Clicking and Popping TMJ Symptoms

A clicking or popping sound from the jaw is one of the most commonly reported TMJ symptoms. While an occasional click without pain may not require treatment, these sounds are worth paying attention to, as they can indicate that something within the joint is not moving as it should.

Why Clicking Occurs

In many cases, clicking occurs because the cartilage disc inside the joint has shifted out of its normal position. As the condyle (the rounded end of the lower jaw) moves during opening or closing, it catches and then passes over the edge of the displaced disc, producing the characteristic sound.

When Clicking Warrants Evaluation

• Clicking accompanied by pain, even mild discomfort
• A click that changes in character, becomes louder, or begins to limit mouth opening
• When a click disappears and is replaced by difficulty opening the mouth fully (acute closed lock), this warrants prompt attention

Acute Jaw Locks

Acute closed lock occurs when a displaced disc fully blocks jaw movement. The mouth cannot open normally, and attempting to do so causes pain. This situation should be assessed as soon as possible.

Acute open lock, the less common opposite, occurs when the jaw becomes stuck in the open position and cannot close without assistance. This also requires prompt care.

Treatment Considerations

Not every clicking jaw requires active treatment. The appropriate course of action depends on a clinical assessment. If you are experiencing jaw sounds along with any pain or limitation, we encourage you to book an exam today.
