep well, but you have abnormal behavior (including grinding your teeth) during sleep, it is all related to the role of the brain. It is advisable to tonify the kidney and marrow, strengthen the brain and soothe the nerves.
Don't do it when it's lighter. Pay attention to rest. Psychotherapy can remove pathogenic factors, adjust occlusion and treat systemic diseases related to bruxism.

1. Keep your oral health at rest during the day, that is, let.
Keep your teeth relaxed, preferably with your lips together and your teeth apart.
2. Biting apples or raw radishes will make the upper and lower jaws tired and can calm down.

3. Hot compress on the upper and lower jaws can relax the occlusal muscles and reduce the chance of headache.
4. You can buy a mouthguard in a sporting goods store, which helps to prevent grinding your teeth at night.
Grinding teeth has the greatest relationship with stress, so relaxing is the best way.
6. Reduce the intake of caffeine and refined carbohydrates.
