1. Incorrect sleeping position
Many people are used to sleeping in a fixed position. If the posture is wrong, it will be difficult to sleep. In fact, this will easily lead to uneven lower stress, joint position change, tooth interference and contact, which will increase the tension of mandibular muscles and lead to molars.
2. Unbalanced nutrition
Whether adults or children are picky eaters, they will eat whatever they like and never eat what they don't like, which will easily lead to imbalance in nutrient intake, such as the lack of calcium, phosphorus and various vitamins, which will lead to grinding their teeth at night and may unconsciously bite their teeth when they concentrate during the day.
3. Improper tooth arrangement
Frequent unilateral chewing, or uneven growth of the teeth themselves, will lead to disharmony of teeth occlusion, and then the body will improve the occlusal disorder by increasing the movement of molars, thus producing molars. It should be reminded that when children change their teeth, they will subconsciously have more intimate contact with their teeth because of the disharmony of occlusion. After falling asleep, this idea will turn into grinding your teeth at night.
4. Mental reasons
When sleeping at night, people are in a relaxed state, but some of the stress during the day still does not dissipate, still controlling our brains, or we are too excited during the day, so that we can't sleep peacefully, and a small part of the cerebral cortex is still in an excited state, which in turn causes the masticatory muscles to contract the molars.
5, gastrointestinal dysfunction
Because three meals at ordinary times are uncertain, or eating a lot at dinner often leads to gastrointestinal dysfunction, which will lead to excessive toxin secretion by bacteria in the gastrointestinal tract. After the cerebral cortex is stimulated by these toxins, it will interfere with its excitement or inhibition process, resulting in sleep grinding. If children often grind their teeth, they should also be alert to the possibility of intestinal parasites.
At the same time, grinding your teeth while sleeping can also cause certain harm.
1, affecting sleep quality.
Sometimes, people's subconscious can feel that they are grinding their teeth, and it is easy to lose sleep.
2, causing tooth displacement or looseness.
Masticatory muscles will also become bulky. In the long run, people's faces are likely to change, affecting the beauty of their faces.
3, affect dental health
The direct friction between teeth will cause great damage to the enamel on the tooth surface, and the teeth may become sensitive and fragile, which will lead to symptoms such as gingivitis and gingival atrophy, and the dentin protected by it will also be damaged. The nature of molars is different from that of teeth when chewing. There is food and saliva between the upper and lower teeth of the latter for lubrication and buffering, instead of grinding teeth as dry as the former.
4. Emotion will be affected
Long-term grinding teeth will make the masticatory muscles in a state of exhaustion. Over time, the cheeks will feel sore, the temples will have a prominent feeling, and the head will become very painful. This will make you feel uncomfortable, and your mood and mood will naturally get worse.
To sum up, grinding teeth is caused by many reasons, but no matter what the reason, treatment is necessary. Therefore, for the sake of your physical and mental health, you should correct the habit of grinding your teeth in time and maintain good sleep habits, dietary preferences and living habits.
