Jaw Clicking vs Popping: What the Difference Means

Reviewed by Dr. Erica Zolnierczyk, DMD · Inspire Dental Wellness, Orland Park, IL

Most people have noticed a click or pop in their jaw at some point — opening wide, yawning, taking a big bite. The question patients ask is whether it matters and what to do about it. The honest answer is that it depends — on what kind of sound, when it happens, and what else is going on in the joint.

The anatomy quickly

The temporomandibular joint (TMJ) connects the lower jaw to the skull on each side, just in front of the ear. Inside the joint sits a small fibrocartilage disc that cushions movement and slides forward and back as you open and close. Joint sounds typically come from this disc moving in or out of position relative to the jaw bone (condyle).

Clicking vs popping — what’s the difference?

Clicking

Clicking is typically a softer, single sound. Patients describe it as “click,” “tick,” or sometimes “snap.” Often it happens at a specific point in opening or closing — for example, mid-way through opening on one side. The mechanism is usually disc displacement with reduction: the disc has slipped slightly out of position at rest, and as the jaw opens it “clicks” back into proper position.

A single, painless click that’s been there for years and isn’t accompanied by other symptoms is often clinically silent. Many patients have it and never need treatment.

Popping

Popping is louder, sharper, sometimes accompanied by a sensation of the jaw “catching” or “shifting.” It can occur during opening, closing, or chewing. The mechanism varies — more advanced disc displacement, joint loading from grinding, or in some cases osteoarthritic changes in the joint surfaces.

Popping is more likely to indicate progressive joint mechanics issues. A popping joint with pain, limited motion, or recent onset warrants evaluation.

Other sounds worth flagging

• Crepitus — a grating, sandy, or “rice krispies” sound. Usually indicates arthritic changes in the joint surfaces. Worth evaluating.
• Grinding sound with movement — similar to crepitus, suggests bone-on-bone or significant disc damage.
• Sudden new pop after trauma, wide yawning, or extended dental procedures — could indicate a recent disc displacement.

When to get the sound evaluated

A jaw sound by itself, in isolation, with no other symptoms, isn’t necessarily an emergency. The sound becomes more concerning when accompanied by:

• Pain — in the joint, jaw muscles, ear, temple, or face
• Limited opening — can’t open as wide as you used to, or “closing locking” where the jaw gets stuck closed
• Catching or locking — jaw briefly gets stuck during opening or closing
• Asymmetric opening — jaw deviates to one side as it opens
• Recurrent or worsening pattern — sounds becoming more frequent, louder, or more painful over time
• Headaches — particularly tension-pattern headaches in the temples (see TMJ headaches explained)
• Morning soreness — suggests nighttime grinding/clenching
• Difficulty chewing — particularly tough or chewy foods

Any of these alongside clicking or popping is a reasonable trigger for evaluation. Sound alone, with no other signs, can usually be monitored.

What evaluation looks like

At Inspire Dental Wellness, evaluation for joint sounds includes:

• Joint Vibration Analysis (BioJVA) — a 10-second non-invasive test that quantifies joint sounds and patterns. The same click sounds the same to your ear regardless of cause; BioJVA differentiates benign mechanics from concerning ones.
• Range of motion testing — opening width (normal is around 40-55mm), deviation patterns, end-feel
• Manual palpation of the joint and surrounding muscles
• Bite analysis — wear patterns, grinding/clenching evidence
• Imaging if indicated — usually only when other findings warrant it

The goal is to characterize what’s actually happening in the joint, not just describe the sound. From there we discuss whether monitoring, conservative treatment, or specialized referral fits the case.

What treatment looks like (when it’s needed)

For mild-to-moderate disc displacement with symptoms:

• Bite splint to reduce nighttime joint loading
• Address bruxism and underlying drivers (often airway-related — see airway dentistry)
• Physical therapy for the surrounding muscles and cervical spine
• Soft-food diet during flare periods
• Avoid wide opening (gum, big bites, dental procedures with extended opening)
• Stress management for daytime clenching

For more advanced joint issues (locked joint, severe limited motion, significant osteoarthritis), specialist referral to oral/maxillofacial surgery or a TMJ specialist may be warranted. We refer when the picture warrants it.

What NOT to do

• Don’t crack your jaw repeatedly. Some patients try to “reset” their jaw by intentionally clicking or popping it. This typically worsens joint mechanics over time.
• Don’t chew gum on a clicking joint. Sustained chewing increases joint loading and can accelerate progression.
• Don’t ignore pain. Pain alongside sounds is the signal to get evaluated, not the signal to “tough it out.”
• Don’t get major irreversible dental work done (extractions, crowns, bridges, orthodontics) without a TMJ evaluation if you have significant symptoms — bite changes can affect joint mechanics.

Frequently asked questions

My jaw has clicked for years with no pain. Is that fine?

Often yes, particularly if the click is unchanged over time and there are no other symptoms. We’d still document it during a regular dental exam, but it’s not necessarily a treatment trigger.

Can a clicking jaw lead to arthritis later?

Some clicking patterns do progress over years, particularly when accompanied by chronic bruxism or unresolved joint loading. Some don’t progress at all. The accompanying signs (pain, motion changes, frequency change) are better predictors than the click itself.

Should I get my clicking jaw evaluated by a dentist or an oral surgeon?

An airway-focused dentist is a good first stop because TMJ issues often have airway and bite drivers that are within general dental scope. Oral/maxillofacial surgery referral is for cases where conservative treatment isn’t sufficient or where there’s significant joint pathology.

Will a nightguard stop the clicking?

It can reduce it for some patients, particularly if the click is being driven by nighttime joint loading from grinding. Nightguards don’t directly fix disc displacement, but they reduce ongoing aggravation and protect the joint and teeth.

Can clicking be caused by my bite?

Bite issues can contribute. An asymmetric or unstable bite loads the joints unevenly. Functional orthodontics or bite adjustment can be part of the picture for some patients — see functional orthodontics.

Where to start

If your jaw clicks or pops with any of the warning signs above (pain, limited motion, locking, headaches, morning soreness), evaluation is worth doing. Schedule a consultation or call (708) 460-6699.
