Earwax: Should You Clean Your Ears, Are Cotton Swabs Safe, and What Is Impacted Wax?

Earwax (cerumen) is a mixture of secretions from the ceruminous and sebaceous glands of the outer ear canal, shed skin cells and fine hairs. It is produced only in the outer, cartilaginous part of the canal, near the opening, not by the eardrum. That is a useful practical clue: if wax lies right against the eardrum, it was most likely pushed there rather than made on the spot.

Earwax has protective functions. It forms a slightly acidic, lubricating layer that moisturises the skin of the canal, traps dust and small particles, makes it harder for water to get in and limits the growth of microorganisms. It is therefore not a sign of poor hygiene, and removing it completely can lead to dryness, itching and irritation of the canal skin.

The ear also has its own self-cleaning mechanism. The skin of the ear canal grows from the area of the eardrum towards the opening, like a slow conveyor belt, and jaw movements during speaking and chewing push the material outwards. Wax in the outer canal dries, crumbles and falls out or is washed away during bathing. In most people this process works without any intervention.

The amount and consistency of earwax are individual. Some people produce little and it is dry; others produce a lot and it is softer or darker. A colour from pale yellow to almost black does not by itself indicate disease. A change in quantity, a sudden odour or a purulent discharge is another matter, covered in the section on warning signs.

A swab inserted into the ear canal acts like a piston: it collects some of the wax but presses the rest into the deeper, narrower parts of the canal, where there is no longer a natural mechanism pushing it outwards. This creates a habit loop: the more often someone cleans with a swab, the more the ear 'needs' another cleaning, because the wax sits deeper. In addition, the swab irritates the skin, which responds with more secretion and shedding.

The second risk is mechanical. The eardrum lies not far from the entrance of the canal, and a sudden nudge from an elbow, a child or a pet during cleaning is enough to puncture it. A perforation may be painful and cause bleeding, tinnitus and hearing loss, and in more severe cases dizziness.

For adults we have data from a single centre: in a series from one otolaryngology clinic (Smith et al., 2012), 54 of 1,540 patients presented with a swab-induced eardrum perforation. In nearly all of those who declined surgery and were followed up, the perforation healed spontaneously (34 of 35 people, on average after about 1.75 months). Surgery was considered mainly when a perilymphatic fistula was suspected, or with facial nerve paralysis, severe vertigo or marked sensorineural hearing loss. This is single-centre data, but it illustrates two important things: that injury from a swab is real, and that most small perforations heal by themselves.

Guidelines define cerumen impaction not as the mere presence of earwax but as an accumulation that causes symptoms, prevents examination of the ear, or both. This distinction is key: wax seen in the ear of a person without complaints, whose eardrum the doctor can assess, is not a disease and needs no treatment.

Some groups develop impactions more often. The guideline lists hearing-aid users, children and people with intellectual disability or cognitive impairment who may not be able to report symptoms, and people with a narrow ear canal or bony growths (exostoses). In older people wax is often drier and harder, which favours build-up. The recommendations for clinicians explicitly include inspecting the ears of hearing-aid users at health care visits.

It is also important not to blame earwax for everything. If symptoms (hearing loss, tinnitus, dizziness) persist in whole or in part after the impaction has been cleared, the guideline recommends looking for another cause. A one-sided hearing loss that does not resolve after wax removal needs ENT assessment and audiometry.

The guideline does not name a single 'best' method. Drops, irrigation and instrumental removal are treated as equivalent options, and the choice depends on the situation, the experience of the person performing the procedure and the patient's risk factors. A 2026 review that appraised the quality of earwax guidelines for the World Health Organization's package of ear and hearing care interventions judged the AAO-HNS and the UK's NICE guidelines to be of sufficient quality. Both agree on education, diagnosis based on symptoms and examination, and the use of drops, irrigation and manual removal. They differ on manual syringes: NICE discouraged them for safety reasons, whereas AAO-HNS considered them a safe option when performed appropriately.

What about the drops themselves? A 2009 Cochrane review (Burton and Doree) included 9 trials with 679 participants and 11 different preparations. Its conclusions were cautious: trials were heterogeneous and of low to moderate quality, no clearly superior preparation could be identified, but using drops of any sort seemed better than no treatment. In some trials sterile water or saline performed comparably to wax-dissolving preparations. It is worth knowing that this review was marked as withdrawn in the database in 2018, so we treat it as an illustration of the state of knowledge at the time and not as a current source of recommendations.

Ear irrigation (syringing) is a common method, but it is not free of risk. A systematic review by German authors (Schmiemann and Kruschinski, 2009) found that controlled studies of complications from earwax removal are lacking and absolute risks could not be given. However, eardrum perforation was observed in up to about 1% of cases, and syringing seemed to cause more complications than mechanical removal with a curette. The authors noted that syringing can be delegated to trained staff only after pre-existing eardrum defects have been excluded.

The AAO-HNS guideline lists factors that change management and need to be assessed before any procedure: anticoagulant therapy, an immunocompromised state, diabetes, previous radiotherapy to the head and neck, a narrow canal, exostoses and a non-intact tympanic membrane. In these people the procedure should be performed by an experienced specialist, preferably an ENT doctor with appropriate equipment (microscope, suction).

Ear candles are advertised as a way to 'draw out' earwax by suction. The AAO-HNS guideline recommends against their use both for treating and for preventing earwax impaction. The reasoning rests on the absence of evidence of effectiveness and on documented harm: burns to the face and ear canal, wax from the candle dripping into the ear, and damage to the eardrum.

We are similarly cautious about advertisements for 'safe' cameras and curettes for self-use, which have recently become popular. Smartphone images do not replace an assessment of the eardrum by a specialist, and the risk of mechanical injury remains. We did not find controlled studies confirming that such tools are safe in the hands of lay users, so we cannot recommend them.

A hearing aid or earmould mechanically blocks the exit of the canal and hinders the natural migration of wax. That is why impactions are more common in hearing-aid users, and wax can also clog the earmould or the speaker of the aid and impair its function. The guideline recommends inspecting the ears of hearing-aid users at health care visits, and the earmould or tip of the aid is worth cleaning according to the manufacturer's instructions.

And in-ear earphones? It seems intuitive that wearing them often might favour wax build-up, but in the literature we reviewed for this article we found no reliable comparative studies confirming it. We therefore treat it as a mechanistic hypothesis, not an established fact. The practical advice is independent of this: clean earphones from the outside from time to time, do not share them, and take breaks if you feel your ear is blocked.

We write about age-related hearing loss and tinnitus in separate articles: earwax is one of the most easily reversible causes of worse hearing, so it is worth ruling it out at the start of the work-up before looking for deeper causes.

Earwax itself is rarely an urgent problem, but the symptoms that mimic it can be important. The following situations should prompt a visit to a doctor (an ENT specialist, or an urgent service in acute cases).

The best thing most people can do for their ears is to leave them alone. Earwax is part of the defence system, and repeated attempts to remove it more often create a problem than solve one. When a genuine impaction with symptoms appears, there are a few proven routes: drops, irrigation and instrumental removal, and the choice of method is best left to someone who can look at the eardrum.
