Why Cotton Buds Are Bad for Your Ears
Cotton buds are one of the most commonly used — and most consistently harmful — ear care products. Here's what they actually do, why the NHS advises against them, and what to do instead.
The Problem with Cotton Buds
Cotton buds feel like they're cleaning your ears. They pick up visible wax from the outer canal, they come out looking dirty, and your ear feels briefly cleaner afterwards. The problem is that what you're removing is the wax that was already on its way out — while the cotton bud pushes the deeper wax further in.
The ear canal is roughly 2.5 cm long. The eardrum sits at the end of it. A standard cotton bud is long enough to reach the eardrum — and the ear canal narrows as it goes deeper, which means wax that's pushed inward has nowhere to go. It compacts against the eardrum, forming a plug that the ear's self-cleaning mechanism can't shift.
The NHS, NICE, and the British Society of Audiology all advise against inserting anything into the ear canal, including cotton buds. The packaging on most cotton bud products now carries a warning against ear use — though this is easy to overlook. The advice is consistent across every major clinical guideline: the ear canal doesn't need cleaning, and inserting instruments into it causes more harm than good.
The Specific Risks
Wax impaction is the most common consequence of cotton bud use, but it's not the most serious. The ear canal skin is thin and sensitive, and the eardrum is closer to the entrance than most people realise. A sudden movement — a knock, a sneeze, a child bumping your arm — while a cotton bud is in the ear can cause a laceration of the canal skin or a perforation of the eardrum.
Eardrum perforation from cotton bud use is not rare. A study published in the British Medical Journal found that cotton buds are among the most common causes of ear canal foreign body injuries presenting to emergency departments. Perforation causes sudden, severe ear pain, hearing loss, and sometimes bleeding. Most perforations heal on their own over several weeks, but some require surgical repair.
Scratches to the ear canal skin from cotton buds create entry points for bacteria. The warm, moist environment of the ear canal is ideal for bacterial growth, and a minor scratch can develop into otitis externa — an infection of the outer ear canal — within days. People who use cotton buds regularly and then swim are at particularly high risk.
Cotton fibres can also detach from the bud and remain in the ear canal, acting as a foreign body that causes irritation and, occasionally, infection. This is more common with lower-quality cotton buds but can happen with any brand.
Why People Keep Using Them
Honestly, it's because they feel good. The ear canal is sensitive, and the gentle pressure of a cotton bud stimulates nerve endings in a way that many people find satisfying. There's also a psychological element — seeing wax on the cotton bud provides visible evidence of cleaning, even though the cleaning is counterproductive.
The habit is often passed down through families. If your parents cleaned their ears with cotton buds, you probably do too — and the absence of obvious immediate harm reinforces the behaviour. The damage accumulates gradually, which makes the connection between cotton bud use and wax impaction easy to miss.
Understanding that the ear cleans itself — and that earwax is protective rather than dirty — is the key to breaking the habit. The ear doesn't need to be cleaned. It needs to be left alone.
What to Do Instead
For routine ear hygiene, the outer ear — the part you can see and reach with a finger — can be wiped gently with a damp cloth or flannel during bathing. That's genuinely all that's needed for most people.
If you're prone to wax buildup, regular use of olive oil drops — two to three times weekly — keeps wax soft and easier to migrate naturally. This is the NHS's recommended approach for preventing impaction in people who are susceptible.
If you're experiencing symptoms of wax impaction — muffled hearing, fullness, tinnitus — professional removal is the appropriate response. Microsuction and ear irrigation are both safe, effective, and recommended by NICE. They work. Cotton buds don't.
Already Used Cotton Buds and Now Have Problems?
If you've been using cotton buds and are now experiencing hearing loss, ear fullness, or discomfort, there's a good chance you have compacted wax. The good news is that this is straightforward to treat professionally. Don't try to remove it yourself — the wax is likely to be hard and deeply positioned, and further attempts at self-removal will make it worse.
Start using olive oil drops for three to five days to soften the wax, then book an appointment for professional removal. If you're in significant discomfort or your hearing is severely affected, call us for a same-day assessment.
