Conditions
Articular disc displacement
When the TMJ disc shifts out of position, clicking, locking or difficulty opening the mouth may appear. A precise assessment guides treatment.
- What it is. Internal derangements of the temporomandibular joint occur when the articular disc —the cartilage that cushions bone contact— moves out of its usual position.
- Symptoms. With disc displacement with reduction, the disc slides forward when the mouth is closed and returns on opening, often producing an audible click, sometimes with brief pain.
- How it is treated. At Kinésica we assess opening range, jaw tracking, joint sounds and muscle involvement.
What is tMJ disc displacement?
Internal derangements of the temporomandibular joint occur when the articular disc —the cartilage that cushions bone contact— moves out of its usual position. This is a common cause of clicking, locking and limited opening.
What symptoms are linked to tMJ disc displacement?
With disc displacement with reduction, the disc slides forward when the mouth is closed and returns on opening, often producing an audible click, sometimes with brief pain. With disc displacement without reduction, the disc stays forward and the jaw may lock with markedly limited opening.
These patterns may start after trauma, prolonged clenching, sustained posture or sudden changes in jaw function. Without care, clicks can become more frequent, locking more persistent and mouth opening more restricted.
How is tMJ disc displacement treated at Kinésica?
At Kinésica we assess opening range, jaw tracking, joint sounds and muscle involvement. We use TMJ techniques, osteopathy and gentle manual work to improve biomechanics, reduce disc irritation and restore a more functional range.
How is tMJ disc displacement assessed?
When indicated, we add jaw mobility exercises, habit education and coordination with dentistry for occlusal factors. The goal is to reduce pain, normalize opening and prevent an acute lock from becoming chronic.
When should you seek care for tMJ disc displacement?
This information is educational and does not replace medical assessment.
- Severe pain that does not improve with relative rest or worsens quickly.
- Progressive weakness, sensory changes, or difficulty walking.
- Recent trauma, fever, general malaise, or new unusual symptoms.
If these signs appear, seek prompt medical evaluation. Conditions of use and informational scope.
Approach at Kinésica
Care depends on whether the disc reduces, whether there is current locking and how long symptoms have been present.
Frequently asked questions
Why does the jaw pop or click during chewing or opening wide?
The click happens when the articular disc sits displaced forward at rest and momentarily pops back onto the condyle as the mouth opens (reducing disc displacement).
What can happen if a clicking jaw joint is left untreated over time?
The disc can eventually fail to recapture (non-reducing displacement), resulting in painful jaw locking, restricted mouth opening, and premature joint wear.
