Why your ear pops
The middle ear is an air-filled space behind the eardrum. The Eustachian tube links it to the back of the nose and normally opens briefly when you swallow, yawn or chew, letting air in and out so pressure stays equal on both sides of the eardrum. When the tube opens, you may hear or feel a pop, click, crackle or a “bubble” sound. This is normal and often becomes more noticeable when the tube is swollen or the middle ear contains fluid. See crackling in ear and Eustachian tube dysfunction.
Common causes
- Colds, allergies and sinus problems, which swell the lining of the Eustachian tube. See sinus and ear pressure.
- Eustachian tube dysfunction (the tube does not open or close properly).
- Fluid behind the eardrum (serous otitis media), which makes bubbling or crackling sounds. See fluid in the ear.
- Earwax pressed against the eardrum. See ear wax removal at home.
- Temporomandibular joint (TMJ) problems, where jaw movement clicks near the ear. See jaw clicking when chewing.
- Altitude, flying, diving or driving up mountains.
- Middle ear infection and recovering from one.
- Patulous Eustachian tube, where the tube stays open, causing autophony and breathing sounds, often after weight loss.
- Middle ear myoclonus, rhythmic clicking from tiny muscle spasms (rare).
- Hypersensitivity or anxiety that makes you notice normal sounds.
What the sound can tell you
- Single pop on swallowing or yawning: normal tube opening.
- Bubbling, crackling or “Rice Krispies” sounds with a blocked feeling: fluid or mucus in the middle ear.
- Clicking when chewing or opening the mouth: jaw joint.
- Rhythmic clicking or thumping that does not depend on swallowing: muscle spasm (myoclonus) or pulsatile tinnitus. See heartbeat in ear.
- Sound of your own voice and breathing: patulous Eustachian tube.
- Popping after a flight that does not clear: barotrauma.
- Duration, triggers and associated symptoms help the clinician decide.
Home relief
- Swallow, yawn or chew gum to open the tubes.
- Try gentle autoinflation: pinch your nose, close your mouth and blow gently (not forcefully) until you feel a soft pop.
- Use a saline nasal spray or rinse to reduce congestion. See neti pot sinus rinse.
- Use a steroid nasal spray or an antihistamine if allergy contributes.
- Sip water, stay hydrated and avoid smoke.
- Warm compress over the ear for comfort.
- Relax the jaw: avoid chewing gum and tough foods if the jaw clicks.
- Avoid inserting objects into the ear.
Flying, diving and altitude
Pressure changes outpace the Eustachian tube, causing popping and blockage. During descent, swallow, yawn, chew gum or use gentle autoinflation every minute or so. Avoid sleeping through descent, and use a decongestant spray shortly before landing only if appropriate for you. Do not fly or dive with a bad cold or congestion if possible. Persistent blockage after a flight deserves review. See ear won’t pop.
Medical treatment
- Treat underlying allergy, rhinitis or sinus disease with nasal steroid sprays, antihistamines or saline.
- Watchful waiting for fluid after a cold, with hearing tests if it persists beyond 3 months.
- Antibiotics only for acute bacterial infection.
- Grommets (ear tubes) for persistent fluid with hearing loss.
- Balloon dilation of the Eustachian tube in selected chronic cases.
- Jaw treatment: bite splint, physiotherapy and stress management for TMJ disorders.
- Reassurance and sound therapy for myoclonus and sensitivity; botulinum toxin is rarely needed.
Red flags
- Sudden hearing loss in one ear. See sudden hearing loss.
- Severe ear pain, fever or discharge.
- Dizziness or vertigo, facial weakness.
- Swelling, redness or pain behind the ear.
- One-sided symptoms lasting more than 4–6 weeks in an adult, particularly in smokers.
- Popping after a head injury.
- Persistent hearing loss or tinnitus.
When to see a doctor
- Popping with a blocked feeling lasting more than 2–3 weeks.
- Popping accompanied by hearing loss, tinnitus or dizziness.
- Pain, discharge or fever.
- Frequent flying with persistent ear problems.
- A child with popping, speech delay or inattention.
- Constant clicking unrelated to swallowing.
- Any of the red flags above.
Three common situations
A cold followed by crackling and popping when swallowing: usually Eustachian tube swelling; saline, time and swallowing help.
Popping near the ear when chewing with jaw clicking: think TMJ; try a soft diet and see a clinician.
A smoker with popping and fullness in one ear for two months: needs an ENT examination.
Key points to remember
A popping sound in the ear is usually the Eustachian tube working, often noticeable with colds, allergies, fluid or jaw issues. Swallow, yawn, rinse your nose and treat the cause. See a doctor for pain, hearing loss or persistence. Our ENT team can examine your ears.

Questions about a popping sound in the ear
These answers are general information and do not replace an examination or individual medical advice.
Why does my ear make a popping sound?
Usually the Eustachian tube opening to equalise pressure, often with congestion, fluid or jaw joint movement.
What is a bubble-popping noise in the ear?
Often fluid or mucus in the middle ear moving as the tube opens.
Is a popping ear serious?
Rarely; it is a concern if it comes with pain, hearing loss, dizziness or lasts weeks.
How do I stop my ear popping?
Treat congestion, swallow or chew gum, use saline and seek advice if it persists.
Can TMJ cause popping in the ear?
Yes, the jaw joint sits right in front of the ear canal.
When should I see an ENT?
If it lasts more than 2–3 weeks or there is hearing loss, pain or discharge.
