Why does a child gnash his teeth in a dream and causesadults

Update: October 2018

Teeth grinding, otherwise called bruxism, is
unpleasant for the patient and troublesome syndrome for the doctor. More often
This phenomenon affects people with a labile nervous system. From
one to three percent of the world’s population (both adults and
childhood) are subject to this condition.

The most common is the night variant of bruxism, but the daytime
gnashing of teeth also occurs. Today fully explored
the main groups of diseases and pathological conditions leading
to that.

Why does a child gnash his teeth in a dream? At the heart of bruxism lies
involuntary spasm of the masticatory muscles, closing of the jaws and their
convulsive uncontrolled movement in the antero-posterior or lateral
directions. In this case, the teeth interlock with each other by chewing.
surfaces and move with friction, creating a rattle.

In addition, there may be impaired or stopped breathing in
sleep (apnea), slow pulse, drop in arterial
pressure. Gnashing lasts from a few seconds to

Symptoms of bruxism

If the child’s day or
an adult, then the night squeaking with his teeth, as a rule, he is told
relatives and friends whom such sounds scare or make not
sleep at night.

Characteristic manifestations of bruxism are:

  • Creaking or gnashing of teeth.
  • Pain in the muscles of the face and temporomandibular joints, especially in
    in the morning
  • Chronic воспаление височно-нижнечелюстных суставов с
    ограничением объема движений нижней jaws.
  • Enamel hypersensitivity to cold, sweet,
    hot because of its gradual erasing and shedding.
  • Traumatic chipped or broken teeth, their loosening.
  • BUTномалии прикуса, формирующиеся в результате стирания зубных
    rows and their deformations.
  • Violations of the depth of night sleep lead to permanent
    lack of sleep and the syndrome of chronic fatigue, daytime sleepiness and

What else is unpleasant bruxism

  • In addition to objective physical changes in the state
    osteo-articular apparatus, muscles and teeth is a considerable problem
    the discomfort of the patient’s close environment and gradual
    neurotization itself gritting his teeth, if the fact of the teeth creak
    becomes known to him.
  • Bruxism can be a contraindication for the installation of crowns.

Theory of the effect of helminthic invasions

Quite often among the people there is an opinion that teeth grinding
in a dream, especially in children, is directly related to helminthic invasions
(see the symptoms of worms in children and roundworm in humans, pinworms in
children). It was this that justified the folk treatment of the rattle with
using garlic, used in various forms and quantities
(see tablets for worms).

In fact, the direct relationship between parasitization in
the body of worms and bruxism is not. May well be gritting his teeth
an adult or child who has no worms, and never has been.
A little bit scientific explanation of the fact that suffering
helminth infections, children also creak in their sleep with their teeth, reduced to two

  • First, any worm infestation can lead to neurotic
    patient (see the test for the presence of worms in humans).
  • Secondly, vitamin B12 deficiency, the synthesis of which decreases with
    many intestinal helminthiases (for example, infection with a wide ribbon)
    impairs neuromuscular transmission, which can be prerequisites for
    malfunctions in the chewing muscles and
    temporomandibular joints.
  • Third, the same B12 deficiency anemia worsens transport.
    oxygen to the brain, which can affect the change
    sleep depths and lead to various involuntary muscle contractions
    by the type of partial seizures, including chewing triphasm

Causes of night rattle in children

According to various sources, teeth grinding is found in
15-50% of the child population.

The reasons for this most often lie in the plane of the neurological
problems, frequent fatigue or asthenia, and anomalies in
the structure of the facial skeleton, jaws and bite pathologies.

  • Sometimes wheezing occurs after a long infectious
    illness or after weaning a baby from the nipple, to which he is severely
    got used to.
  • Do not deny the influence of heredity. About 80% of children
    suffering from night squeak the same problems at different ages
    suffered at least one of the parents.
  • Diseases of the digestive tract.
  • Diseases of the temporomandibular joint.
  • Skin allergic diseases.
  • BUTденоиды у детей

Up to 80% of children suffering from adenoids also have an accompanying
bruxism. it также связано с уменьшением глубины сна и нарушением
nasal breathing, which at different times of the day stimulates

  • Skip teeth and epilepsy

Interesting research that sought a relationship between bruxism and
epilepsy. According to the EEG in children with bruxism, the phase is shortened
falling asleep, teeth squeak episodes often occur at the junction of the first
slow phase and second fast phase sleep. There is a direct link dental

epilepsy. Most often, bruxism affects hypermobile children who
early began to sit, stand, walk, as well as children who started
talk earlier peers.

If the child suffers short (up to 10 seconds) and rare

stay at the computer. Quite often such episodes pass
independently and without any treatment.


What is the danger of grinding for a child?

When a child gnashes his teeth at night, the risk increases
traumatizing the teeth and the occurrence of lower joint diseases

From the mutual pressure of the teeth on each other, the edges of the crowns
wear out. If Burxism lasts for years, it may appear

jaws a child may wake up with a toothache or a headache without
get enough sleep.

An adult grits his teeth for the following reasons.

Inflammation of the temporomandibular joints

Sooner or later it leads to dysfunction of the joints. it
violation can be heard as a click during wide opening
mouth (when yawning or biting large pieces). Chronic
inflammation in the temporomandibular joint causes
increased nervous impulses stimulating sudden spasm
masticatory muscles. When muscles contract, they move the lower one.
jaw, which reproduces tooth gnash. Here arises
vicious circle: muscle spasm is provoked by inflammation, and
this inflammation supports, breaking the normal ratio
articular surfaces.

Nervous disorders

The presence of a chronic neurotic state, exhaustion of the nervous
system on the background of prolonged mental or physical stress.
Nervous bruxism occurs most frequently on the nerve soil. Because
One of the functions of sleep is to rid the nervous system of excessive
information and its processing, in a dream a person often continues
experiencing daytime problems and not being able to fully
relax, grit your teeth.

  • Night bruxism coincides with the phase of REM sleep and with episodes
    restless sleep: involuntary muscle twitches, active
    eyeball movements.
  • Often the creak of teeth is combined with snoring, talking in a dream,
    with cure and even enuresis.
  • Such patients often have a bad habit during the day,
    especially in moments of emotional stress, nibble objects
    (pencils, pens, matches, toothpicks) or nails.

Action of neurotoxins

The most common household poisons that poison the central nervous
the system is alcohol, nicotine, and nitrocoloring.

Dental problems

Pathologies and anomalies of the dentition and jaws:

  • malocclusion
  • the presence of poorly fitted fixed prostheses
  • inflammation in the area of ​​implants can lead to spasm
    chewing muscle and bruxism
  • a frequent example of trisism (that is, a long, painful
    spastic contraction) masticatory muscles may become obstructed

Consult a neurologist, dentist, allergist, pediatrician
(to the therapist).

If the attacks are frequent and prolonged, combined with other
manifestations of disturbed sleep depth (enuresis), then the child’s
necessarily show a neurologist (performed EEG and
examination of the fundus oculist, appointed sedatives

corrected by silicone tires with air dampers,
since the age of three to five years.

For the diagnosis you need to pass a complete blood count for the content
blood calcium, enterobiosis tests and eggs of the worm. If there is
black plaque on the teeth, this is another reason to test for
helminthiasis, it can also be for diseases

Find out the possible causes of stress in a child. What are the changes
occurred in his life (stress in kindergarten, the birth of a brother or
sisters) and try to limit the factors that cause stress.

Some recommendations should be followed before bedtime and not

  • Do not play active games for 2 hours before bedtime, only calm,
  • Do not eat in the last 2 hours before bedtime;
  • Take a bath to relax with herbal decoctions
    (valerian, chamomile, motherwort, turn, conifers);
  • Before bed, rub into the collar area and whiskey distracting ointment
    (eucalyptus, thyme)
  • Conduct myogymnastics (for face and chewing muscles) to
    relieve tension – circular movements of the tongue, stretching the tongue
    up and down, lip folding and wide opening
  • Relieve muscle tension solid foods, give them to a child
    in the evening (radishes, apples, raw carrots);
  • Adequate time to spend in the fresh air to avoid
    oxygen starvation of the brain.
  • Do not drink beverages that excite the nervous system at night (strong
    tea, coffee, energy drinks, alcohol, gazirovok).
  • Herbal sedatives.
  • Dry heat on the area of ​​masticatory muscles at bedtime.
  • Silicone caps

They prevent teeth from being erased, make them in
dental laboratory in the direction of the dentist. mouth guard
set in the mouth before bedtime. She is not only not
allows teeth to contact each other when creaking and
wear off, but also forms the correct bite. You can buy and
standard mouthguard and adjust it to your bite. it
The orthodontic appliance consists of two parts, each
which is equipped with a handle-petal. Both parts are omitted in
capacity with boiling water for 8-10 seconds to give the silicone
ductility, then shake off drops and are inserted into
mouth. Then you need to forcefully squeeze the jaws three-fourth times,
leaving a clear impression on the cap. Further handles are cut. BUT
the finished cap will be tight enough to hold in your mouth,
not allowing you to erase teeth with a grinding.

  • In daytime bruxism, dentists also use
    various tire modifications that are not visible in the mouth and
    perfectly prevent the full closure of the dentition and abrasion
  • In the most severe cases, the doctor may prescribe an adult coursework.
    taking muscle relaxants or antidepressants.

Thus, bruxism today refers to the phenomenon of
different areas of medicine. Therefore, long episodes of grinding
adults, especially children, should be examined as
at least two specialists: a neuropathologist and a dentist.
