Key Points
- TMJ clicking and popping is common at every adult age — a 2025 CBCT study found bony changes in nearly two-thirds of healthy young adults aged 18 to 30.
- Jaw sounds come mainly from the cartilage disc shifting position during movement, not simple joint wear.
- Counterintuitively, some research finds joint sounds actually decrease once real degeneration sets in, because a rougher, less mobile joint has less to click.
Short answer: usually a disc-position issue, not an aging joint — and the data suggests this is at least as much a younger-adult phenomenon as an older one. If your jaw clicks or pops when you chew, yawn, or open wide, it feels like it should be a straightforward wear-and-tear story. The actual research on the temporomandibular joint (TMJ) complicates that assumption in a genuinely interesting way.
What's Actually Making the Sound?
The TMJ has a small cartilage disc sitting between the jawbone (mandible) and skull that normally moves in sync with the jaw as it opens and closes. In many people, that disc sits slightly out of position and snaps back into place partway through the movement — this is the most common source of a jaw click, and it's technically called disc displacement with reduction. A large multi-center database study found TMJ clicking was one of the most frequent complaints among patients presenting with jaw disorders, alongside pain and muscle tension, with clicking sounds present in roughly 60% of the diagnosed cases in that dataset — and the average age in that dataset was under 40.
Does This Actually Get More Common With Age?
Not in the straightforward way you'd expect. A 2025 study using cone-beam CT imaging in a consecutive sample of adults aged 18 to 30 — all without diagnosed TMJ disorders — found bony alterations on at least one side of the jaw joint in about 64% of scans. That's a strikingly high rate of structural change in a group most people would assume has "young," undamaged joints. Separately, a study correlating clinical symptoms with imaging found that the presence of acoustic symptoms like clicking was actually lower in joints with more advanced degenerative changes — the reasoning being that as joint mobility decreases and the disc becomes less mobile, there's less dynamic movement available to produce a sound in the first place. That's the honest, counterintuitive finding here: a completely silent jaw doesn't necessarily mean a healthier one, and a clicky jaw doesn't necessarily mean a more damaged one.
What Does Predict Real Joint Damage, More Reliably Than Sound Alone?
A systematic review and meta-analysis of TMJ patients with confirmed disc displacement found degenerative joint disease was common in that specific population, but the review pooled data heavily skewed toward symptomatic patients already seeking care — meaning it describes what happens after disc displacement has caused problems, not what a random clicking jaw predicts on its own. The clinical findings that track more reliably with actual joint disease are pain with jaw movement, a jaw that gets stuck open or closed (locking), restricted range of motion, and clicking accompanied by grinding or crunching (crepitus) rather than a clean pop. Imaging studies that combine MRI findings with clinical symptoms have found that structural changes like disc thinning and joint effusion (fluid buildup) correlate more consistently with reported pain than with the presence or loudness of clicking alone — reinforcing that sound and structural status are measuring somewhat different things, much like the pattern seen in other joints throughout the body, from the knee to the knuckle.
What Can Actually Help
For clicking alone, without pain or locking, most clinical guidance is conservative: avoiding wide yawns and hard, chewy foods during flare-ups, managing clenching or grinding habits (often worse during stress or sleep), and jaw-relaxation exercises. A soft-food diet during flare-ups and warm compresses over the jaw muscles are also commonly recommended as low-risk first steps before considering anything more involved. Persistent pain, a jaw that locks, or a significant change in your bite is when it's worth seeing a dentist or oral-maxillofacial specialist rather than managing it alone, since those symptoms point toward the disc displacement progressing rather than staying in its current, reducing pattern. The jaw joint isn't the only one with a noise-versus-damage disconnect — the same "sound doesn't equal severity" pattern shows up in our piece on why joints crack and pop more with age, and morning jaw tightness specifically overlaps with the broader stiffness pattern covered in why you’re stiff in the morning.
Frequently Asked Questions
Is a clicking jaw a sign I'm developing arthritis in my face?
Not necessarily. Clicking most often comes from a mobile disc snapping into position, which is mechanically different from the cartilage-surface changes seen in true joint osteoarthritis, and research shows clicking is actually common in people with no TMJ diagnosis at all.
Why did my jaw suddenly start popping when it never did before?
New onset can follow a period of increased clenching or grinding (often stress-related), a dental procedure that changed your bite temporarily, or simply the disc shifting position — it doesn't necessarily indicate new joint damage.
Should I be worried that a young adult's CBCT scan showed bony changes in 64% of cases?
It's a reminder that TMJ imaging findings are common in the general population and don't always cause symptoms — a finding on a scan is not the same as a clinical problem. The same logic applies at any age.
When does jaw clicking need a dentist visit?
When it's joined by pain, a jaw that locks open or shut, a noticeably reduced ability to open your mouth, or a bite that suddenly feels different — those combinations point toward something beyond simple disc clicking.

Why we formulated NAD+ Restore
Joint comfort and connective tissue function both draw on the same cellular energy and repair systems that shift as you age. NAD+ Restore is built around ingredients studied for their role in supporting cellular energy pathways — we keep the formulation philosophy-first here because our formulation is currently being refined, and we would rather describe what we are trying to accomplish than list specifics that may change.
It comes with a 60-day money-back guarantee — long enough to actually evaluate it the way the research says you should.
Learn more about NAD+ Restore →The Bottom Line
A clicking or popping jaw is usually the TMJ's cartilage disc shifting position during movement — a mechanical pattern found across adult ages, including surprisingly often in people in their 20s and 30s with no diagnosed jaw disorder. It isn't a reliable stand-in for joint damage on its own, and some research suggests advanced degeneration can actually reduce audible clicking as the joint loses mobility. Pain, locking, and restricted opening are the signals that warrant an actual evaluation.
