What causes a four-year-old child to grind his teeth?

I believe many people are familiar with the condition of grinding teeth while sleeping. This is a disease that often occurs in children. The occurrence of this disease causes great damage to the teeth, especially for children whose teeth are still developing. However, many parents do not know how this condition is caused. So, what is the reason for a four-year-old child to grind his teeth?

First, what is the reason for a four-year-old child to grind his teeth? Teeth grinding directly damages the teeth. Grinding your teeth every night will cause premature wear of your teeth. The outer enamel will be worn away, exposing the pulp, causing dentin hypersensitivity, and pain will occur when exposed to cold, hot, sour, sweet and other stimuli. In addition, damage to periodontal tissue can easily lead to periodontal bruxism. Due to nighttime bruxism, facial muscles, especially chewing muscles, constantly contract. Over time, the chewing muscle fibers become thicker, the face shape becomes square, and the beauty of the child's face is affected. If the tooth tissue is severely worn, the height of the teeth decreases, and the facial muscles are over-tired, temporomandibular joint disorder syndrome will occur. When talking, singing or eating, the mandibular joint and local muscles will be sore, and it may even be difficult to open the mouth. The mandibular joint may make a hissing noise when opening the mouth, and some people may even experience mandibular dislocation. In addition, it can also cause symptoms such as headache, facial pain, insomnia, and memory loss.

Second, the child has roundworms in his stomach. They rob various nutrients in the small intestine, secrete toxins, run around, and are extremely restless. They stimulate the intestinal tract to speed up peristalsis, causing indigestion and dull pain around the navel. This can make the child's nervous excitability unstable during sleep and cause teeth grinding. Children with pinworms often have pinworms crawl to the anus and lay eggs after going to bed, causing anal itching, restless sleep, and nocturnal grinding of teeth.

What is the reason for a four-year-old child to grind his teeth? Children with bad habits of being picky eaters are prone to lack of calcium and vitamins; some children often "don't want to eat breakfast, but fill their stomachs with food at dinner." This phenomenon can easily cause digestive dysfunction, because they eat too much at dinner and there is still food accumulated in the gastrointestinal tract when they go to bed, so the gastrointestinal tract has to work overtime to complete the task of digestion and absorption. When the stomach is working, it also causes the facial chewing muscles to contract spontaneously, causing the teeth to grind back and forth.
