What is the reason that darling grind teeth at night

summary

What's the reason for baby's molars at night? When sleeping, the upper and lower teeth bite and make a sound, which is what we call molars. 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 is the reason that darling grind teeth at night

Reason 1: mental hyperactivity, tension, excessive play before going to sleep, too excited or tired, or frightened, restless and anxious, or nervous learning, so that the excitation and inhibition process of the cerebral cortex out of balance, induce the movement of masticatory muscles have a temporary irregular spasm or contraction, resulting in the night molars.

Reason 2: intestinal parasitic disease Ascaris lumbricoides like to move in the intestines after children fall asleep, and secrete a variety of toxins. The toxin stimulates the intestines, accelerates the peristalsis of intestines, causes dyspepsia, periumbilical pain and restless sleep; if the toxin stimulates nerves, it causes nerve excitement and leads to molars. Pinworms also secrete toxins, causing anal pruritus, affecting children's sleep and making molar sounds.

The third reason: 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

Some children have the habit of being picky eaters, especially those who don't like to eat vegetables, resulting in unbalanced nutrition, resulting in the lack of calcium, phosphorus, various vitamins and trace elements, causing involuntary contraction of facial masticatory muscles at night, and grinding teeth back and forth.
