Teeth grinding while sleeping is not only uncomfortable for the person sleeping next to it, but it is also a manifestation of a number of diseases, which can even lead to sleep apnea. So what causes teeth grinding while sleeping?
1. What is teeth grinding while sleeping?
Teeth grinding is an activity that can potentially overload the chewing system. Currently, the main cause of the disease is still unknown. However, the disease is often accompanied by stress, occlusal disorders, allergies and related to sleeping positions. Unfortunately, there is currently little data on the causes and effects of the disease. Therefore, careful assessment and treatment is the best way to make the right indications.Bruxism is defined as “repetitive activity of the jaw muscles, characterized by clenching or grinding of the teeth and/or by bracing and pushing of the lower jaw”. This activity may or may not make a creaking sound.
Teeth grinding does not perform the function of the chewing system and can cause occlusal injury. The bite affects the function of the muscles, thereby affecting the temporomandibular joint. Therefore, any change in the bite affects both muscles and joints. Misaligned bite is one of the most common causes of teeth grinding. Its consequences can cause pain in the temporomandibular joint.
Teeth grinding at sleep: Appears in both adults and children. Usually back and forth grinding.

2. Causes of teeth grinding while sleeping
The cause of teeth grinding while sleeping is not really clear, but it is thought that teeth grinding is often related to the following factors:
2.1. Psychosocial factors
Stress Studies have reported that psychological factors have a significant influence on the disease, mainly a stressful lifestyle. Evidence in this regard is growing but inconclusive. Emotional stress is considered the main trigger. Nocturnal teeth grinding may be a response to ongoing or ongoing daytime stress. Stress can occur in people who work a lot, are oppressed; students are in exam season. When stress is accompanied by anxiety, repression can trigger brain activity. This increases nerve stimulation, which can trigger all of the reactions of teeth grinding.Personality: Strong, excitable people are more likely to get sick.
Age: Teeth grinding is common at a young age and usually disappears as we get older.
2.2 Genetic factors
People with family members who have or have had bruxism while sleeping are at risk of developing this condition as well. Research suggests that there may be some degree of genetic involvement in developing bruxism. 21-50% of people who grind their teeth at night have a family member who has had it before. This suggests that genetic factors are involved in the disease.

2.3 Drugs and Stimulants
Some side effects of drugs and narcotics that increase the risk of teeth grinding include: Dopamine agonists and antagonists. Tricyclic antidepressants. Selective serotonin reuptake inhibitors. Alcohol, cocaine..2.4 Local factors
Impaired occlusion can be a causative problem. They interfere with normal chewing movements. The cause can be in a single tooth or a group of teeth. Example: When the upper wisdom teeth are lost, the lower wisdom teeth erupt. When biting back, the lower jaw has to come forward more to close the jaw. This distorts normal jaw movement.

2.5 Whole body factor
Allergies: Due to intestinal parasites, digestive disorders or food allergies. These are the possible causes of severe bruxism in children (Marks, 1980).Nutritional, urinary, and endocrine disorders are also favorable factors for the disease, more common in children than in adults.
Vitamin deficiency, enzyme imbalance also affects the disease.
Central nervous system disorders that may be associated with the disease:
Cerebral palsy. Down's disease. Epileptic. Huntington's disease. Leigh disease. Meningococcal infection. Parkinson disease. Post-traumatic stress. Rett's syndrome.
2.6 Occupational factors
Certain occupations have special requirements that can cause teeth grinding or clenching. Example: The pianist grits his teeth while holding the piano while playing; porter workers gritted their teeth to exert themselves; Circus performers use their teeth to hold people in the air...2.7 Instinct factor
Some studies suggest that these habits are instinctive, behavioral activities of mammals. Its purpose is to maintain the sharpness of the teeth.3. Harm of teeth grinding while sleeping

4.4 Dental interventions
Dental treatment helps protect teeth from the harmful effects of teeth grinding while sleeping, but it is not certain that it will completely treat bruxism. One of the common interventions is the use of anti-crunch trays to help protect the tooth surface from abrasion.
Some types of troughs also have the effect of adjusting jaw movement habits, which can help limit teeth grinding. This jaw guard can be made of soft material or hard acrylic, suitable for each person's upper and lower jaw.
Adjust the bite position to reduce excessive impact on the chewing muscles as well as the teeth. If the tooth wear is much, the teeth are sensitive, the patient needs to restore the tooth shape to restore the tooth relationship between the two jaws and the bite to match.
Teeth grinding, although not life-threatening, is persistent and can cause serious harm to your teeth. Treatment of teeth grinding requires patience and coordination of the patient.
