The most common sign of earwax buildup is a feeling of fullness or pressure in one ear, often paired with muffled hearing. About 1 in 5 Americans over age 12 has enough impacted earwax to partially or fully block the ear canal, and that number jumps to nearly 1 in 3 adults over 70. Most people with buildup notice it gradually, not all at once, which makes it easy to dismiss or confuse with other ear problems.
Symptoms That Point to Earwax Buildup
Earwax buildup produces a recognizable cluster of symptoms. The hallmark is a plugged or full sensation in the ear, as if you’re wearing an earplug on one side. Beyond that, you may notice:
- Muffled hearing that tends to worsen over time rather than appearing suddenly
- Earache or a dull pressure-like pain
- Itchiness inside the ear canal
- Ringing or buzzing (tinnitus) in the affected ear
- Dizziness or mild balance problems
- Odor or discharge from the ear
You don’t need all of these at once. Many people only experience the fullness and hearing changes. The ringing and dizziness happen because impacted wax can press against the eardrum or create pressure changes in the ear canal, interfering with the signals your inner ear sends to your brain about sound and balance.
How It Differs From an Ear Infection
Because earwax buildup and ear infections share symptoms like pain, fullness, and reduced hearing, it’s worth knowing how to tell them apart. The key distinction: earwax buildup does not cause fever or symptoms of an upper respiratory infection. If you’ve recently had a cold, sore throat, or congestion, and now your ear hurts, that pattern points more toward infection than wax. Ear infections also tend to produce sharper, more intense pain that worsens quickly, while wax-related discomfort is usually duller and builds gradually over days or weeks.
Discharge can appear with both conditions, but infected ears often produce pus-like fluid, while waxy buildup produces a darker, thicker material that looks and smells like old earwax.
Why Some People Get Buildup More Than Others
Your earwax type is genetically determined. Humans produce one of two types: wet earwax (sticky and honey-colored to dark brown) or dry earwax (flaky and gray or tan). A single gene variant controls which type you make. Wet earwax is more common in people of European and African descent, while dry earwax is more common in East Asian populations. Wet earwax is stickier, which can make it more prone to accumulating, though both types can cause impaction.
Several other factors increase your risk:
- Cotton swab use. In a survey of regular cotton swab users, about 10.5% reported worsened earwax blockage as a direct result. Cotton swabs push wax deeper into the canal rather than removing it. They’re also the most frequent cause of traumatic eardrum perforations treated in emergency departments.
- Earbuds, hearing aids, and earplugs. Anything you insert into your ear canal regularly can block the natural outward migration of wax.
- Narrow or curved ear canals. Some people are born with canal shapes that make it harder for wax to exit on its own.
- Age. Earwax gets drier and harder as you get older, and the ear canal’s self-cleaning mechanism slows down. Prevalence of impaction reaches 32.4% in adults 70 and older.
- Overproduction. Some people simply produce more cerumen than others, often without a clear cause.
What You Can See (and What You Can’t)
You can sometimes spot buildup by looking at the outer part of the ear canal. If you see dark, waxy material near the opening of the ear, that’s a reasonable clue. But the blockage that causes symptoms usually sits deeper in the canal, where you can’t see it without a proper instrument. A healthcare provider uses an otoscope, a handheld light with a magnifying lens, to look directly at the canal and eardrum. Impacted wax ranges in color from light yellow to nearly black, and its texture can be soft and oily or hard and compacted. Harder wax tends to contain more dead skin cells and is more likely to harbor bacteria or fungi.
In some cases, the wax completely blocks the view of the eardrum. When that happens, a provider can’t assess the rest of the ear until the wax is removed. If a hearing test or pressure test (tympanometry) is attempted with a blocked canal, the results will be unreliable because the instrument reads the wax as an abnormally small canal volume rather than measuring eardrum function.
A Simple Self-Check
You can’t definitively diagnose earwax impaction at home, but a few quick checks can tell you whether buildup is the likely cause of your symptoms. Gently tug on your outer ear and press on the small flap (tragus) in front of the ear canal. If this produces significant pain, an infection of the outer ear canal is more likely than simple wax buildup. If it doesn’t hurt much but you still have that plugged feeling, wax is a strong possibility.
Try this as well: cup your hand over the affected ear and press gently, then release. If your hearing briefly changes or you feel a shift in pressure, something is obstructing the canal. Cover the unaffected ear with a finger and listen to how sounds register on the blocked side. A noticeable difference in volume or clarity between the two ears supports the idea of a physical blockage.
What Happens if You Leave It
Earwax buildup isn’t dangerous in most cases, but it doesn’t tend to resolve on its own once the canal is significantly blocked. The hearing loss will persist and can worsen as more wax accumulates. Persistent blockage can also trap moisture behind the wax plug, creating conditions where bacteria and fungi thrive. This can lead to an outer ear infection (otitis externa), which brings sharper pain, swelling, and sometimes fever.
In older adults, untreated wax impaction is a common and underrecognized cause of hearing difficulty that gets mistaken for age-related hearing loss. Removing the wax can produce an immediate and sometimes dramatic improvement in hearing.
Safe Ways to Address It
If your symptoms are mild, over-the-counter earwax softening drops (typically mineral oil, saline, or hydrogen peroxide-based) can help. You tilt your head, place a few drops in the affected ear, wait several minutes, then let the liquid drain out. Doing this for a few consecutive days can soften the wax enough for it to work its way out naturally. A bulb syringe with warm (not hot) water can gently flush loosened wax after softening.
If drops and gentle rinsing don’t work after a week, or if you have significant hearing loss, pain, or dizziness, a provider can remove the wax more thoroughly. The process is quick and usually involves irrigation with a specialized syringe or manual removal with a small curved instrument under direct visualization. Most people hear noticeably better within seconds of removal.
What you should avoid: cotton swabs, bobby pins, ear candles, or any rigid object inserted into the canal. Among cotton swab users who reported complications, over 21% experienced ear discomfort, nearly 5% developed infections, and about 2.6% had bleeding. These tools consistently push wax deeper and risk puncturing the eardrum.
