Yes, earwax can cause hearing loss. When enough wax builds up to fully or partially block the ear canal, it prevents sound waves from reaching the eardrum, resulting in what’s called conductive hearing loss. About 19% of people age 12 and older have some degree of earwax impaction, and that number climbs to 32% in people over 70.
The good news: hearing loss from earwax is almost always temporary. Once the blockage is removed, hearing typically returns to normal.
How Earwax Blocks Sound
Your ear canal is a narrow tube leading to the eardrum. Sound travels down this tube as vibrations in the air, hits the eardrum, and gets converted into signals your brain interprets as sound. When a plug of hardened or compacted wax fills enough of that tube, it either blocks sound waves entirely or presses directly against the eardrum so it can’t vibrate properly. Either way, sounds become muffled or faint.
This type of hearing loss is mechanical, not nerve damage. The inner ear and auditory nerve are still working fine. The problem is purely a physical obstruction, like putting a cork in a funnel.
Symptoms Beyond Muffled Hearing
Hearing loss is the symptom most people notice first, but impacted earwax can cause a range of other problems:
- Ear fullness, a sensation of pressure or stuffiness in one or both ears
- Tinnitus, a ringing, buzzing, or humming sound that isn’t coming from outside
- Earache or a dull, persistent pain
- Dizziness, since the ear canal sits close to the balance organs of the inner ear
- Itching inside the ear
- Odor or discharge, especially if the blockage has been there a while or an infection develops
These symptoms can show up in one ear or both. They tend to develop gradually as wax accumulates over weeks or months, which is why many people don’t connect the dots right away.
Who Gets Earwax Buildup
Some people are far more prone to impaction than others. Regular cotton swab users top the list, because swabs tend to push wax deeper into the canal rather than pulling it out. People who wear hearing aids or earplugs frequently are also at higher risk, since these devices block the ear’s natural self-cleaning process and compress wax against the canal walls. Narrow ear canals and excessive ear hair can trap wax before it has a chance to migrate out on its own.
Older adults are especially vulnerable. Beyond the 32% impaction rate in people over 70, age-related changes in earwax consistency (it becomes drier and harder) make natural clearance less effective. For someone who already has mild age-related hearing loss, even a partial wax blockage can push their hearing below a functional threshold, making the impact feel more dramatic.
Why Cotton Swabs Make Things Worse
Cotton swabs are the single most common cause of self-inflicted earwax impaction. In one survey of regular swab users, about 10.5% reported worsened wax blockage and 9.2% reported hearing loss or muffled hearing as a direct result. Overall, nearly a third of users reported some kind of complication.
The risks go beyond just pushing wax deeper. Swabs can scratch the delicate skin of the ear canal, leading to irritation and infection. In more serious cases, they can puncture the eardrum. Research has identified cotton swab use as the most frequent cause of traumatic eardrum perforations seen in emergency departments. A perforated eardrum can cause longer-term conductive hearing loss and increases the risk of middle ear infections.
Every cotton swab package carries a warning label: “Do not insert swab into ear canal.” That warning exists for good reason.
Over-the-Counter Ear Drops
Ear drops designed to soften wax are the most accessible first-line treatment. These come in oil-based and non-oil-based formulas, and research shows that no single type of drop outperforms any other. In clinical studies, using any type of active ear drop for five days led to complete wax clearance in about 22% of ears, compared to 5% clearance with no treatment at all.
That 22% clearance rate might sound low, but drops serve a dual purpose. Even when they don’t fully dissolve a blockage on their own, they soften the wax enough to make professional removal easier and more comfortable. Interestingly, plain water or saline performed about as well as specialized ear drop products in head-to-head comparisons. Side effects across all studies were mild, limited to occasional discomfort or irritation, with no serious adverse events reported.
To use ear drops, you typically tilt your head so the affected ear faces up, place the recommended number of drops inside, and stay in that position for a few minutes. Repeating this over several days gives the drops time to penetrate hardened wax.
Professional Removal Options
When drops alone don’t clear the blockage, a healthcare provider can remove wax using one of two main approaches: irrigation or manual removal.
Irrigation uses a controlled flow of low-pressure warm water to flush wax out of the canal. It’s quick, widely available, and generally well tolerated. Complications like eardrum perforation are rare, estimated at roughly 1 in 1,000 procedures. Irrigation isn’t appropriate for everyone. If you have a perforated eardrum, ear tubes, a history of ear surgery, an active infection, or only one functioning ear, your provider will use a different method.
Manual removal, often done with microsuction, involves a clinician using a small vacuum tip or specialized instruments under direct visualization to pull wax out. This is the preferred technique in specialist settings because the provider can see exactly what they’re doing throughout the process. Some patients find microsuction louder or more uncomfortable than irrigation, while others prefer it because it’s less messy. Minor discomfort and occasional small amounts of bleeding have been reported, but serious complications are uncommon.
When patients who had experienced both methods were surveyed, more than two-thirds had no strong preference between the two. Your provider will recommend the method that best fits your ear anatomy and medical history.
Preventing Future Blockages
Your ears are designed to clean themselves. The skin of the ear canal slowly migrates outward, carrying old wax with it. Chewing and jaw movement help push wax toward the ear opening, where it dries and falls out or washes away in the shower. For most people, leaving ears alone is the best prevention strategy.
If you’re prone to recurrent impaction, using softening drops once or twice a month can help keep wax from hardening and building up. Gently wiping the outer ear with a damp cloth after a shower removes any wax that has already worked its way out. If you wear hearing aids, cleaning the devices regularly and having your ears checked for wax buildup at routine appointments can prevent blockages from sneaking up on you.
