TLDR: Clicking in ear is usually Eustachian tube dysfunction, earwax, TMJ, middle ear fluid, or — in rarer cases — a condition called middle ear myoclonus where tiny muscles in the ear spasm. Most cases aren’t serious. The ones worth acting on are clicking with pain, hearing changes, dizziness, or anything that’s been going on for weeks with no obvious trigger.
There’s something particular about a clicking sound in your ear. It’s not painful, most of the time. It’s not even constant. But it catches your attention every single time it happens, and after a while the guessing starts — what is that, why does it happen when I swallow, why is it worse at night?
Some people describe it as a soft pop. Others say it feels like something snapping inside the ear. A few get rapid crackling bursts with no warning at all. And almost everyone tries the same thing first — moving their jaw hard, swallowing, or tilting their head — to see if it stops.
Sometimes it does. Sometimes it gets worse. Here’s what’s actually behind it.
At The Hearing Centre in Singapore, our audiologists see patients with clicking in ear regularly — and the question is almost always the same. Is this serious? What’s causing it? And at what point do I need to do something about it?
What Clicking in the Ear Actually Feels Like
Before getting into causes, naming what people actually experience matters — because ear clicking isn’t one thing.
For some people it’s a pop every time they swallow or yawn. For others it’s a crackling that comes specifically when they move their jaw. A few people get rhythmic clicks that happen in bursts, with no trigger they can identify. Some feel it deep in the ear canal. Others feel it more toward the front of the face, near the jaw joint.
These differences actually point toward specific causes. Where it happens, what sets it off, whether it hurts — all of that tells your audiologist at The Hearing Centre a lot before any tests are even done.
7 Causes of Clicking in the Ear
1. Eustachian Tube Dysfunction
By far the most common cause. The Eustachian tube connects your middle ear to the back of your throat and equalises pressure. It opens briefly when you swallow or yawn — you might notice a soft pop when it does, which is completely normal.
The problem starts when that tube doesn’t open and close cleanly. Congestion, allergies, inflammation — any of these can partially block it. When pressure builds behind a blocked tube and it finally snaps open, the release creates a click or crackling sound that feels like it’s coming from inside the ear.
Eustachian tube clicking is almost always linked to swallowing or yawning. It often comes with a feeling of fullness in the ear. Flying makes it worse. A cold makes it significantly worse. And in Singapore, where people constantly move between heavily air-conditioned spaces and outdoor humidity, a lot of people find this pattern flares more frequently than it would in drier climates.
2. Earwax Buildup
Hardened earwax sitting deep in the canal presses against the canal walls and eardrum. When the jaw moves — during chewing, talking, swallowing — that wax shifts slightly and produces a crackling or clicking sensation.
This one often goes undiagnosed because earwax buildup doesn’t usually hurt. The ear just feels vaguely muffled with occasional clicking, and people either ignore it or reach for a cotton bud. Cotton buds push wax further in, compact it against the eardrum, and amplify the problem. Professional removal usually resolves the clicking immediately.
3. TMJ Disorder (Temporomandibular Joint)
The temporomandibular joint sits directly in front of the ear canal. It’s the hinge connecting your jawbone to your skull, and when it’s misaligned, inflamed, or the cartilage inside it is damaged, every jaw movement produces a click that feels like it’s coming from inside the ear rather than from the joint.
The tell with TMJ is the trigger. If the clicking in ear happens specifically when you open your mouth wide, chew, or shift your jaw sideways — that’s a jaw joint problem, not an ear problem. It often comes with tenderness in the muscles around the jaw and temple, and sometimes a grinding or popping sensation felt in the joint itself.
If you’re also experiencing pain behind the left ear on the same side as the clicking, TMJ is worth considering — the pain from jaw joint issues frequently radiates toward the back of the skull near the ear.
4. Middle Ear Myoclonus
This one is genuinely uncommon and can take a while to diagnose because most people haven’t heard of it. Middle ear myoclonus happens when the tiny muscles inside the middle ear — the stapedius and tensor tympani — go into involuntary spasm. These muscles normally protect the eardrum from loud sounds. When they twitch randomly without any acoustic trigger, they produce clicking, buzzing, or rapid crackling from inside the ear.
What makes it distinctive: the clicking tends to be rhythmic, happens without jaw movement or swallowing, and can sometimes be loud enough that the person sitting next to you might actually hear it. It often gets worse at night when surroundings go quiet. It’s not dangerous, but it’s genuinely disruptive — particularly when it interrupts sleep.
The cause isn’t fully understood. Research points toward links with noise exposure and stress. It’s rare enough that people sometimes spend months being told their ears look fine before someone considers middle ear myoclonus.
5. Fluid Behind the Eardrum
Fluid accumulating in the middle ear — from infection, blocked Eustachian tube drainage, or as a hangover from a cold — creates crackling and clicking as the eardrum moves against fluid rather than air during pressure changes.
Middle ear fluid after a cold or respiratory infection is common in both children and adults. In children in Singapore it’s particularly frequent, given how often upper respiratory illnesses circulate. The clicking here is usually accompanied by a feeling of fullness, hearing that sounds muffled, and occasionally mild discomfort. It can sound like liquid shifting when you tilt your head.
6. Ear Infections
Active ear infections produce clicking and crackling as the eardrum becomes inflamed and fluid builds behind it. Clicking in ear with pain that’s been worsening over several days is the combination that needs prompt attention rather than watchful waiting.
If you’ve been experiencing sharp pain behind the ear that comes and goes alongside the clicking, that pattern is consistent with middle ear involvement and worth getting assessed rather than hoping it settles.
7. Patulous Eustachian Tube
The opposite problem to a blocked tube — this one stays abnormally open. When the Eustachian tube doesn’t close properly, sounds from inside the body transmit through it and into the ear. Your own voice sounds hollow or too loud. You can hear your own breathing clearly. And clicking or crackling accompanies normal movements.
People with a patulous Eustachian tube usually notice that symptoms improve when they lie down and worsen when standing. It’s associated with significant weight loss, pregnancy, and prolonged dehydration. It’s less common than standard Eustachian tube dysfunction but worth knowing about, because the treatment approach is quite different.
Clicking in Ear When Swallowing
When the clicking happens specifically during swallowing — every time, reliably — Eustachian tube dysfunction is almost certainly the cause. Swallowing activates the muscles that open the tube, so if it’s blocked or inflamed, that opening motion produces an audible pop.
Occasional clicking when swallowing during a cold or after a flight is nothing to worry about. Clicking every single time you swallow, for weeks on end, with persistent ear fullness on that side — that’s worth getting properly assessed.
Clicking in Ear When Moving Your Jaw
Jaw-triggered clicking points toward TMJ disorder first, Eustachian tube dysfunction second. The distinction matters because they need different treatment.
TMJ clicking usually comes with some jaw discomfort, a sensation of grinding or catching in the joint, and tenderness in the muscles around the temple and jaw. Pure Eustachian tube clicking tends to involve more ear pressure and less jaw pain. Some people have both, which is genuinely frustrating to sort out without a proper clinical assessment.
Clicking in Ear When Lying Down
Night-time clicking is something people often don’t mention because it’s not happening when they’re in the clinic. But it’s worth flagging.
Middle ear fluid shifts position when you lie flat, producing crackling that isn’t present during the day. Middle ear myoclonus often feels more prominent at night simply because the room goes quiet and there’s less background noise masking it. Some people only notice the rhythmic clicking when trying to sleep — and end up spending a lot of time reading about conditions they can’t verify at 2am.
If you’re consistently woken by ear clicking, or find it specifically worse on one side when lying down, mention that pattern at your appointment. It changes the diagnostic picture.
Can Clicking in the Ear Affect Hearing?
The clicking itself usually doesn’t cause hearing loss. But several of the underlying causes do.
Significant earwax impaction narrows the canal and causes muffled hearing. Middle ear fluid causes conductive hearing loss that usually resolves when the fluid drains. Significant Eustachian tube dysfunction can muffle hearing on the affected side. And while middle ear myoclonus doesn’t damage hearing structurally, it can interfere with how the ear processes sound during episodes.
Clicking in ear with any hearing change — even mild muffling, even just “my ear feels blocked on that side” — is the combination that deserves a proper assessment rather than waiting. A hearing test at The Hearing Centre shows exactly where hearing stands and whether the underlying cause is affecting function.
When Clicking in Ear Is a Reason to See Someone Urgently
Most ear clicking isn’t urgent. A few situations genuinely are.
Clicking that came on at the same time as sudden stabbing pain in ear — sharp, unexpected pain alongside clicking could mean pressure injury, infection, or eardrum involvement. Don’t sit on that one.
Clicking alongside a sudden reduction in hearing on one side — this needs same-day or next-day assessment. Sudden hearing loss responds much better to treatment when caught early.
Clicking with fever, discharge from the ear, or any facial weakness — suggests active infection that may be progressing.
Rhythmic clicking loud enough for others to hear — this is middle ear myoclonus territory, not a simple mechanical issue.
Anything that’s been going on for more than two to three weeks without improvement — unlikely to settle on its own at this point, and needs a diagnosis rather than continued observation.

How Clicking in the Ear Gets Diagnosed
At The Hearing Centre, diagnosis uses a combination of methods depending on what the pattern of clicking suggests.
Otoscopy — a direct look at the ear canal and eardrum. Checks for earwax impaction, visible fluid behind the eardrum, and eardrum condition.
Tympanometry — measures eardrum movement in response to pressure changes. Very useful for identifying middle ear fluid and Eustachian tube dysfunction. A flat result on tympanometry suggests fluid or significant tube dysfunction.
Pure tone audiometry — tests hearing across different frequencies. Identifies whether the underlying cause is affecting hearing and how much.
ABR/ASSR testing — used where inner ear or auditory nerve involvement is suspected.
Treatment Options for Clicking in the Ear
There’s no single treatment for clicking in ear because the causes are genuinely different conditions. What works for Eustachian tube dysfunction won’t do anything for TMJ, and vice versa.
Eustachian tube dysfunction: Nasal decongestants or antihistamines for congestion-related cases. Nasal steroid sprays for allergy-driven ones. Swallowing, yawning, and the Valsalva manoeuvre — gently trying to blow with your mouth and nose closed — to encourage the tube to equalise. For persistent cases that don’t respond, an ENT may consider balloon dilation of the tube.
TMJ disorder: Jaw exercises from a physiotherapist or dentist. Night guards for people who grind. Anti-inflammatory pain relief. Referral to a specialist in more persistent cases.
Middle ear fluid: Often watched for a few weeks because many cases clear spontaneously. If fluid stays, an ENT may consider ventilation tubes — grommets — to allow drainage.
Middle ear myoclonus: Muscle relaxants or anticonvulsants for moderate cases. Botox injections into the middle ear muscles for more severe ones. Surgery in the most treatment-resistant cases. Most people get some relief with treatment, though it sometimes takes a few attempts to find what works.
Patulous Eustachian tube: Staying hydrated, avoiding diuretics, saline nasal drops. Bulking agents or surgical management through ENT for persistent cases.
Home Remedies Worth Trying First
For mild, occasional clicking with no pain and no hearing changes, a few things are worth trying before booking an appointment.
Swallowing repeatedly, yawning, or chewing gum opens the Eustachian tube and often clears mild pressure-related clicking straight away.
The Valsalva manoeuvre — pinch your nose, close your mouth, and gently try to breathe out — pushes air through the Eustachian tube and can equalise pressure. Don’t do this if you have an active ear infection.
Steam inhalation loosens congestion around the Eustachian tube when clicking is linked to a cold or sinusitis.
Warm compress against the outer ear soothes mild inflammation and can help fluid in the middle ear start moving.
Gentle jaw massage and stretching — for clicking that tracks directly with jaw movement — can reduce tension around the TMJ and ease the frequency of clicks.
What not to do: cotton buds inside the ear canal. If wax is involved, you’ll compact it further. If wax isn’t involved, you’ll scratch the skin and create a new problem.
Clicking in the Ear and Hearing Aids
For hearing aid users, clicking sounds sometimes come from the device rather than the ear itself.
A dome or earmold that doesn’t fit correctly creates a small gap. When the jaw moves or there’s air movement near the microphone, that gap produces feedback or crackling that can be mistaken for an ear problem. This is a fit and programming issue — straightforward to fix at an adjustment appointment.
If you’ve started hearing clicking since getting hearing aids, the first thing to do is work out whether the sound is coming from the device or from the ear. Sometimes it’s both. Sometimes replacing the dome sorts it entirely. Our audiologists at The Hearing Centre check this as a matter of course.
When to Come to The Hearing Centre
Clicking in ear for more than two weeks without an obvious cause — come in. Any hearing reduction alongside the clicking, even if it seems mild — come in. Persistent pain alongside the clicking, whether it’s a dull ache or something sharper — come in.
If the pain pattern includes sharp pain behind the ear that comes and goes on the same side as your clicking, that’s worth an assessment rather than monitoring at home.
Frequently Asked Questions
Most of the time, no. Eustachian tube dysfunction, mild earwax, and TMJ-related clicking are benign and fixable. Clicking with pain, hearing loss, or rhythmic bursts happening without any trigger is the combination to take more seriously.
Almost always Eustachian tube dysfunction. The muscles that open the tube activate when you swallow — if the tube is blocked or inflamed, that opening motion produces an audible click rather than a silent equalisation.
Yes. Hardened wax pressing against the canal walls or eardrum creates crackling and clicking when the jaw moves. Professional removal resolves it, often immediately. Cotton buds will not.
An uncommon condition where the tiny muscles inside the middle ear spasm involuntarily, producing rhythmic clicking or buzzing without any jaw movement or swallowing trigger. Sometimes people nearby can hear it too. It’s treatable but needs specialist diagnosis.
Yes. The jaw joint sits directly in front of the ear canal — misalignment or cartilage damage produces clicking that feels like it’s inside the ear rather than in the jaw.
When it’s caused by a cold or sinus infection, usually one to two weeks as congestion clears. Clicking persisting past three weeks needs assessment — it won’t always resolve on its own.
The clicking itself generally doesn’t. But several underlying causes do — earwax impaction, middle ear fluid, and Eustachian tube dysfunction all affect hearing to varying degrees.
Starting with an audiologist at The Hearing Centre makes sense. We test the ear, identify the cause, and manage what we can. If something needs surgical management — balloon dilation, grommets, myoclonus surgery — we refer to ENT with the clinical picture already documented.
Same causes as daytime clicking, but more noticeable when surroundings go quiet. Middle ear myoclonus specifically tends to feel worse at night. If it’s waking you up or making sleep difficult, that’s worth mentioning when you come in.
They’re related. Middle ear myoclonus is sometimes classified as a type of objective tinnitus. Some people with Eustachian tube dysfunction also experience ringing or hissing alongside the clicking. They’re different experiences but can overlap in the same person.
