Earwax, medically termed cerumen, is not a sign of poor hygiene. It is produced by glands in the outer third of the ear canal to trap dust and repel water, and in most people, it clears on its own through ordinary jaw movement while chewing and speaking. Problems only arise when wax builds up faster than it can migrate out, or when something pushes it further in rather than letting it exit naturally.
Some ears simply produce more cerumen than others, and this varies by individual rather than by how often someone cleans their ears. Wearing hearing aids, earphones, or earplugs regularly can interfere with the ear’s natural self-clearing motion, as can a naturally narrow or curved ear canal. Older adults tend to produce drier, harder wax that is more prone to impaction, and repeated use of cotton buds or similar objects is a well-documented contributor to buildup at any age.[1]
When wax accumulates enough to block the canal, it is called cerumen impaction. This can cause a blocked or full feeling in the ear, muffled hearing, mild discomfort, and occasionally tinnitus (ringing in the ear) or a slight cough reflex if the wax presses on a nerve near the canal wall.
Cotton buds are a leading cause of the very problem people use them to solve. The ear canal narrows and curves, and pushing a cotton bud in does not remove wax so much as compact it against the eardrum, driving it deeper with each attempt. The cotton tip can also detach and lodge in the canal, and repeated insertion can scratch the delicate skin lining, raising the risk of infection or, in more forceful cases, a perforated eardrum.[1]
A 20-year review of US emergency department records found that ear cleaning was the most frequently documented reason behind these injuries, and the child was usually handling the cotton bud alone rather than a parent doing it for them.[4]
Ear candling, sometimes marketed as a natural detox method, carries its own risks without the removal benefit it claims. There is no reliable evidence that the vacuum effect it describes actually draws wax out, and the open flame near the head creates a real risk of burns to the face, scalp, or ear canal, along with candle wax dripping into the ear itself.
Controlled testing has found that ear candles create no negative pressure and draw no wax from the canal, and a survey of ear, nose, and throat specialists linked the practice to burns and other injuries requiring treatment.[3]
The same caution applies to any narrow object, whether a hairpin, a rolled tissue corner, or a fingernail. None of these is designed to navigate the ear canal safely, and all of them raise the same risks of impaction or injury.
For mild buildup without pain, discharge, or hearing loss, softening the wax is a reasonable first step before it needs clinical removal. Over-the-counter cerumenolytic drops, or simple options like olive oil, loosen the wax so it migrates out on its own rather than dissolving it instantly. A typical regimen is 2 to 3 drops in the affected ear, lying on your side for 5 to 10 minutes, repeated 3 to 4 times a day for 3 to 5 days. Wax often clears within about 2 weeks on this schedule.[2] Softening drops are not suitable for a known or suspected perforated eardrum, ear pain, or discharge. These need a specialist’s assessment first, not home treatment. This will not clear significant impaction, but it often resolves mild blockage on its own.
Bulb syringe kits sold for home ear irrigation exist. They carry real risk without professional guidance. Incorrect water pressure or temperature can cause dizziness, and undiagnosed eardrum damage makes irrigation unsafe. If softening drops alone do not relieve the blocked feeling within a few days, that is the point to move to a clinic rather than trying a stronger home method.
At an ENT clinic, earwax is removed under direct visualisation, meaning the specialist can see exactly what they are doing throughout the procedure rather than working blind. Three methods are common. The choice between them depends on the wax’s consistency, the shape of the ear canal, and any prior ear conditions.[1][2]
Microsuction uses a fine suction device under a microscope or headlight to draw the wax out directly. It does not introduce water into the ear canal, which is why it is often the method chosen for patients with a history of ear infections or a perforated eardrum, where irrigation is not suitable.
Ear irrigation flushes the canal with warm water at a controlled pressure and temperature, using a purpose-built device rather than a bulb syringe. It works well for softer wax and is often used after a course of softening drops.
Curettage uses a small, curved instrument to gently scoop wax out under direct vision. It suits wax sitting closer to the canal opening and is often used alongside the other two methods rather than as a standalone approach.
Microsuction and curettage are performed under direct vision, so the clinician can stop before an instrument reaches the eardrum or immediately if the patient reports discomfort. Irrigation is preceded by an otoscopic check to confirm the eardrum is intact and there is no infection, since the flush itself is not directly visualised in the same way. That is the core safety difference from any home method: a clinician has assessed the canal and eardrum before treatment begins, not after something has already gone wrong.
Mild fullness that softening drops relieve within a few days rarely needs a clinic visit. A visit becomes appropriate when symptoms persist or when certain signs appear, since they can indicate something beyond ordinary wax buildup.
Any of these warrants an examination with an otoscope, which lets a specialist see the full canal and eardrum before deciding on the safest removal method. This is also the point where an ENT specialist can rule out other causes of the same symptoms, since blocked hearing, dizziness, and ringing can stem from conditions well beyond earwax.
A consultation starts with an otoscopic examination to confirm that wax is causing the symptoms and to check the eardrum’s condition beforehand. Depending on what the specialist sees, they may prescribe softening drops for a few days before the appointment to make removal more comfortable, then proceed with microsuction, irrigation, or curettage as appropriate on the day. How much relief follows removal depends on how much the impaction was contributing to the original symptoms, which the specialist can assess once the wax is cleared.
Recurrent wax buildup is common in people who wear hearing aids or earplugs regularly, and a specialist can advise on a reasonable check-up interval based on how quickly wax tends to reaccumulate for that individual, rather than a fixed schedule that applies to everyone.
To find out whether your symptoms point to earwax buildup or something else, speak with an ENT specialist at Novena ENT for an assessment.
