grinding teeth is a term for grinding teeth or clenching the jaws. Teeth grinding often occurs during deep sleep stages or when children are under stress. According to research, this condition is reported more in boys than in girls. Improper alignment of teeth or abnormal contact between the lower and upper teeth, nutritional deficiencies, anxiety and stress problems of children, parasites of the digestive system, allergies, etc. are among the causes of this disorder. This behavioral complication is related to mental stress that the child had during the day and causes teeth grinding in sleep at night. There is no medical treatment for grinding teeth, it is recommended that children do not use caffeinated substances such as chocolate and tea at night. According to new research, if teeth grinding is caused by stress and nervous disorders this condition will be resolved by the age of 12 and parents should place their child under the supervision of a specialist doctor in terms of dental health.
Causes of teeth grinding:
Experts are not always sure why teeth grinding occurs. In some cases, children may have misaligned upper and lower teeth. Children may pull their teeth as a way to relieve pain, just as they might rub a muscle.
Stress – usually nervous tension or anger – is another cause. For example, a child may be worried about a school test or a change (new sibling or new teacher). Even arguments with parents and siblings can cause enough stress to trigger teeth grinding or jaw clenching.
Some hyperactive children also have teeth grinding. And sometimes children who have other medical conditions (such as cerebral palsy) or people who take certain medications can have teeth grinding.
Many cases of teeth grinding go undetected without any complications, while others cause headaches or earaches. But usually the sound related to teeth grinding (Bruxism) is more annoying for other family members.
In some cases, grinding and squeezing tooth enamel can cause enamel loss, increased sensitivity to temperature, and severe facial pain and jaw problems such as temporomandibular joint disease (TMJ).
Many children who grind their teeth are not even aware of it, so it is often siblings or parents who recognize the problem.
