What's the reason for baby's grinding teeth at night?
summary
Sleep state, the upper and lower teeth bite sound, is the daily said molar. Sleeping molars are caused by the continuous contraction of masticatory muscle, and the movement of masticatory muscle is controlled by trigeminal nerve. Therefore, all factors that can affect trigeminal nerve and masticatory muscle can cause sleeping molars. What's the reason for baby's grinding teeth at night? Let's talk about it.
What's the reason for baby's grinding teeth at night?
(1) Excessive mental excitement and tension, excessive play, excessive excitement or fatigue before going to sleep, or being frightened, uneasy and anxious, or learning tension, make the excitation and inhibition process of the cerebral cortex out of balance, induce the movement of masticatory muscles to produce temporary irregular spasm or contraction, and produce night molars.
(2) Intestinal parasitic disease Ascaris lumbricoides like to move in the intestines after children fall asleep, and secrete a variety of toxins. Toxin stimulates intestinal tract, accelerates intestinal peristalsis, causes dyspepsia, periumbilical pain and restless sleep; If the toxin stimulates the nerve, the nerve will be excited and the molars will be damaged. Pinworms also secrete toxins, causing anal pruritus, affecting children's sleep and making molar sounds.
(3) Digestive disorders, such as eating too much before going to bed, a lot of food fills the gastrointestinal tract and stimulates the digestive tract. Nerves transmit these stimuli to the brain, which excites the brain cells that manage digestion and causes molars through reflex action.
matters needing attention
(1) Eliminate tension: remove unnecessary concerns, open-minded, reasonable arrangement of work, oral diazepam tablets if necessary, 1-2 times a day, one tablet each time（ 2) Develop good living habits: regular daily life, dinner should not be too full, do not do strenuous exercise before going to bed, especially children should develop the habit of hygiene（ 3) Suspected of intestinal parasites: under the guidance of a doctor, deworming treatment should be carried out to reduce the intestinal parasite peristalsis and stimulate the intestinal wall（ 4) Correct bad habits of the dental system, such as unilateral chewing, pencil biting, etc.
