Earwax has a bit of an image problem. Most of us think of it as something unpleasant to be scrubbed away, when in reality it is a clever, hard-working substance that keeps our ears healthy. The trouble starts only when there is too much of it, or when it ends up in the wrong place. Understanding why wax builds up, how to spot the signs, and when it is time to seek help can save you a great deal of discomfort and protect your hearing.
This guide from Ear Rescue in Boston, Lincolnshire, walks you through everything you need to know about earwax build-up, in plain English and without the scare stories.
What earwax actually does
Earwax, properly known as cerumen, is produced by specialised glands in the outer third of your ear canal. It is a mixture of these secretions, dead skin cells and the natural oils of the ear. Far from being a nuisance, it serves several genuinely useful purposes.
It acts as a protective barrier, trapping dust, dirt and tiny foreign particles before they can travel deeper towards the eardrum. It keeps the thin, sensitive skin of the ear canal moisturised, preventing it from becoming dry, itchy and cracked. It even has mild antibacterial and antifungal properties, helping to ward off infection. And through the natural movements of your jaw when you talk and chew, old wax is gradually carried outwards to the opening of the ear, where it dries up and falls away unnoticed.
In other words, a healthy ear is largely self-cleaning. For most people, most of the time, wax simply is not a problem.
Why wax builds up
So if ears clean themselves, why do so many people end up blocked? There are several common reasons, and often more than one is at play.
The shape of your ear canal. Some people are simply born with narrower or more curved ear canals, which make it harder for wax to migrate out naturally. Hairy canals can have the same effect, trapping wax along the way.
The type of wax you produce. Wax varies from person to person. Some people produce drier, flakier wax, while others produce a wetter, stickier type that is more prone to clumping and compacting. Genetics play a large role here, and it is nothing to be concerned about.
Age. As we get older, wax tends to become drier and harder, and the natural outward migration slows down. This is one reason wax build-up is more common in older adults.
Cotton buds and other objects. This is the big one. Using cotton buds, hairgrips, rolled tissue or anything else to “clean” inside the ear usually does the opposite of what is intended. Instead of removing wax, it pushes the bulk of it deeper down the canal, packing it tightly against the eardrum where it cannot escape. Cotton buds are one of the most common causes of impacted wax we see.
Hearing aids and earphones. Anything worn regularly in the ear can interfere with the natural clearing process and stimulate extra wax production. Hearing aid users, musicians who use in-ear monitors, and people who wear earplugs frequently are all more prone to build-up.
Skin conditions. Conditions such as eczema or dermatitis affecting the ear canal can increase the amount of dead skin in the mix, contributing to blockages.
The signs and symptoms to watch for
Wax build-up rarely happens overnight. It tends to creep up gradually, which is why people are sometimes surprised by how blocked they have become. The most common symptoms include:
- Muffled or reduced hearing, often in one ear more than the other. This is the classic sign and the reason most people get in touch.
- A feeling of fullness or blockage, as though your ear is stuffed with cotton wool.
- Earache or mild discomfort, particularly if the wax is pressing on the eardrum or canal wall.
- Tinnitus, meaning ringing, buzzing or humming sounds in the ear that have no external source.
- Itching inside the ear.
- Dizziness or a feeling of imbalance in some cases, because the ear plays an important role in balance.
- A blocked sensation that comes and goes, sometimes worse after showering or swimming when water makes the wax swell.
It is worth noting that these symptoms can also have other causes. Muffled hearing and tinnitus, for example, are not always down to wax. That is exactly why a professional assessment is so valuable: it tells you whether wax really is the culprit.
When you should seek help
For mild, occasional build-up, a few drops of olive oil over a few days can sometimes encourage wax to clear on its own. But there are clear situations in which you should stop trying home remedies and see a professional.
You should seek help if your hearing has noticeably reduced, if you have a persistent blocked feeling that will not shift, if you are experiencing earache, or if tinnitus or dizziness has appeared alongside the blockage. You should also seek help if home softening drops have not worked after a week or so, or if build-up keeps returning.
Some symptoms warrant prompt medical attention rather than routine wax removal. If you have sudden hearing loss, severe pain, discharge or bleeding from the ear, a high temperature, or symptoms following an injury, these need to be assessed by a doctor, because they may point to something other than wax. A responsible ear care practitioner will always check for these red flags and refer you on if needed.
Why you should not try to dig it out
It is tempting, when an ear feels blocked, to reach for a cotton bud or something similar. Please resist. The ear canal is delicate and the eardrum is fragile. Inserting objects risks scratching the skin, introducing infection, pushing wax deeper, or in the worst cases perforating the eardrum. The old saying that you should never put anything smaller than your elbow in your ear is good advice.
Ear candling, which some people try, is another method best avoided. There is no good evidence that it removes wax, and it carries a real risk of burns and dripping wax. Professional removal is safer, faster and far more effective.
How professional removal works
When you come in for wax removal, the first step is always an assessment. Using an otoscope, your practitioner looks inside the ear to see how much wax there is, where it is sitting, and whether the canal and eardrum look healthy. They will ask about your history, including any past ear surgery, perforations or infections.
Depending on what they find, they will recommend either microsuction, a dry method using gentle suction under magnified vision, or irrigation, a warm-water flush for softened wax. Both are safe and comfortable, and the whole process is usually over within half an hour. Most people walk out hearing noticeably better straight away.
Preventing build-up in the future
If you are prone to wax problems, a little routine maintenance goes a long way. Putting a few drops of olive oil into your ears once a week keeps the wax soft and mobile so it can clear naturally. Avoid cotton buds completely. Dry your ears gently after swimming or bathing, tilting your head to let water drain out. And if you wear hearing aids or earphones a lot, keep them clean and give your ears regular breaks where practical.
For those whose ears simply make a lot of wax, the kindest approach is a regular check-up, perhaps every six to twelve months, so that wax is cleared before it becomes a problem rather than after.
Frequently asked questions
Is earwax a sign of poor hygiene? Not at all. Wax is normal and healthy. How much you produce is largely down to genetics and the shape of your ears.
Can wax build-up damage my hearing permanently? Wax itself causes temporary, reversible hearing loss. Once it is removed, hearing returns. However, ignoring symptoms for a long time is not wise, because other causes of hearing loss can hide behind a simple blockage.
How do I know if it is wax or something else? You often cannot tell on your own, and that is fine. A quick professional look inside your ear gives you a clear answer.
Can children have wax removed? Children can be more sensitive and their ears are smaller, so removal should always be carried out carefully by a trained professional after assessment.
In summary
Earwax is a natural, useful part of a healthy ear, and most of the time it looks after itself. Build-up happens for all sorts of ordinary reasons, from the shape of your canal to the well-meaning use of cotton buds, and it shows up as muffled hearing, fullness, earache, tinnitus or itching. The safest response is not to dig at it, but to have your ears assessed and, if needed, cleared by a professional.
If any of this sounds familiar, you do not have to live with blocked, uncomfortable ears.
