Jaw Clicking or Popping When You Chew: When to See a Dentist

By Dr. Boris Zusin · Published August 1, 2026

A clicking or popping jaw is common enough that many people live with it for years without a second thought. Clicking or popping is actually the main sign of altered movement between the jaw's disc and condyle, and it shows up in roughly a quarter of adults — usually without pain.^[2] On its own, occasional painless clicking often doesn't need treatment. But there's a point where it's worth having looked at, and a smaller set of warning signs worth knowing about.

What's Usually Happening: Disc Displacement With Reduction

The most common cause of a distinct, sharp click during opening and closing is a condition called disc displacement with reduction. Inside the temporomandibular joint (TMJ), a small disc normally cushions the joint. In this condition, the disc sits slightly out of position at rest — usually shifted forward — and snaps ("reduces") back into place as the jaw opens, producing the click. It can show up as a single click on opening, or as a pair of clicks on both opening and closing.^[1,2,3] This pattern is usually painless. If the disc eventually stops reducing back into place, it can progress to a "closed lock" — limited opening with the jaw deviating to one side — which is one of the situations worth having evaluated sooner rather than later.

Other Possible Causes

A handful of other conditions can also produce jaw noise, and telling them apart is part of what a dental evaluation is for:

• TMJ hypermobility (subluxation): the jaw joint slides further forward than normal at wide opening, producing a pop or clunk near maximal opening, sometimes with a brief feeling of getting stuck open.^[4]
• Myofascial (muscle-based) TMD: pain and tenderness in the chewing muscles is the dominant feature here, with joint noise sometimes present alongside it rather than being the main problem.^[1,2]
• Bruxism (clenching/grinding): overloads both the muscles and the joint over time; look for worn tooth edges, ridges along the inside of the cheeks, or morning jaw stiffness.
• TMJ osteoarthritis: produces a coarser grating or crunching sound (crepitus) rather than a sharp click, and is more often paired with stiffness and a gradually shrinking range of motion.^[7,8]

Two Things That Shouldn't Wait

Almost all jaw clicking is benign, but two situations are genuine emergencies and deserve same-day medical attention rather than a routine dental visit:

• Septic arthritis of the TMJ. This is a joint infection that can cause irreversible damage within about a week if it goes untreated. Warning signs include swelling or redness in front of the ear, difficulty opening the mouth, fever, and a bite that suddenly feels different.^[9,10]
• A jaw fracture. Consider this after any trauma to the face or jaw, especially alongside a new bite misalignment or sudden jaw deviation when opening.

When It's Worth a Routine Visit

Outside of those red flags, clicking is worth having evaluated — on a normal, non-urgent timeline — when it's paired with jaw pain, soreness around the ears or temples, the jaw locking open or shut, a noticeably reduced range of motion, or a bite that has started to feel different. Isolated clicking with no pain, locking, or limited opening often doesn't even meet the formal criteria for a TMJ disorder, and usually just warrants watching rather than treating.^[6,14]

What an Evaluation Looks Like

A dental evaluation for jaw clicking typically starts with questions about the character of the sound (a sharp click versus a grating crunch), pain, any locking, how long it's been going on, and whether you clench or grind. From there, we measure how wide you can open, feel the joint and chewing muscles while you move your jaw, and check for any deviation in your bite.^[11]

Imaging usually isn't necessary for isolated, painless clicking. It becomes useful when there's crepitus, restricted or locked opening, or when first-line treatment hasn't helped — a CT scan can show bony changes consistent with osteoarthritis, and an MRI remains the most reliable way to directly see the position of the disc.^[8,12,13]

What Treatment Can Look Like

Most TMJ-related clicking and discomfort responds well to conservative, stepwise care, shown below. The diagram is an original illustration built for this post, not a reproduction of any published figure.

Reassurance that isolated clicking usually isn't a sign of a serious or worsening problem, a temporarily softer diet, avoiding wide yawning or gum chewing, warm compresses, over-the-counter anti-inflammatories, and jaw stretches or physical therapy make up the conservative first steps. For patients who clench or grind, a custom occlusal appliance is a well-supported next step^[1], and for cases where stress is clearly contributing, structured coping-focused therapy has evidence behind it as well.^[5] We'll examine your bite and jaw movement to figure out what's actually driving your symptoms before recommending anything.

When Clicking Stops: A Sign Worth Paying Attention To

Reciprocal clicking — a click on both opening and closing — is the clinical hallmark of disc displacement with reduction, and most people live with that pattern indefinitely without it ever becoming anything more.^[13,21] But for a subset of patients, the disc gradually stops reducing back into place at all. When that happens, the click typically disappears — not because the joint has improved, but because the disc is now stuck out of position full-time. This is disc displacement without reduction, commonly called a closed lock, and it shows up as a noticeably reduced, often one-sided opening, sometimes with the jaw deviating toward the affected side.^[22] Longitudinal imaging studies following these patients over time confirm that this progression — from a reducing disc to a non-reducing one — is a real, trackable pattern rather than just a theoretical concern, and ultrasound and MRI are both used to document the shift in disc position as it happens.^[18,20,22]

In practice, that means a jaw click that suddenly stops — especially if it's replaced by new stiffness or a smaller opening — is worth mentioning at your next visit even if it isn't painful. It's a different situation from a click that was never there to begin with, which is far more often benign.^[19]

Why Timing Matters If the Jaw Does Lock

If a closed lock does develop, how soon it's addressed makes a real difference to the outcome. Manual mandibular manipulation — a hands-on technique aimed at coaxing the disc back into its normal position — is a well-supported first-line treatment, but its success rate drops off sharply the longer the jaw has already been locked, as shown below.

In one study of patients with a closed lock, manipulation succeeded in restoring normal disc reduction in 92.1% of patients treated within the first month, compared with 63.8% of those treated between one and three months in, and just 28.9% of those who waited more than three months.^[23] That's the practical reason a new, persistent limitation in jaw opening is worth having evaluated promptly rather than waiting it out — the same conservative steps described above (self-care, jaw exercises, a stabilization splint, and where appropriate, manipulation or low-level laser therapy) are considerably more likely to work early than late.^[17,25]

What a Physical Therapy Program for a Locked Jaw Actually Looks Like

When manual manipulation alone isn't enough, or as part of the broader recovery afterward, structured physical therapy is a well-supported first-line option for a closed lock — and when it's combined with other conservative measures, it's been shown to produce outcomes similar to surgery for resolving lock symptoms, which is why it's typically tried well before any surgical option is considered.^[27,37] There's no single standardized protocol, but effective programs consistently combine three elements, usually alongside behavioral counseling and a stabilization or repositioning splint:

• Manual therapy. This tends to be the single highest-ranked component for both pain relief and improving how wide you can open. Joint mobilization — gentle distraction and translation techniques addressing the joint capsule — combined with intraoral and extraoral soft-tissue release, generally outperforms soft-tissue work on its own for restoring movement.^[29,31]
• Therapeutic exercise. A daily home program of controlled, tongue-depressor–assisted opening, isometric jaw-stability holds, and lateral or protrusive excursions reliably improves pain, joint sounds, and side-to-side movement, though gains in overall opening tend to be less consistent when exercise is used entirely on its own.^[33,34]
• Adjunctive modalities. Low-level laser therapy and therapeutic ultrasound have the best evidence for reducing pain and improving opening; TENS and moist heat are commonly added as well, with somewhat more modest effects.^[29,35]

Timing still matters here, the same way it does for manual manipulation: in patients rehabilitated with passive disc repositioning, a splint, and physiotherapy, how much range of motion came back depended in real part on how soon rehabilitation started after the jaw first locked.^[28] In adolescents with an acute closed lock, adding manual disc reduction and a repositioning splint to a structured PT program produced better outcomes than physical therapy alone — underscoring that these approaches work best used together rather than in isolation.^[26] A physical therapist experienced in jaw disorders can also help with the broader picture, since jaw pain often overlaps with neck posture and sleep quality.^[27] As with manipulation, escalation to a procedure like arthrocentesis or arthroscopy is generally reserved for patients whose symptoms don't respond to this conservative approach.^[36,37]
