Why do People Grind Teeth?

In the oral clinic, many patients saw for bruxism. Night molars are abnormal excitement of some brain cells in the central nervous system cerebral cortex and jaw running area, leading to trigeminal dysfunction, and trigeminal nerves dominate masticatory muscles. Shrinking chewing motion that causes teeth to rattle. Generally divided into 3 types: molar type, bite type and mixed type.

The so-called bruxism refers to those who have habitual molar grinding or unconscious molar grinding habits during sleep, which are aggravated over time, which is a long-term vicious cycle disease.

Molar Introduction

People are in the period of tooth replacement from 6 to 13 years old, and there will be teeth grinding in order to adapt to the upper and lower teeth running-in. However, if adolescents and adults who have passed the period of tooth replacement often have molars, it is a disease.

Molar type

1. Molar type: often molar after falling asleep at night, which is often referred to as nocturnal molars. During sleep, patients perform grinding or clenching teeth. Because teeth are often accompanied by "creak" sounds, they are often called "grit" . It is also known as "night bruxism" because it occurs during sleep at night. Patients are often unaware of it and often told by others. They are valued because they affect others, especially their spouses.

2. Clenching type: often during the day when the concentration is involuntarily clenched teeth, but there is no phenomenon of grinding of upper and lower teeth

3. Mixed type: It has the phenomenon of both night molars and clenched teeth during the day.

Molar hazard

Medical experts point out that: due to the night molars, the teeth are strongly beaten together, and there is no food relaxation, which causes the protective material on the tooth surface to be excessively worn away, exposing the dentin beneath the protective material. The mild person is allergic to cold, hot, sour, sweet and other irritating foods; the severe person can cause frequent gum bleeding, inflammation, loose teeth or even loss of teeth.

The most harmful are the clenched teeth and the night molars. Children's night molars are more common. Although nighttime molars will not feel any pain for a while, it can cause severe wear on the occlusal surface and adjacent surfaces of the teeth over a long period of time, and cause various diseases mentioned above. Refractory bruxism can cause periodontal tissue damage, tooth loosening, or Displacement, withdrawal of gums, loss of alveolar bone. We chew food during the day and rub our teeth, but there is very little damage to the teeth. This is because the food between the upper and lower teeth is a cushion when chewing, and there is sufficient saliva to make the teeth smooth, so it is not easy to wear. It seems to chew for a long time while eating, but most of the time is up and down movement, some people have studied direct tooth contact for only about 4 minutes. If you grind your teeth at night, the situation will be very different. There is no food in your mouth, and the secretion in your mouth is reduced. The teeth do not get the necessary lubrication, and a "dry grind" is formed, just like pushing an empty grinder. In this way, the wear of the teeth is very serious, and the consequences are quite serious. At this time, the worn teeth often have sourness or pain in different procedures, and sometimes cause temporomandibular joint dysfunction, which destroys the morphology of the occlusal system. Features. It can also cause masticatory muscle dysfunction, such as hyperfunction, cramps, fatigue, pain and so on. Unbalanced muscle contraction, abnormal occlusion, changes in the vertical height of the jaw, and imbalance of the position of the disc process also directly affect the normal form and function of the temporomandibular joint, showing symptoms such as pain at the jaw joint, joint popping, and restricted mouth opening. . The pain is oppressive and blunt, especially when you get up in the morning. Nocturnal teethers can affect the sleep of others.

In addition, long-term nocturnal molars may cause a series of complications. Such as: causing the masticatory muscles to not rest, causing fatigue and pain in the chewing muscles, pain in the cheeks; severe headaches, neck and back pain, etc .; it can also lead to reduced sleep quality, memory loss, bad breath or oral odor, and damage to hearing And taste, individual patients with severe molars can cause asymmetry of the face (usually manifested as, one face is large, the other face is small, leading to psychological depression and pessimistic and even terrible consequences. Many severe patients are also accompanied by gastrointestinal disorders, Constipation, decreased sleep quality, fatigue,

The phenomenon of lack of energy and lack of interest in things, especially because of the impact of molars on sleep quality, is easier to get tired from work and study during the day, so we must pay attention to it.

Long-term bruising will cause extensive loss of tooth tissue, damage to the tooth shape, and sharp edges. Often, it can puncture the soft tissues of the lips, cheeks, and tongue. The lower third of the face becomes old and affects the patient's facial appearance and pronunciation. The gums often bleed and become inflamed, causing tooth looseness and tooth loss, allergies, cold and hot acid pain, pain in the cheek and lateral ear area, damage to hearing, soreness and stiffness of the head and neck muscles, leading to recurrent headaches, chewing and chewing. Injury to the gums, biting teeth, and biting the tongue affect the development of adolescents' body parts and mental health. The creak of teething affects the rest of loved ones. In addition, if the child's molars will affect his growth and development, picky eaters, nutritional imbalance, short stature, weight loss, and during the development of the child's teeth, molars will also damage the beauty of the child's teeth, so parents must pay special attention to .

Causes of Molars

(1) Nervousness, psychological anxiety, depression, anger and other psychological factors;

(2) gastrointestinal diseases, endocrine disorders can also cause this;

(3) Excessive fatigue, engaged in delicate workers, such as athletes, watchmakers, etc .;

(4) The lack of trace elements in the body is prone to this disease;

(5) habitual bruxism caused by long-term molar formation;

(6) High work pressure, exhausted body, and irregular life due to long-term life;

(7) Persons infected with ascariasis.

In addition to the above types of people, people who are introverted, emotional, and often get into the habit of biting things in their mouths are also prone to bruxism.

Oral physiology and psychology believe that the oral cavity is the first source of excitement for the human body and a channel for communication with the outside world, and the oral cavity has functions of expressing tension, pessimism and other emotions. Today's people's pace of life is constantly accelerating, and competition is becoming more and more fierce. Everyone tries to dissipate all the pressures in life or work. One of the effective methods is physical exercise and mental transfer, and some people show their teeth.

Some researchers did a controlled study of 80 pairs of molars and non-molars, and made personality measurements for each person. The results show that introverted and depressed personality, especially emotional instability and tension, are important factors in the development of bruxism. In other words, people with bruxism are more pessimistic than those without bruxism. Many scholars have found in research that oral diseases are not important in the cause of bruxism, and psychological factors occupy the first place.

From the perspective of psychoanalysis, molars represent a psychological condition and a frustration and anxiety. It belongs to the subconscious psychological pressure, especially when angry, anxious, resentful, pessimistic and abused. When people escape the subconscious psychological pressure, they will bruise their teeth in dreams or sleep.

Common causes of molar children

1. Intestinal parasitic diseases, especially intestinal roundworm, are quite common in children;

2. Gastrointestinal diseases, oral diseases;

3. Give children indigestible food before going to bed, so that after the baby sleeps, it may stimulate the corresponding part of the brain and cause the masticatory muscles to contract continuously through the nerves;

4. Nervous system diseases, such as psychomotor epilepsy and rickets;

5. Children's emotional factors such as emotional excitement, excessive fatigue or emotional stress during the day.

6. Vitamin deficiency, children with vitamin D deficiency rickets, due to calcium and phosphorus metabolism disorders in the body, can cause decalcification of bones, muscle soreness and autonomic disorders, often sweating, night terrors, irritability and night molars .

7. The teeth are not aligned, the chewing muscle is too strong or chewing on one side of the tooth for a long time, and the occlusal relationship of the teeth is not good. Temporomandibular joint dysfunction occurs, which can also cause nighttime molars. In addition, children with irregularly arranged teeth often have abnormal masticatory muscle positions. When they sleep at night, the masticatory muscles often contract unconsciously, causing molars.

8. In addition, during the child's 8--11 year old tooth replacement period, because the gums are itchy, it is easy to produce slight molars. During this period, mild molars are normal symptoms. If they are more serious, they need treatment. After this stage, usually, Will disappear on its own;

9. The influence of children's emotions and life rules. Nowadays children usually study nervously and under pressure. At the same time, many children watch thrilling fighting TV at night and play excessively before going to bed. These factors can cause teeth grinding. In addition, if a parent is scolded for something for a long time, causing depression, anxiety, and anxiety, the phenomenon of nighttime molars will also occur;

It can be seen that molars are basically caused by a certain disease. Some children have a longer period of molars. Although they have been treated accordingly, because the cerebral cortex has formed a strong conditioned reflex, the molar action at night will not disappear immediately. It is easy to form a habitual molar. Although gastrointestinal disorders have improved, gastrointestinal dysfunction still exists, so the molar action cannot be corrected in a short time, and it must be treated for a long time to improve.

4 Molar molars 4 major adverse effects on baby

Baby occasionally has one or two night molars, which will not affect physical health, and mommy need not worry too much. If the baby grinds his teeth every day, it will cause Mummy's attention, and its adverse effect on the baby is not small.

Molar teeth wear prematurely

Frequent grinding will cause the baby's teeth to wear out prematurely, exposing dentin, causing dentin allergies, and intense pain when cold, hot, sour, sweet and other stimuli occur.

Molars affect baby's face

When grinding the teeth, the facial muscles, especially the chewing muscles, keep shrinking. Over time, the chewing muscle fibers of the baby will thicken, and the face shape will change, affecting the baby's face.

Molar Temporomandibular Disorder Syndrome

If the baby's teeth are severely worn, the height of the teeth is reduced, and the facial muscles are overtired, a temporomandibular joint disorder syndrome will occur. When talking, singing or eating, the baby's jaw joints and local muscles will be sore and even have difficulty opening their mouths.

Molars form strong conditioned reflexes in the cerebral cortex

Some babies have longer molars. Although the cause of molars has been eliminated after treatment, because the cerebral cortex has formed a strong conditioned reflex, the molar action at night will not disappear immediately, and the harm of molars will continue for a long time. .

Molar examination diagnosis

1. Patients have typical actions of grinding or clenching teeth during sleep.

2. Stubborn bruxism can be seen, and the conjunctival and adjacent surfaces are severely worn.

3. Periodontal, alveolar bone, gingival atrophy, tooth loosening, displacement and other changes.

4. Masticatory muscle fatigue, weak bite.

5. Associated with 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.

8. When you have breakfast, you will feel obvious pain in your cheeks.

Molar treatment

There are many ways to treat bruxism. In clinical, the main purpose is to reduce the damage caused by molars to the occlusal surface of the teeth and reduce the symptoms of muscular joints. The principle is to block the cause and reduce damage.

1. Psychotherapy: It does have the effect of psycho-psychological factors, which makes the jaw muscle tension too. Eliminate tension, relieve unnecessary concerns, and arrange work reasonably. If necessary, take diazepam orally, 1-2 times a day, one tablet at a time. There are dependencies.

2. Brain excitement treatment: rest and relax before bedtime, do proper gymnastics, avoid excitatory foods and smoking, and improve the sleeping environment, etc. are helpful to reduce the excitement of the brain. The psychological effects of self-awareness and self-control of patients are mobilized to reduce the occurrence of molars. Little effect.

3. Muscle relaxation therapy: Excessive tension in the jaw muscles is one of the causes of bruxism. Relieving excessive muscle tension during treatment is a necessary means to control bruxism. Commonly used methods are: application of muscle relaxation instrument; physical therapy, physiological function training of chewing muscles; massage; audiovisual cues and other methods. Little effect.

4. Treatment of arousal stimulation during sleep: Through biofeedback, patients are awakened by electrical signals such as sound when molars occur, thereby temporarily stopping molars. Some scholars have temporarily afferent electrical stimulation of the lips, and the results are effective in controlling bruxism. However, this method interferes with the sleep of patients and cohabitants, and the effect is not long-term.

5. Adjusting occlusal treatment: By adjusting and grinding a small amount of dental tissue, removing occlusal interference and early occlusal contact, establishing a occlusal balance relationship to achieve physiological balance between the jaw, chewing muscle, and temporomandibular joint and eliminate bruxism . For patients with occlusal deformities, first perform orthodontics or repair. Then take Mulinting capsules to condition the nerves to eliminate bruxism.

6. Intestinal deworming treatment: Ascaris treatment, reducing intestinal parasites' peristalsis to stimulate the intestinal wall. Nocturnal molars caused by roundworms due to hygiene reasons may occur in childhood, but the chance of nocturnal molars caused by roundworms in adolescence and adults is almost non-existent. Therefore, deworming treatments are not effective for adolescents and adults.

7. Bite plate treatment: make a brace, wear it on the jaw before going to bed at night, and remove it in the morning to ease muscle tension. At present, it is most easily accepted by physicians and patients. The effect of preventing tooth wear is obvious but it cannot treat bruxism.

8. Correct the bad habits of the dental jaw system. Such as chewing unilaterally, biting a pencil, and often chewing gum.

9. Drug therapy: The main focus is to try to adjust the dental and maxillofacial dyskinesias and muscle dystonia.

Topical application of botulinum toxin (BTX) is effective in treating dyskinesias. BTX was injected into the bilateral chewing muscles of perennial molar patients. As a result, most patients started to stop tooth grinding within 4 weeks after injection, but some patients also had difficulty swallowing.

Using L-dopa to regulate the central nervous system can significantly reduce the number of molars of molars, but it is easy to cause nausea, vomiting, insomnia, arrhythmia, and psychotic attacks. It should only be considered if other treatments have not been effective for bruxism.

Patients with severe nocturnal molars need to take active treatment measures, starting with the cause, paying attention to regulating their psychology and reducing stress. It is best to relax before bedtime, avoid excitatory foods, and improve the sleeping environment. Should also actively treat systemic diseases and reduce the incidence of nocturnal molars.

For bruxism, which is dominated by occlusal factors, you need to go to the dental department of the hospital for treatment, and remove the early contact points of the teeth to remove the occlusal interference. Patients with missing teeth do denture repair, change unilateral chewing habits and other measures to achieve occlusal balance.

If the teeth are badly worn, it is recommended to use occlusal pads to prevent them from further wear. Patients can't buy it by themselves, they need to be selected and worn under the guidance of a doctor. The price of occlusal pads is around 1,000 yuan.

10. Chinese medicine diet:

(1) Fresh wolfberry (with stalks in the first pot), half a catty, day lily (20 pieces), candied dates (2 to 3), pig pancreas (1 piece), soup.

(2) Eating a piece of raw orange peel or soaking water in tan peel before going to bed every night for 2-3 days can cure children and adults sleeping molars, which is especially effective for early molars.

(3) Rehmannia glutinosa, two, Zexie, three money, moxibustion and licorice, three money, black plum, three dogwood, four Yuanzhi, three peony skins, four yam, three schisandra, three yuan, fragrant magnet 1 two, (fry first) rush, 2 money, (priming) (fried)

11. For the prevention and treatment of teeth, we must first pay attention not to make the child excessively excited and tired during the day and before going to bed, do not tell horror stories before going to bed, and refrain from reproaching the child to maintain a relaxed and happy mental state and cultivate good sleeping habits. Secondly, the child should be repeatedly checked for intestinal parasites, and if there is, deworming treatment is feasible. And pay attention to adjust the child's diet, eat digestible, light diet for dinner, and should not be full. If you have periodontal inflammation, difficulty in tooth meshing, etc., you can ask your dentist for treatment.

12 · Traditional Chinese medicine believes that most of the teeth are hot in the stomach, which can be treated with acupuncture, acupuncture, acupuncture, massage, etc., or Xuanfengsan can be used to clear away heat and insects: 6 grams of betel nut, 2 grams of tangerine peel and licorice, black ugly (Fried) 12 grams, researched finely, refining honey into pills, 2 grams each time, 2 times a day, warm water to serve.

Molar prevention

Children 8-12 years old can be left untreated and pay attention to rest. In addition, children's molar parents usually pay attention to regulating the children's diet and life, pay attention to calcium and vitamin supplements, eliminate various disease factors that cause molars, and relax at the same time. Daytime Avoid excessive excitement and don't go over the Internet. Relax before going to bed. Don't watch irritating movies or TV. Go to the hospital for a stool test to check for intestinal parasitic diseases (the peristalsis of the parasites stimulates the nerves and causes the reflex effect of the nerves, which causes symptoms. However, the current health and living conditions have been improved, so the parasites cause The chance of this symptom is very low). If there is a worm, drive it under the guidance of a doctor. Dental refractory cases should be made into dental jaw pads and worn before bedtime. It can temporarily relieve symptoms and prevent direct tooth wear, but ca nt take roots. At the same time, you should relax as much as possible, pay attention to light and nutritious diet, do nt eat too many things when you sleep, and you must reduce the number of friends who smoke and drink. Meals are normal and life is regular, which can help to regulate well;

1. Try to relax yourself before going to bed, especially before falling asleep. Can do some gymnastics, hot water bath, listen to light music and so on.

2. Avoid excitatory foods and smoking, and improve the sleeping environment.

3. Try to avoid drinks or foods containing caffeine. Try to avoid coffee, chocolate, cola, etc.

4, eat more foods rich in vitamins.

5. Know how to relieve stress, relax and adjust your mindset.

6, hot compress the upper and lower jaw, can relax and bite the muscles, can also reduce the chance of headache

7, maintain the correct posture. Bent hump can also lead to molars.

8. Be sure to brush your teeth before going to bed.

9, pay attention to calcium supplement in daily diet, deworming regularly;

10. Keep your mouth in a healthy resting state during the day, that is, keep your teeth relaxed;

11. Watch less irritating TV shows before bedtime and try to relax your mind.

12. Avoid excessive excitement during the day.

Molar new discovery

The brain and digestive system-related organs such as the stomach, salivary glands, and masticatory muscles are closely linked and affect each other. The direct cause of molars is dysfunction of autonomic nerves, abnormal excitement of the trigeminal motor branch that governs the masticatory muscles, or abnormal digestive system signals to the brain that the brain mistakenly believes that it needs to eat and starts masticatory muscle movement. Molars occur when you close them. The pathological basis is abnormal excitement of the cerebral cortex, disturbance of intestinal-brain interactions, and dysfunction of the gastrointestinal tract that cause molars. In the past, there was a saying that a worm in the stomach caused molars. This is actually a misunderstanding. It is not the intestinal parasites that cause molars, but the abnormal intestinal stimulation of the brain that causes molars. At the same time, mental stress or unsatisfactory mental state or mental stress also cause molars. There is an idiom called "gritting teeth", which is actually an involuntary gnashing action caused by mental stress. The mental stress in sleep also causes " Squeezing the teeth , in short, molars are closely related to the mental state of the person.
