It is normal for children to grind their teeth during the dental replacement period Adult teeth grinding should be paid attention to

Why do I grind my teeth while sleeping? Molars are when the chewing muscles contract involuntarily in a non-physiological functioning state, causing the upper and lower teeth to grind or clench with each other. The phenomenon of teeth grinding is mostly present in children's groups, adults also have such phenomena, children between the ages of 6 and 13 years old belong to the tooth replacement period, in order to adapt to the running-in of upper and lower teeth in the tooth replacement stage, so there will be a phenomenon of teeth grinding, which is normal. However, if adolescents and adults who have passed the tooth replacement period still have teeth grinding, they should pay attention to it.

There are many reasons why people grind their teeth while sleeping, which may be parasites in the gastrointestinal tract, mental stress before going to bed, sleeping on their stomachs, uncoordinated teeth bite, genetic factors, calcium deficiency and so on. The cause of teeth molars is that the cerebral cortex can innervate part of the cells in the motor area of the jaw, and in some cases abnormal excitement leads to trigeminal nerve dysfunction, which innervates the body's chewing muscles, and when the chewing muscles enter a state of abnormal activity, they will grind their teeth.

Grinding teeth mainly bite and grind two actions, bite is mainly reflected in clenching teeth or tapping up and down, the damage to the gums is relatively large, even when it is serious, there are even bites of the gums, cracked teeth; grinding is manifested as upper and lower teeth grinding hard, and accompanied by sound, because sleep when the oral secretion of saliva is less, so the teeth are in a dry grinding state, so the degree of wear of the bite surface of the teeth is larger. Long-term molars may cause abnormal wear on the occlusal surface of the teeth, the enamel on the surface of the teeth will be slowly destroyed, and the fragile dental nerves inside will be gradually exposed, which will affect normal eating due to stimuli such as hot and cold, sour and sweet, and in severe cases, it will lead to dental nerve necrosis. Prolonged teeth grinding can also cause the chewing muscles on both sides of the cheeks to not rest, causing pain in the cheeks and around the ears.

If there is a long-term grinding of teeth must be paid attention to, it is best to go to the gastroenterology department of the hospital for examination, if there is a parasite in the gastrointestinal tract, to take deworming drugs according to the doctor's recommendations, if it is because of uncoordinated teeth bite and other factors, teeth should be orthodontic, if it is because of excessive pressure and other factors, it is necessary to adjust living habits appropriately, pay attention to sleep, mental relaxation, and avoid excessive fatigue.
