Disorders of the
temporomandibular joint

Dr. Seica, your dentist in Blainville, is committed to offering you all the dental services you need to maintain optimal oral health. Among the services we offer is the management of temporomandibular joint disorders, i.e. the jaw joint.

Thanks to her extensive training at the Canadian Occlusion Institute, Dr. Seica is able to evaluate your jaw joints to identify any problems that may be causing pain or tension. She will then suggest treatments that will allow you to resume eating, speaking and laughing with complete peace of mind.

Origin and consequences of disorders of the
temporomandibular joint

The temporomandibular joint (TMJ) is the point where the mandible (lower jaw) attaches to our skull (upper jaw). Without us really realizing it, the TMJ is one of the most stressed joints in our body. In fact, it allows us to speak, laugh, yawn, eat, etc. We use it every time we open our mouths.

To understand the origin of TMJ disorders, we need to know the anatomy of the TMJ. Within the TMJ, there are muscles, bones, nerves, blood vessels as well as a part that plays a very important role, the articular disc. This disc is located between the two jaws and serves to absorb the pressure exerted by the jaws, while preventing friction. In some patients, the significant pressure that is repeatedly exerted on the articular discs can cause them to wear out or shift. This can lead to joint and muscle dysfunctions, which can cause various symptoms: headaches, pain in the neck, in the ear area, as well as in the face.

In some cases, TMJ disorders can also be the cause of mechanical dysfunctions. People may experience significant pain when the TMJ is stressed and cracking sounds may be heard. In some cases, the dysfunctions can reduce the ability to open the mouth properly, or even lead to problems with the occlusion of the teeth (the relationship between the upper and lower teeth).

Causes and treatments
of disorders of the
temporomandibular joint

Possible causes of TMJ disorders

  • Trauma (shocks) to the jaw ;
  • Bruxism, the unconscious grinding of the teeth ;
  • Dental malocclusion, which can lead to TMJ imbalances ;
  • Osteoarthritis, which affects the health of the joints ;
  • Loss of permanent teeth and other oral problems that cause imbalances in the mouth ;
  • Stress in general.

Possible treatments for TMJ disorders

If necessary, Dr. Emmanuelle Seica will perform a complete TMJ examination to detect tension and/or any abnormal symptoms. She will then be able to diagnose the problem and direct you to the appropriate care.

  • Orthodontic treatment : If TMJ problems are caused by a malocclusion problem, orthodontic treatment may be recommended.
  • Treatment of other dental pathologies : other pathologies that may be the cause of TMJ disorders, such as bruxism, must be managed to avoid complications.
  • Prescription of anti-inflammatory drugs : In the case of minor problems, anti- inflammatory drugs may be suggested to reduce your pain.
