Ear Wax Explained: What Is Normal, What Is Not, And How To Deal With It Safely

It often starts in the shower. One ear goes dull, as though someone has turned the volume down on that side, and your hand is already reaching for a cotton bud. If that sounds familiar, you are in good company. Ear wax is not dirt, and it says nothing about how clean you are. Most of the trouble people have with it begins with a well-meant attempt to get rid of it.

What Ear Wax Is Actually For

Ear wax, or cerumen, is made by glands in the outer part of the ear canal. It keeps the thin skin of the canal supple, catches dust before it can travel deeper, and helps to slow the growth of bacteria.

Your ears also clean themselves. The skin of the canal grows slowly outward from the eardrum and carries old wax along with it. Every time you talk or chew, the movement of your jaw nudges that wax a little further. At the opening, it dries, flakes, and falls away, usually without you noticing. A canal with no wax at all can become dry and itchy, so a spotless ear is not the goal.

What Normal Looks Like

Much of the worry about wax is really worry about how it looks. Wax can be yellow or brown, soft and sticky, or grey, dry and flaky. Healthify, the New Zealand health information service, explains that the colour and texture of ear wax vary from person to person, and that the drier, flakier kind is common in people of Asian and Pacific heritage. None of these is a sign that anything is wrong.

What does deserve attention is anything that behaves like a discharge: fluid that runs from the ear, smells unpleasant, or has blood in it. Severe pain is not something to put down to wax either. Both are covered further down.

Why Some Ears Block, And Others Never Do

For most people, this system runs quietly for a lifetime. For others, wax builds up faster than it can leave. The usual reasons are:

• ear canals that are naturally narrow or hairy
• wax that is naturally hard or dry
• getting older, because the skin of the canal becomes drier
• hearing aids, earplugs and earbuds, which sit in the canal and get in the way of wax on its way out
• skin conditions around the ear or scalp, or regular work in dusty places
• Pushing things into the ear, which interrupts the self-cleaning process and sends wax back down the canal

If you wear hearing aids and feel you are forever dealing with blocked ears, you are not imagining it. It comes with the territory, and it is manageable.

How To Tell When Wax Is The Problem

Wax needs treating in only two situations: when it causes symptoms, or when it stops a clinician from seeing the eardrum. That is how the American clinical practice guideline on earwax defines a blockage worth treating. Wax that is sitting there and bothering no one should be left alone.

The symptoms to watch for are:

• a blocked or full feeling in the ear
• muffled hearing
• itching
• ringing or buzzing (tinnitus)
• occasionally, dizziness or a dull ache
• For hearing aid wearers, whistling or a drop in performance

The difficulty is that every item on that list can have another cause. Mayo Clinic makes the point that symptoms alone cannot tell you whether wax is to blame, because someone has to look inside the ear. A quick check by a GP, nurse or audiologist settles the question and is far safer than guessing.

Signs That Should Not Be Put Down To Wax

Some symptoms need prompt medical attention and should never wait on a bottle of ear drops:

• Hearing that drops suddenly, over hours or a few days, in one or both ears. People often assume it is wax or a cold and wait it out. In fact, sudden hearing loss should be treated as a medical emergency, because treatment works best when it starts early. See a doctor the same day if you can.
• Hearing loss in one ear together with numbness or drooping on the same side of the face. Get urgent medical help.
• Severe pain, or pain that keeps returning.
• Discharge or bleeding from the ear.

The Habits That Make Things Worse

Cotton buds cause more wax trouble than anything else. Instead of lifting wax out, they push it deeper and pack it down, and they can scratch the canal or, occasionally, injure the eardrum. Hairpins, keys and fingernails carry the same risks. Patient advice drawn from the same guideline also warns that cleaning too often can irritate the canal and may even make a blockage more likely.

Ear candles are best avoided too. Healthify is blunt about them: they do not work and can cause serious injury. The guideline tells clinicians to advise against them. The old saying still holds: nothing smaller than your elbow belongs in your ear.

If you have used cotton buds for years, there is no need to feel guilty. Most of us were taught to. It is just a habit worth dropping.

What You Can Safely Try At Home

The outside of the ear can be wiped with a damp cloth as part of ordinary washing. That is all the cleaning a healthy ear needs.

For a mild blockage, softening drops are a reasonable first step. You can buy them from a pharmacy or use a plain oil. The NHS routine for earwax build-up is a useful model. Lie on your side with the affected ear facing up, put in two or three drops, and stay there for five to ten minutes so they can soak in. Repeat three or four times a day for three to five days. Softened wax can then take up to two weeks to work its way out.

Two practical points. Let the drops reach room temperature first, because cold liquid in the ear can make you dizzy. And ask your pharmacist which product or oil suits you, since recommendations differ a little between health services, and almond oil is not suitable for anyone with an almond allergy.

It also helps to have realistic expectations. A Cochrane review of ear drop trials found that five days of drops raised the share of ears that cleared completely from about one in twenty to about one in five. It found no good evidence that one type of drop works better than another, and it rated the overall evidence as low quality. So drops are worth trying; they will not always be enough, and that is no failing of yours.

Drops are not for everyone. Do not use them, and speak to a pharmacist or doctor instead, if you have or might have a hole in your eardrum, if you have had ear surgery, if you have an ear infection now, or if you have had a middle ear infection in the past six weeks.

Home irrigation kits are sold in pharmacies, but Healthify describes flushing your own ears as less safe than having it done by a clinician, because irrigation can damage the ear if it is not done carefully.

If your ear has not cleared after about five days, or it is so blocked that you cannot hear on that side, have it looked at.

What Happens At A Professional Removal

In New Zealand, wax removal is offered by audiology clinics, ear nurse clinics and some general practices, often without a referral.

Clinics that offer ear wax removal in Auckland most often use microsuction. The clinician looks into your ear under magnification and a bright light, then lifts the wax away with a fine suction tube. Because the canal is in view the whole time, the work is precise, and no water goes into the ear. It is noisy, but it should not hurt, and Healthify describes it as the safest of the removal procedures.

Some clinicians also use small hand instruments, such as a fine loop or scoop, or irrigation with warm water. If irrigation is suggested, it should be done with a purpose-made electronic irrigator. NICE guidance on earwax removal advises against the older method of manual syringing for adults.

A few things help the appointment go smoothly:

• Mention any history of a perforated eardrum, grommets, ear surgery, or ear infections, and say if you have diabetes or a weakened immune system. These affect which method is suitable.
• Ask when you book whether to soften the wax beforehand, and with what. Some clinics prefer a plain oil to certain pharmacy drops.
• Expect a short visit. Many people notice the difference at once, although very hard, impacted wax sometimes needs more softening and a second appointment. That is normal and does not mean anything has gone wrong.

How Often Is Often Enough

There is no standard schedule, and many people never need professional removal at all. If your ears give you no trouble, there is nothing to book.

For people whose ears block repeatedly, a routine makes sense. The specialist body behind the American guideline suggests that anyone prone to repeat blockages, or who wears hearing aids, should consider a check and preventive clean every six to twelve months. People who book regular ear cleaning in Auckland are usually hearing aid wearers, or people with narrow canals who have learned how quickly their ears fill. Your clinician can suggest an interval based on what they see. Healthify also notes that older adults, hearing aid wearers and people who naturally make a lot of wax can ask about using softening drops once a week as prevention.

When Clear Ears Still Sound Dull

Wax is only one cause of muffled hearing. Fluid behind the eardrum, infection, and gradual hearing loss can all feel much the same from the inside. If your ears have been cleared and things still sound dull, or a clinician looks in and finds no wax at all, ask about a hearing test. An audiologist can check the health of the ear canal and eardrum and measure how well you are hearing, which gives you something concrete to act on.

Looking After Your Ears Day To Day

Healthy ears ask very little of you. Leave the canal alone, wipe only what you can see, keep hearing aids and earbuds clean, and have someone look when symptoms appear. Chewing helps wax along, and Healthify notes that some people find sugar-free gum useful for that reason. Beyond that, ears mostly look after themselves, and the best thing you can do is let them.
