What reason is infantile sleep molar

summary

Molars in sleep are more common in children, adults can also occur. The contraction of masticatory muscle is controlled by trigeminal nerve. When trigeminal nerve is excited, it will lead to repeated contraction of masticatory muscle. The upper and lower teeth collide with each other and make a sound, which leads to molar phenomenon. When molting teeth at night, the teeth form "dry grinding",. Ah, wear is very serious, leading to varying degrees of sensitivity. This kind of excessive chewing can also lead to the destruction of the tissue around the teeth, make the teeth loose and shift, and even cause gingival atrophy or alveolar bone loss. The main causes of molars at night are as follows

What reason is infantile sleep molar

Reason 1: biliary tract parasites are mostly caused by biliary Ascaris. Ascaris lumbricoides can secrete a variety of toxins. In addition, the metabolites of Ascaris lumbricoides can stimulate the corresponding parts of the brain in deep sleep, causing some people to have continuous contraction of masticatory muscles and molars.

Reason 2: occlusal disorder, which is the most important reason for the occurrence of nocturnal molars. Occlusal dysfunction destroys the coordination of masticatory organs, so the body increases tooth grinding to remove occlusal dysfunction. Dental caries is not treated in time, and then pulpitis, periapical periodontitis, pain, abscess, and even premature loss of deciduous teeth will occur, which will lead to unilateral mastication habit, long-term unilateral mastication, uneven occlusion and occlusal disorder, resulting in persistent nocturnal molars; Uneven dentition, such as crowding, reverse occlusion, open occlusion, etc., will make the occlusion uncoordinated, resulting in molars at night.

The third reason: mental and psychological factors include mental stress, fright, emotional excitement and fatigue. After sleeping, although the cerebral cortex is in a state of inhibition, there are still some areas (such as the trigeminal nerve) in an excited state, leading to molars.

matters needing attention

Improper diet for a long time can lead to gastrointestinal dysfunction and molars. The lack of vitamins and trace elements in the body is also prone to bruxism. For example, a considerable number of children's bruxism at night is caused by partial food, picky food and unbalanced body nutrition.
