prevalence of bruxism

In varying degrees, bruxism is inherent in a sufficiently large number of people, and is directly linked to the activity of the nervous system.In some cases, manifested in daytime and in varying degrees is typical for most people during sleep.

According to one version, bruxism is a reflex-atavism, aimed at sharpen

ing the cutting surfaces of the teeth in higher mammals during sleep.This type of night bruxism occurs most often in children.In adults, this phenomenon occurs in the daytime, with a somewhat different meaning.

bruxism during wakefulness is a reflex distraction means reducing pain from any source component.The activity of the masticatory muscles allows you to escape, and it becomes one of the bad habits, such as Onychophagia (biting), for example.

Ground off the teeth with bruxism

teeth with bruxism can be ground off seriously

Constant creaking teeth called bruksomaniey.This is a serious dental problem leading to a variety of complications.In some cases, the treatment of this habit is necessary to consult a psychiatrist (except, in fact, the very psychic dependence, bruxism is often linked to mental disorders).

On average, one in five adults suffers bruksomaniey

first pay attention to this phenomenon close "bruksomana" and, of course, dentists.Advanced cases are accompanied by violation of the bite, the deformation of the dentition, which makes it extremely difficult situation even correction with implants.

main causes of teeth grinding

Chewing - one of the oldest functions in vertebrates, so chewing movements are accompanied by a variety of mental states, including subcortical origin.In addition, the observed relationship between bruxism and a wide variety of medical conditions.

Bruxism is a common companion of headaches, especially migraines.Even in the literature can be found phrases like this - "... he gritted his teeth in pain."Indeed, gritting his teeth, like a cry, relieves tension in pain impulses.That is why bruxism is a constant companion of migraines in women, as well as gastroduodenal headaches.

Toothache, oddly enough, also causes aggravation of this bad habit.Partly this is due to the scattering effect of the process of creaking teeth, in part - the need to "control" the pain of proprioception.

Maxillofacial trauma and inflammation of the musculo-ligamentous apparatus of the skull are also accompanied by bruxism.In this case (with prolonged inflammation with only one hand), asymmetric teeth erased.

Besides pain in the masticatory and facial muscles, bruxism is often accompanied by otalgia (ear pain).This phenomenon is observed in chronic otitis (from any source).Sometimes otitis it manifested tinnitus, which is usually accompanied by increased chewing activity.

In children, as the formation of the vestibular apparatus, quite often there are episodes of vertigo, ie,vestibular vertigo.Bruxism occurs at this point as a compensatory mechanism for blocking vomiting and loss of balance.

Sinusitis - one of the causes of bruxism

chronic rhinosinusitis (sinusitis, sinusitis, ethmoiditis) is also accompanied by gnashing of teeth.

Bruxism in children, in some cases just points to a chronic inflammation in the maxillary (or other) sinus.Pain redistributed component, which leads to the appearance of the night grinding.Moreover, the child may not feel at all during the day soreness.

Bruxism caused by peripheral diseases and processes

Acquired bruksomaniya is enhanced by alcohol abuse, severe stress, smoking.

Bruxism is one of the signs of poisoning with amphetamines.Increased physical activity caused by the action of psychotropic drugs requires constant motion and muscle contractions.If such a "energizers" stop for a moment, you can immediately hear the creak of the teeth.

Thus bruksomaniya formed, as a rule, at a constant source of pain.

good example confirming this statement is the fact that half of the patients with severe degenerative disc disease of the cervical, thoracic and lumbar spine bruxism observed varying degrees of severity.

osteochondrosis and other painful conditions - one reason why bruxism

same is true for patients with lumbago, shoulder injuries and spinal pain.

hunger as hunger pains and gastritis, provoke paroxysms of bruxism.

If a patient with gastritis begins to creak teeth - is to feed him because bruxism is one of the elements of the "aura" hungry pain (there are creaking a little later).

psychogenic causes

main cause of bruksomanii adults - stress.Although it is not the pain in its pure form, however, the DC voltage of the nerve cells is always trying to allow the automatic muscular movements.So formed, almost all bad habits, including grinding of teeth in adults.

When mental illness - there is absolutely the same, but the intensity of the phenomenon is much higher.This explains the ongoing dental problems of mentally ill people.

Stress - one of the possible causes of the problem

Quite often accompanied by sleep disturbances creaking teeth. This may be due to the load of psychogenic (nightmares, psychotic disorders), and diffuse pain with physical nature affecting the sleep phase and potentiates bruxism in adults.

Bruxism insomnia is usually already formed bruksomaniya.The patient constantly grinding his teeth.Without these movements the opportunity to sleep is reduced practically to zero, which gives unpleasant moments close, and requires consulting a dentist becauseteeth are erased quite intensively.

If you see persistent episodes of bruxism at or close (proprietary bruxism is not always possible to detect), consult your dentist.When bruksomanii a child - start active treatment of this condition, it will help avoid serious problems with the bite and reduce the risk of premature failure of the teeth.
