So how does the baby grind teeth during the day? How should parents deal with it? The upper and lower teeth bite and make a sound, which is what we call molars. Molars are caused by the continuous contraction of masticatory muscles, and the movement of masticatory muscles is controlled by the trigeminal nerve, so all factors that can affect the trigeminal nerve and masticatory muscles can cause baby molars.

The reason why babies grind their teeth during the day.
The upper and lower teeth make a sound when they bite, which is called molar. Molars are caused by the continuous contraction of masticatory muscles, and the movement of masticatory muscles is controlled by the trigeminal nerve, so all factors that can affect the trigeminal nerve and masticatory muscles can cause baby molars.
1) Over excited and nervous
Baby play too much, too excited or tired, or frightened, restless and anxiety, or learning tension, so that the excitation and inhibition process of the cerebral cortex out of balance, induce masticatory muscle movement, the occurrence of temporary irregular spasm or contraction, will produce the molar.
2) Intestinal parasitosis
Ascaris lumbricoides like to move in children's intestines and secrete a variety of toxins. The toxin stimulates the intestines, accelerates the peristalsis of intestines, causes dyspepsia and periumbilical pain; if the toxin stimulates the nerves, the nerves will be excited and molars will be caused. Enterobius vermicularis also secretes toxins, causing anal pruritus, affecting children's activities and making molar sounds.
3) Digestive disorders
For example, if you overeat, a large amount 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.
4) Nutrition imbalance
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, resulting in the involuntary contraction of facial masticatory muscles and the grinding of teeth.
5) Others
During the period of changing teeth, tooth dysplasia can cause occlusal disorder, chronic periodontitis, psychomotor epilepsy, hysteria and so on.
The Countermeasures of baby grinding teeth during the day.
1. If the child has intestinal parasites, it is necessary to expel them as soon as possible. The commonly used insect repellents are qusuanling, Anlesi, changchongqing, levamisole, etc.
2. Children with rickets should be supplemented with proper amount of calcium and vitamin D.
3. Give children a comfortable and harmonious family environment and avoid over excitement.
4. The diet should be matched with meat and vegetables, and the bad habit of being picky about food should be changed. The dinner should be light and not excessive.
5. Parents can give the baby some small food for molars, such as molars stick, molars cake, etc. to ease the molars, and practice chewing and promoting the eruption of deciduous teeth. A little harder vegetables, fruits, grains can come in handy.
6. Ask the stomatologist to carefully check whether there is bad occlusion. If there is, you need to grind off the high point of the teeth and prepare a dental pad. After wearing it, the baby will reduce the number of molars.
