Why Should You Avoid Cotton Buds?

Most people use a cotton bud after a shower without thinking, believing it helps. But what happens inside your ear is different from what you expect.

As a pharmacist, I often see the effects of cotton bud use: impacted wax, irritated canals, and perforated eardrums. These are common, not rare, results of a habit few were warned against.

Quick Answer:

• You should avoid cotton buds because ears clean themselves naturally. 
• Inserting anything into the ear canal pushes wax deeper, raises infection risk, and can cause lasting damage to the eardrum. 
• Safe alternatives exist and work far better.

What Are Cotton Buds Actually Designed For?

Cotton buds were never designed to go inside the ear canal. The original patent, filed in the 1920s, described them for use around the outer ear, nostrils, and for applying ointments to the skin.

Somewhere along the way, the habit of inserting them into the ear became normalised. Packaging on many brands still carries a warning against internal use, but most people never read it.

You can clean the outer part of your ear. But it’s not recommended for cleaning the canal.

Why You Should Avoid Cotton Buds: Key Risks

Pushing Earwax Deeper into the Ear Canal

Earwax, known clinically as cerumen, moves outward on its own. The skin inside your ear canal grows in a slow outward spiral, carrying wax and debris with it. It’s the body’s self-cleaning mechanism.

When you insert a cotton bud, you compress the wax. The bud acts like a plunger, pushing cerumen toward the eardrum rather than out of the canal. Over time, this leads to a blockage that your ear cannot shift on its own.

Impacted wax is a common reason people present to pharmacists or GP with ear complaints. In many cases, the ear canal does not require routine cleaning.

Increased Risk of Ear Infections

The ear canal has a slightly acidic pH. It keeps bacteria and fungi from growing. Cerumen contributes to this environment and contains antimicrobial compounds.

When you regularly remove this wax with cotton buds, you strip away the ear’s natural defences. The canal becomes drier, more alkaline, and more vulnerable to infection. Swimmer’s ear, or otitis externa, is the most common result. It causes pain, itching, discharge, and sometimes temporary hearing loss.

Cotton buds can also introduce bacteria directly into the canal, particularly if they are used after being left on a bathroom surface.

Damage to the Eardrum

The eardrum sits at the end of the ear canal, roughly two to three centimetres in. That sounds like a safe distance. But it’s not, especially if you push harder to dislodge wax that a bud has already compacted.

Eardrum perforations from cotton bud use happen a lot. They are more likely if the bud is inserted when someone is startled, if a child is being cleaned by an adult who misjudges depth, or if there is already inflammation making the tissue fragile.

A perforated eardrum is painful and usually heals on its own, but recovery takes weeks. In some cases, it does not heal fully without intervention.

Hearing Problems Due to Wax Impaction

Compacted earwax can cause a noticeable drop in hearing, a sensation of fullness, tinnitus, and dizziness. These symptoms are often mistaken for something more serious.

The frustrating part is that many people respond to these symptoms by using more cotton buds, which makes blockage worse. Impacted wax is one of the most treatable causes of hearing loss. But only if it is addressed properly.

Common Myths About Ear Cleaning

“Clean ears are healthy ears.” 

That’s not true. A small amount of wax is normal and protective. Completely wax-free ears are actually more prone to dryness, irritation, and infection. 

“If I can see or feel wax, I need to clean it out.” 

Visible wax in the outer ear is fine to wipe gently with a cloth. Wax you can feel but not see is deep enough to leave alone. Your ear is already moving it outward.

“Cotton buds are safe if I’m careful.” 

Even careful use compresses wax rather than removing it. There is no technique that changes this. The problem is the direction of force, not the pressure applied.

“I’ve always done it and never had a problem.” 

Wax impaction builds gradually. Many people do not notice the cumulative effect until there is a clear blockage, an infection, or a sudden dip in hearing. No obvious problem today does not mean the practice is harmless.

Safe Alternatives to Cotton Buds

The good news is that most people do not need to clean their ear canals at all. For the majority, the ears manage perfectly well without help. If you do experience a build-up, here are options that actually work.

Olive oil drops

A few drops of warmed olive oil, applied two to three times a week for a fortnight, softens compacted wax so the ear can expel it naturally. This is commonly recommended in NHS guidance as a first-line option for softening earwax.

Sodium bicarbonate ear drops

Available over the counter from most pharmacies. These help dissolve wax and are suitable for regular maintenance if you are prone to build-up.

Ear irrigation or microsuction

If olive oil has not resolved the blockage after two weeks, a pharmacist or GP can arrange ear irrigation or microsuction. These are the only methods that safely remove wax from the canal during professional earwax removal. Microsuction in particular is precise, and does not require any prior softening.

A warm flannel

For the outer ear only, a warm damp cloth after a shower is enough to keep things clean. It’s effective for most people. 

Signs You Have Damaged Your Ears

Some people only realise cotton buds have caused a problem once symptoms appear. Here are some signs which may indicate damage:

• Ear pain that persists or worsens, particularly if you recently used a cotton bud or have had a recent cold.
• Tinnitus, a ringing, buzzing, or hissing in one or both ears, especially if it is new or getting louder.
• Sudden or gradual hearing loss in one ear that was not there before.
• Dizziness or balance problems can signal pressure changes or more serious damage near the eardrum.
• A feeling of blockage or fullness that does not resolve on its own after a few days.

Note: Any of these symptoms, particularly hearing loss or dizziness, warrants prompt assessment. Do not reach for a cotton bud if you notice them.

When to See an Earwax Removal Specialist

If the issue is wax-related, a pharmacist-led earwax removal service is often the faster and more appropriate option. You should seek professional earwax removal if:

• Olive oil drops have not cleared a blockage after two weeks
• You have a history of ear infections, a perforated eardrum, or ear surgery
• Hearing loss or tinnitus has come on recently and feels linked to the ear
• A child under 12 has symptoms of wax blockage
• You are experiencing pain or discharge alongside the blockage

Microsuction is widely available through community pharmacies across the UK and does not usually require a GP referral. It is safe, effective, and takes around 15 to 20 minutes.

FAQs

Can cotton buds cause permanent hearing loss? 

Permanent hearing loss from a single use is unlikely in healthy ears. However, repeated use over time may cause impactions, infections, and eardrum scarring, risking long-term hearing damage. Early detection usually allows for reversal.

Is it safe to use cotton buds on children? 

No. Children’s ear canals are narrower and more delicate, increasing the risk of injury and wax impaction. Use a warm flannel on the outer ear instead. For wax build-up or hearing issues, consult a pharmacist or GP.

Why do some people produce more earwax? 

Wax production varies genetically. Narrow or hairy ear canals and frequent use of hearing aids or earbuds can cause more buildup by blocking wax migration. More wax doesn’t mean the ears are dirty.

Can I use ear candles instead of cotton buds? 

No. Ear candling lacks clinical support and risks burns, blockages, and perforations. UK medical bodies do not recommend it. Olive oil drops and professional microsuction are safer alternatives.

How do I know if my earwax is impacted? 

Impacted wax causes fullness, muffled sounds, tinnitus, and sometimes dizziness. Symptoms develop gradually and can affect one ear. A pharmacist can check with an otoscope to confirm if wax is the cause.

Conclusion

Cotton buds are commonly used but are not recommended for the ear canal. They can increase the risk of wax impaction, infection, and eardrum injury. Ears clean themselves, so it’s best to leave them alone.

For build-up, try olive oil drops first. If that fails, professional earwax removal is safe, quick, and affordable.
