TMJ & Bruxism

What is Bruxism?

Bruxism is the tendency of certain people to clench or grind their teeth by sliding or rubbing the teeth back and forth over each other. This habit can occur both during the day and at night, speaking of day or night bruxism, depending on the case. Night bruxism is usually more difficult to control. We do not know the exact causes of bruxism, but we do know the risk factors for suffering it. One of the main risk factors is stress, especially in daytime bruxism.

What is the TMJ?

The Tempor-Mandibular Joint, called TMJ, is made up of bones and muscles, ligaments and joint capsule that allow the mouth to open and close. It is found on both sides of the head, and both TMJs work simultaneously when chewing, speaking, or swallowing. The TMJ also controls the lateral and forward movements that the jaw can make.


Each TMJ has a meniscus between the head of the mandible (condyle) and the articular fossa. This meniscus is like a disk that, like a cushion, cushions the occlusal forces of the mandible and allows the mandible to open widely thanks to a first circular movement and then translation. Any alteration of this complex muscular, ligamentous and meniscal system can be the cause of TMJ dysfunction and pain.


Orofacial pain can have various origins and is often related to the TMJ (temporo-mandibular joint) and the muscles, ligaments, and tendons that relate to it.

Our Methodology

At Clínica Birbe, we begin by making a precise diagnosis of the origin of the problem and which will subsequently guide the most appropriate treatment to follow. For this, in addition to a complete interview and physical examination, we often require a scanner and / or MRI.

We have a first step of conservative treatments and measures to follow, and if they are not enough, we continue with infiltrations (arthrocentesis), closed surgery (arthroscopy) and, ultimately and in certain conditions, open surgery. The initial conservative treatments are:

  • Eat soft foods
  • Avoid biting your nails and gum
  • Apply heat to painful areas
  • Relaxation techniques to control tension at the jaw level such as biofeedback or meditation


Conservative treatments are physiotherapy in its various modalities and the use of the discharge splint. Intra-articular infiltrations or arthrocentesis have two objectives: to wash the joint and joint fluid of inflammatory molecules, and to inject anti-inflammatory medication. We also seek to make a hydraulic expansion of the joint, to recover the space necessary for the correct mobility of the meniscus.


Arthroscopy seeks, in addition to visualizing and washing the joint, to fix the meniscus in its correct position with a pin.


Open surgery for reasons of osteoarthritis is rare. In case of meniscus perforations or ruptures of the same. If there are joint pathologies such as tumors or ankylosis or fractures, each of them requires a specific surgical treatment.


Finally, in cases of great wear and tear and joint destruction, it may be necessary to place a TMJ prosthesis, similar to those used in the hip.
