Impacted ear wax is a buildup of earwax that causes symptoms like muffled hearing, ear pain, or a feeling of fullness, or that blocks a doctor’s view of your eardrum. The blockage doesn’t have to be complete to count as impaction. It’s surprisingly common, affecting an estimated 19% to 65% of adults over 65, and roughly one in four nursing home residents.
How Earwax Normally Works
Your ear canal has a built-in cleaning system. Glands in the outer third of the canal produce cerumen (the clinical name for earwax), which traps dust, dead skin cells, and debris. Jaw movement from talking and chewing gradually pushes the wax outward toward the opening of your ear, where it dries up and falls out on its own. Most people never need to think about it.
Impaction happens when this conveyor belt breaks down. Wax gets pushed deeper than the canal can clear, or the body produces more wax than the system can handle, or the shape of the canal slows everything down.
What Causes Wax to Build Up
The single most common cause is pushing objects into the ear canal. Cotton swabs, bobby pins, and even fingertips compress wax deeper with each pass, packing it tightly against the eardrum instead of removing it. Anything you insert past the outer edge of your ear canal works against the natural outward flow.
Hearing aids and earplugs are another major contributor. They physically block the exit route for wax and can stimulate the glands to produce more of it. People who wear hearing aids daily often deal with recurring impaction for this reason. Narrow or unusually curved ear canals, excessive hair growth in the canal, and skin conditions like eczema can also slow wax migration. Older adults produce drier, harder wax that doesn’t move as easily, which is a key reason impaction rates climb with age. In one hospital study, 35% of patients over 65 admitted to general wards had wax blocking the view of at least one eardrum.
Symptoms of Impacted Ear Wax
The most recognizable symptom is a gradual decline in hearing, often in just one ear. Because it happens slowly, people sometimes don’t notice until the blockage is significant. Other common symptoms include:
- Fullness or pressure in the affected ear
- Earache ranging from dull discomfort to sharp pain
- Tinnitus (ringing, buzzing, or humming sounds)
- Itchiness inside the ear canal
- Dizziness or a sense of imbalance
- Discharge or odor from the ear
Hearing loss from impaction is typically reversible once the wax is removed, but it can worsen over time if left alone. The dizziness and tinnitus usually resolve too, though they can be alarming when they first appear.
What You Can Try at Home
For mild buildup without severe pain, discharge, or dizziness, over-the-counter ear drops can soften the wax enough for it to work its way out naturally. The most widely available option contains 6.5% carbamide peroxide, which foams gently inside the canal to break up hardened wax. The typical routine is 5 to 10 drops in the affected ear, twice daily, for up to four days. You tilt your head to the side, let the drops sit for several minutes, then allow them to drain.
Mineral oil, olive oil, and saline drops work through a simpler mechanism: they soften and lubricate the wax so the ear’s natural clearing process can resume. These are often recommended as a first step, and some providers suggest using them regularly if you’re prone to buildup. After a few days of softening drops, remaining loose wax can sometimes be flushed out with warm water and a soft rubber bulb syringe.
Skip the drops entirely if you have ear pain, drainage, a history of eardrum perforation, or recent ear surgery. In those situations, putting liquid into the canal can cause more harm than the wax itself.
Professional Removal Options
When home treatment doesn’t work, or when the impaction is severe, a clinician can remove the wax in one visit using a few different techniques.
Manual Removal (Curettage)
A provider uses a small, curved instrument called a curette to scoop wax out under direct visualization, often with a headlamp or microscope. This is the most controlled method and works well for firm, dry wax that won’t respond to drops.
Microsuction
A thin suction tip removes wax while the provider watches through a microscope or magnifying lens in real time. It doesn’t use water, which makes it a good option if you have a perforated eardrum, narrow canals, or a history of ear infections. The infection risk is very low, and it handles both soft and hard wax with precision. Many ear specialists consider it the safest available method.
Irrigation
Warm water is gently flushed into the canal to dislodge softened wax. It tends to work best on soft wax and is a familiar, widely available option in primary care offices. However, it isn’t appropriate for people with a ruptured eardrum, chronic infections, or a history of ear sensitivity. Because it relies on water pressure rather than direct visual guidance, it carries a slightly higher chance of causing temporary dizziness or introducing moisture that could lead to infection.
Providers often ask you to use softening drops for a few days before a scheduled irrigation or microsuction appointment. Pre-softened wax comes out faster and more comfortably.
Avoid Ear Candling
Ear candling involves placing a hollow, cone-shaped candle into the ear canal and lighting the far end, supposedly creating suction that draws wax out. It doesn’t work. Measurements taken during controlled studies show that the technique produces no negative pressure inside the canal. Worse, it’s genuinely dangerous. Burns to the ears and scalp are the most commonly reported injuries. Melted candle wax can drip into the canal and make the blockage worse. There are documented cases of ruptured eardrums and even house fires. No major medical organization endorses the practice.
Preventing Recurring Buildup
If you’ve dealt with impacted wax once, you’re likely to deal with it again. The anatomy and wax production patterns that caused the first episode don’t change. A few strategies can reduce how often it happens.
Stop inserting anything into your ear canal. This includes cotton swabs, which should only be used on the outer ear. If you wear hearing aids, clean them daily and have your ears checked for wax buildup at each audiology appointment. For people prone to recurring impaction, periodic use of softening drops (mineral oil, olive oil, or saline) once or twice a week can keep wax loose enough for the ear’s self-cleaning mechanism to handle. Your provider can show you how to do this safely.
If buildup keeps returning despite home care, scheduling professional cleanings once or twice a year is a practical, low-effort way to stay ahead of it. This is especially worthwhile for older adults and anyone who relies on hearing aids, where undetected wax buildup can be mistaken for device malfunction or age-related hearing decline.
