How do healthy teenagers grind their teeth when they sleep at night?

Molar is caused by repeated contraction of masticatory muscles and collision of upper and lower teeth. The contraction of masticatory muscles is controlled by trigeminal nerve. When the trigeminal nerve is excited, it will lead to the contraction of masticatory muscles and the phenomenon of grinding teeth. Bruxism is a phenomenon that people are unconscious when they sleep or wake up under non-physiological functions, which leads to the grinding or clenching of upper and lower teeth. The most serious harm is nocturnal grinding and nocturnal grinding. Because grinding teeth is often accompanied by the sound of "creaking", it is usually also called "grinding teeth". It also happens at night, so it is also called "sleeping grinding teeth". Night molars can be divided into persistent night molars and intermittent night molars, most of which are intermittent night molars. Etiological pathologists from 6 years old to 13 years old are all changing teeth, and there will be molars to adapt to the running-in of upper and lower teeth. When the upper and lower teeth just erupt, the occlusal position of the teeth has not been completely determined, and there will be some discomfort between the teeth, such as unevenness or too sharp new teeth. At this time, the inappropriate part can be ground off by grinding the teeth. Therefore, for children in the period of eruption of primary teeth and replacement of primary and permanent teeth, night grinding is an activity that is establishing a normal chewing relationship and belongs to a normal physiological phenomenon. However, it is morbid for teenagers and adults who have passed the tooth-changing period to grind their teeth frequently. There are several reasons for this symptom: first, mental factors, emotional tension is the most common pathogenic factor of bruxism. When fear, anger, conflict, and emotional depression are difficult to vent, these emotions are hidden in the subconscious, and they are periodically expressed by gnashing their teeth. It is observed that bruxism is a common phenomenon among mental patients. When you want to escape from subconscious psychological pressure, you are likely to grind your teeth during sleep. Many scholars' investigation and analysis results also prove that bruxism patients are more pessimistic than non-bruxism patients. Of course, not everyone will gnash their teeth in the above situation. There are also individual differences. Let's just say that when you gnash your teeth, you should look for reasons in this respect. For example, excessive excitement, tension, anger and nerve stimulation during the day make people grind their teeth when they sleep at night. If the child is too excited during the day, or too tired during the day, and too busy and tired before going to bed at night, although most of the cerebral cortex is inhibited after falling asleep, some areas (such as the trigeminal nerve of the pons) will still be excited. This will send a "signal" to command the facial masticatory muscles to contract for a short time. Therefore, the sleeping person will involuntarily move his teeth up and down, left and right, and then make a "squeaky" grinding sound. Second, there are parasites or other reasons in the intestine. When people fall asleep at night, parasites creep in the intestinal cavity, which stimulates the nerves to some extent and causes nerve reflex. Ascaris lumbricoides can secrete many toxins, such as neurotoxins, allergic toxins, hemolytic toxins and enzymatic toxins. In addition, some metabolites excreted by worms will constantly stimulate the corresponding parts of the sleeping human brain, so that some people's masticatory muscles will continue to contract at night, leading to molars. But not all patients with parasitic diseases grind their teeth at night. Some people usually eat irregularly, which leads to gastrointestinal diseases, endocrine disorders and bruxism. In addition, some people sometimes eat too much at night, and when they fall asleep, a lot of food accumulates in their intestines, so the gastrointestinal tract has to work overtime. Because of the heavy burden, they will unconsciously grind their teeth when they sleep. Children's nutritional deficiency, blood sugar and calcium concentration, endocrine disorder and allergic reaction may all become the pathogenic factors of bruxism, and some cases are genetic factors. In addition, hyperuricemia, hyperthyroidism, allergy and bladder stress may all be related to bruxism. Third, abnormal tooth contact, tooth and dentition diseases. Dental caries can not be treated in time, and then pulpitis and periapical periodontitis will occur, causing pain, abscess and even premature loss of deciduous teeth, which will lead to unilateral chewing habits. Long-term unilateral chewing will lead to uneven occlusion, occlusal disorder, resulting in persistent night molars, as well as irregular dentition, such as crowded teeth, crossbite, open occlusion and so on. , will lead to occlusal disharmony, which will cause night molars. If there is premature contact occlusion, patients often try to smooth the high point of this tooth surface. If this phenomenon occurs frequently, bruxism will form over time. Bruxism, due to the long contact time between the upper and lower teeth and the great stress, often leads to excessive wear of the whole mouth teeth, especially the front teeth, causing tooth allergy and pulp disease, or occlusal trauma causing tooth loosening and food impaction. In addition, occlusal type, tooth position, tooth looseness, mandibular movement, tooth type and restoration are related to bruxism. Fourth, fatigue and professional factors, such as seiko, athletes, IT workers, writers, clockmakers, designers, etc., are prone to bruxism, which is also related to nervous tension; Fifth, people who lack vitamins and trace elements in the body are prone to bruxism. For example, a considerable number of children grind their teeth at night because of partial eclipse and picky eaters, resulting in unbalanced nutrition; Thirdly, the central nervous system of molars is out of control for a long time, which becomes habitual bruxism: molars, like sleepwalking, enuresis and nightmares, are an unconscious subconscious action, a symptom of partial awakening of the brain during sleep, and a reaction of out-of-control regulation of the higher central nervous system. Because the activity of cerebral cortex is controlled, the subconscious jaw-closing reflex increases, and the rhythm of muscle tension and contraction changes obviously, resulting in fist-clenching and grinding; After waking up, the molars are controlled. The most fundamental reason for most long-term molar patients is related to this. Molting becomes a conditioned reflex behavior during sleep. In addition, people who are introverted, emotional and often bite their mouths are also prone to bruxism. At the same time, lateral position and abdominal sleep during sleep are also prone to bruxism. These postures make the stress on the mandible uneven, the joint position changes, and the teeth form interference contact, which leads to the increase of mandibular muscle tension, which is manifested as grinding teeth or grinding teeth. Editing this paragraph hurts molars, causing teeth to collide strongly. Without food relief, the secretion of saliva is correspondingly reduced, and the teeth are not lubricated, resulting in excessive wear of the protective substance on the tooth surface and exposure of dentin under the protective substance. Each tooth is divided into three parts: the root growing in the alveolar cavity, the crown exposed outside, and the neck between the root and the crown. Teeth are mainly composed of dentin, and the outer layer of dentin in the crown has ivory hard enamel. The cavity in the center of the tooth is the pulp cavity, which is filled with pulp and rich in blood vessels and nerves. Brushing your teeth at night and direct contact between the upper and lower teeth is not only powerful, but also lasts for a long time, causing enamel wear, allergic to cold, hot, sour, sweet and other irritating foods, affecting the appearance of teeth; In severe cases, it will lead to frequent bleeding, inflammation, tooth loosening and even falling off. In addition, grinding teeth for a long time 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. Teenage molars will not only cause dentofacial deformities, but also affect physical development and even lead to psychological disorders such as autism. In addition, grinding teeth will also affect the sleep quality of relatives and themselves, make patients nervous, and even lead to terrible consequences such as psychological depression and suicide. Once a person suffers from night grinding, it is equivalent to suffering from a vicious circle of disease. When people want to escape the psychological pressure of the subconscious, they are likely to grind their teeth during sleep. Night molars can cause insomnia, neurasthenia, endocrine disorders and other symptoms. 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. Among the common bruxism, night molars and night molars are the most serious. 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, the change of vertical height between jaws and the imbalance of disc process position also directly affect the normal shape and function of temporomandibular joint, which is manifested as joint pain, 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. It can be seen that the problem of grinding teeth can not be ignored. To eliminate bruxism, first of all, patients should try their best to relieve tension and unpleasant emotions; The second is to go to the hospital for treatment. Bruxism can be cured after a period of treatment. Edit this diagnosis 1. Patients typically grind their teeth or clench their teeth during sleep. 2. It can be seen that the occlusal surface and adjacent surface of patients with intractable bruxism are seriously worn. 3. Periodontal, alveolar bone, gingival atrophy, tooth loosening, displacement and other changes. 4. Fatigue of masticatory muscles and weakness of occlusion. 5. There are symptoms of temporomandibular joint dysfunction. 6. After getting up, the patient has symptoms of head and neck pain. 7. More common in children and adolescent male patients. [1] Edit the processing method of this paragraph. For difficult cases, a mandibular pad should be made and worn 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. Specific treatment: (1) Psychotherapy: Bruxism patients do have the effect of mental and psychological factors, which make the mandibular muscles overstretch. Such as emotional tension, anxiety, anxiety or fear of bruxism. With such symptoms, it is important to relieve their ideological concerns and establish confidence in treating diseases. Eliminate nervousness, relieve unnecessary worries, be open-minded, arrange work reasonably, and take diazepam orally if necessary, 1-2 times, one tablet each time. There is also a need to develop good living habits, live regularly, don't eat too much for dinner, and don't do strenuous exercise before going to bed, especially for children. (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. When treating ascaris lumbricoides in children with traditional Chinese medicine, after the toxin produced by ascaris lumbricoides and its metabolites are absorbed by the human body, some neurological symptoms will appear, 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. Give you a good prescription: Radix Rehmanniae 1, Rhizoma Alismatis 3, Qianling Magnet 1, Radix Glycyrrhizae Moxibustion 3, Mume 3, Fructus Schisandrae 3, Rhizoma Cyperi 5, Cornus officinalis 4, Radix Polygalae 3, Cortex Moutan 3, Rhizoma Dioscoreae 4, Juncus Junci 2, and prevention and treatment of the above seven drugs (decocted first). 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. When the symptoms are mild, do not deal with them, and 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. Correct the bad habits of the oral system, such as unilateral chewing and biting pencils. If the above treatment still does not improve, we should make an dentition pad in the stomatological hospital, put it on the dentition before going to bed at night and take it off in the morning. Pad can eliminate interference and relieve muscle tension. 1. Keep your oral health at rest during the day, that is, keep your teeth loose, preferably with your lips together and your teeth apart. Biting apples or raw radishes will make your upper and lower jaws tired, which can calm your mouth. 3. Hot compress on your upper and lower jaws can relax your 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. 5. Grinding teeth has the greatest relationship with stress. So relaxing is the best way. 6. Reduce the intake of caffeine and refined carbohydrates. 7. Take a hot bath and entertain yourself. 8. Learn relaxation methods, such as meditation or gradual relaxation.
