Teeth grinding refers to the unconscious behavior of grinding or clenching the upper and lower teeth against each other. It is also called “nocturnal bruxism” because most cases occur at night during sleep. A long-term study by Japanese scholar Sadao Sato shows that 99% of people grind their teeth to a greater or lesser extent. Occasional teeth grinding is not called bruxism, and the teeth and the body is not a big problem, but is an effective way to release the mental pressure, but the long-term serious teeth grinding formed bruxism is always damaging to the patient’s oral and general health. Teeth grinding causes: (1) work pressure, nervous tension, psychological anxiety, depression, anger and other psychological factors. (2) Gastrointestinal diseases, endocrine disorders can also lead to this, a small number of parasitic patients also appear such symptoms. (3) Long-term irregular life, excessive fatigue, engaged in fine workers, such as athletes, watchmakers and so on. (4) Lack of trace elements in the body is easy to suffer from this disease. (5) Habitual teeth grinding disorder formed by long-term teeth grinding. Grinding teeth at night when the bite force is more than 3 times the normal people in normal chewing, the bite force is only 30 kilograms, and severe teeth grinding teeth bite force is very large, doubled, can be more than 100 kilograms, thus bringing harm. Therefore, the damage of teeth grinding to oral and general health are: 1, serious wear and tear of teeth. Long-term night grinding will not only cause wear and tear of the occlusal surface of the teeth, but also increase the generation of fissures on the surface of the teeth and the cervical cuneiform defects, and in severe cases, there is pain and discomfort in contact with cold, heat, acid, sweet, or even necrosis of the dental nerve. 2, there is damage to the periodontal tissues. As a result of long-term teeth grinding, excessive occlusal force is transmitted to the alveolar bone, which can cause gingivitis and periodontitis, and make the teeth loose and fall off prematurely. 3.Impact on temporomandibular joint. As a result of long-term teeth grinding, excessive occlusal force is transmitted to the temporomandibular joints, leading to joint “click” when opening and closing the mouth, joint pain and other uncomfortable symptoms. 4, cause facial pain and headache. Prolonged teeth grinding leads to fatigue and pain of chewing muscles, pain in the cheeks, and in severe cases, headaches and neck and back pain. 5.Cause mental burden. Night grinding of teeth not only affects the patient himself, but also brings unhappiness to others, so it is easy to make the patient mentally nervous, poor sleep quality, memory loss, damage to hearing and sense of taste, and even lead to psychological depression and other more serious consequences. Reducing mental stress is critical ah! As mentioned earlier, occasional teeth grinding is not harmful to your health, but severe teeth grinding disorder should be actively treated. Although so far there is no better way to completely eliminate teeth grinding, but can be effectively controlled, so that it is less serious, and reduce the resulting damage, the goal can be achieved. 1. Orthodontic treatment. As mentioned earlier, malocclusion of the teeth, especially in the posterior region, strains the masticatory muscles and aggravates bruxism. We can align the teeth by orthodontic treatment to eliminate occlusal interference and establish physiologic occlusal induction, thus effectively reducing the severity of bruxism. 2. Wear a bite plate or a nighttime grinding pad. It can reduce the pressure on muscles and joints and protect the damaged teeth. 3. Reduce mental stress. Patients should make efforts to relieve mental tension and unpleasant emotions, which have positive significance to the treatment and prevention of bruxism.
