What Earwax Actually Does
Cerumen, the clinical name for earwax, gets treated like something to scrub out on sight. In reality it's a substance your ear canal manufactures deliberately, and it's doing real work. The outer third of the ear canal contains ceruminous and sebaceous glands that combine oily secretions with shed skin cells to form cerumen, and that mixture moisturizes the canal skin while creating a barrier against water, dust, and insects trying to get further in. [1]
Cerumen is also mildly acidic and has documented antibacterial and antifungal properties, which helps keep the ear canal an inhospitable environment for the kind of microbial overgrowth that leads to outer ear infections. [2] Under normal circumstances, the ear canal clears itself: jaw movement from talking and chewing gradually migrates old cerumen outward, where it dries and flakes away on its own. The problem isn't earwax existing, it's this self-clearing process failing to keep up.
When Buildup Becomes Impaction
Cerumen impaction is the clinical term for buildup that's accumulated enough to cause symptoms or to block a clinician's view of the eardrum. It's more common than most people assume, affecting up to roughly 6% of the general population, and considerably more in specific groups. [1]
The recognized symptoms of impaction include a sensation of fullness or blockage, muffled or reduced hearing, itching, and in some cases pain, tinnitus, or dizziness. [1] None of these are dangerous on their own, but they're also not something to just live with indefinitely, especially if hearing loss or dizziness shows up alongside them, since those symptoms can overlap with other conditions that deserve a proper look.
Who's More Prone to Impaction
- Hearing aid and earbud users. Anything sitting in the ear canal regularly can interfere with cerumen's normal outward migration and, in some cases, stimulate more wax production, which is why impaction is disproportionately common in this group. [1]
- Older adults. Aging reduces the number and activity of ceruminous glands, producing a drier, less mobile type of wax, often paired with coarser ear canal hair in men, and impaction rates climb accordingly. Estimates put impaction at around 30% or more in elderly adults generally, and as high as 57% in nursing home residents. [1] This is one of several reasons hearing changes get more common with age; see our guide to age-related hearing loss for the broader picture.
- People with narrow, curved, or irregularly shaped ear canals. Bony growths (exostoses) or an unusually shaped canal can physically slow the outward migration cerumen relies on.
- Anyone who regularly inserts objects into the ear canal. Cotton swabs, bobby pins, and similar habits don't just risk injury, they routinely push wax deeper and pack it against the eardrum instead of removing it. [1]
Why Cotton Swabs and Candling Are Discouraged
The advice to avoid cotton swabs isn't overcautious folklore. Because most cerumen sits in the outer third of the canal, a swab typically shoves it further inward toward the eardrum rather than lifting it out, and the same motion carries a real risk of scratching the canal skin or, less commonly, perforating the eardrum itself. [1] Clinical guidance from the American Academy of Otolaryngology–Head and Neck Surgery's updated cerumen impaction guideline specifically advises against inserting cotton swabs or similar objects into the canal as a matter of routine ear care. [3]
Ear candling, the practice of placing a lit hollow candle in the ear canal to supposedly draw wax out by suction, fares even worse under scrutiny. Studies measuring what actually happens found the candles don't generate meaningful negative pressure, don't remove wax, and carry documented risks of hot wax dripping into the canal, burns, and candle debris itself becoming lodged in the ear. [4] It's for these reasons, and the complete absence of evidence it works, that ear candling is specifically flagged as a contraindicated intervention in current clinical guidance. [3]
What Actually Works
For mild to moderate buildup that isn't causing significant symptoms, cerumenolytic (wax-softening) ear drops are a reasonable first step. A Cochrane review of the evidence found that active drops used for several days modestly outperformed no treatment, though the certainty of that evidence is rated low, and no single commercial formula, whether oil-based or water-based, proved reliably better than the others or than plain saline. [5] Reassuringly, the same review found reported side effects were mild (irritation or an unpleasant smell) and no serious adverse events. [5]
Softening the wax is often only half the job, since it still needs to come out. Ear irrigation, gently flushing the canal with warm water or saline, is a standard, well-established next step and is frequently paired with softening drops used beforehand. [6] For impaction that doesn't respond to home measures, or in people with a history of eardrum perforation, ear surgery, or diabetes, manual removal by a clinician using specialized instruments or suction under direct visualization is the recommended route rather than home irrigation. [3]
When to See a Doctor
See a clinician if fullness, muffled hearing, or itching doesn't resolve with over-the-counter softening drops, if you have ear pain, drainage, or a known eardrum perforation, or if hearing loss, dizziness, or tinnitus appears suddenly or on one side only. Anyone with diabetes, a compromised immune system, or a history of ear surgery should have wax removed by a professional rather than attempting home irrigation, since the risk of infection or injury is meaningfully higher in those situations.
Once Your Ears Are Clear, Keep Your Routine Going
Safe earwax care keeps the canal clear, and a daily wellness habit keeps your hearing routine on track, once any persistent muffled hearing has been checked by a clinician. Audifort is a morning liquid designed to support healthy hearing, and it takes only seconds each day. The 90-day money-back guarantee makes it a risk-free way to try.
Frequently Asked Questions
Is it normal to have earwax, or should ears be completely clean?
Some cerumen is normal and healthy, it's a sign the ear canal's protective system is working. The goal isn't a completely wax-free canal, it's preventing buildup from accumulating enough to cause symptoms or block the eardrum from view.
Why do cotton swabs make earwax problems worse instead of better?
Most earwax sits in the outer part of the ear canal, where it would naturally migrate out on its own. A cotton swab tends to push a portion of that wax deeper toward the eardrum, compacting it rather than removing it, which is how casual cleaning habits end up causing the very impaction people are trying to prevent.
Are over-the-counter earwax removal drops safe to use at home?
For most people without a perforated eardrum, ear tubes, or active ear infection, cerumenolytic drops used as directed are considered low-risk, with mild irritation being the most commonly reported side effect. They work best for softening mild buildup; more significant impaction may still need irrigation or professional removal afterward.
Does wearing hearing aids or earbuds all day cause earwax buildup?
It can contribute to it. Anything that regularly sits in the ear canal can interfere with cerumen's normal outward movement, which is one reason regular hearing aid and earbud users are advised to have their ears checked periodically rather than waiting for symptoms to show up.
