Previous studies have confirmed that the causes of children's sleep on molars are: (1) mental stress or frolicking during the day, and the cerebral cortex is still in a state of high excitement at night; (2) think every day and dream at night. The child's panic, anger and hunger in his dream lead to grinding his upper and lower teeth; (3) Eating too much dinner makes the stomach full and uncomfortable, stimulates gastrointestinal nerves and reflexively causes the excitability of cerebral cortex to increase; (4) A variety of toxins produced by Enteroascaris lumbricoides stimulate brain nerve excitement; (5) Oral diseases, such as gingivitis, periodontitis and alveolar abscess, can cause pain and soreness, and also lead to grinding teeth.
To sum up, children's sleeping grinding is a chewing exercise without chewing purpose, and intestinal ascaris is only one of many incentives for sleeping grinding. Children's health care experts pointed out that children's sleeping molars themselves will cause slight harm to the body and have no obvious impact on the body. Mild (not grinding teeth every night) and moderate (occurring every night) generally do not need treatment; For serious cases, there are tooth injuries and temporomandibular joint abnormalities every night, which need to be corrected in the stomatology department of a regular hospital. Before going to bed at night, you can take a proper amount of sedatives such as diazepam, which can improve sleep on the one hand and relax the masticatory muscles on the other hand, so that the phenomenon of grinding teeth disappears.
