Temperomandibular Disorders TMD

Connection of jawbones and skull

TMJ is used for opening the lower jaw, speech, and mastication. This is the joint that moves in three dimensions and is always at rest. The muscles on both sides that are on the right and the left will work in unison to keep the joint in a centric position where all the muscles are at rest .

Temporomandibular joint acts like a connection between the mandible and the skull. Usually, TMJ disorders is a multifactorial disorder. Either it could be a functional problem(improper fit in the occlusion) leading to deviation in the jaws or it could be a psychological problem or habitual. Hence, doctors would initially examine the cause of the TMJ disorder. All these patients represents signs and symptoms of dental caries and gum problems.

The contemporary dental treatment will focus on the condition of the individual. Individuals, most of the time, live in a stressful state, which leads to a lack of sleep at night. Improper sleep will lead to the clenching of the teeth, and this directly causes a sprain in the  temporomandibular joint (TMJ).

When the patient is psychologically or mentally disturbed, sleep disorders or any malocclusion or any cant would cause damage in the occlusal table . This can lead to the deviation of the joints from the normal position, and it will cause spasm of the mastication muscles. Pain begins to radiate on the sides of the neck and moves down to the shoulder and other parts of the body.


Temporomandibular disorder means a set of symptoms as severe  as:

  • • Continuous headache

  • • Ringing in the ears or tinnitus

  • • Severe neck pain

  • • Migraine

A TMJ disorder is an initial part of the disease, and neuromuscular disorder is a more aggressive part of the condition where the individual experiences pain all over the body. Depending on the patient’s symptoms or early signs, the doctor will decide whether to treat TMJ disorder or to treat the whole body to eliminate the signs of the psychosomatic pain leading to neuromuscular disorder. A doctor who has specialized in neuromuscular dentist  alone can treat the temporomandibular disorder.
