Can earwax cause hearing loss?

Earwax is normal and healthy, protecting and cleaning the ear canal. Problems arise only when it builds up enough to block the canal, which can dull or muffle your hearing. The good news is that wax-related hearing loss is generally temporary and often resolves once the blockage is safely cleared, unlike permanent inner-ear hearing loss. So while wax can absolutely reduce your hearing, it is usually one of the more straightforward causes to address.

How does earwax affect hearing?

When wax accumulates and forms a plug, it physically stops some sound reaching the eardrum. This is a form of conductive hearing change. Alongside reduced hearing, a wax blockage can cause:

• A feeling of fullness or blockage in the ear.
• Muffled or dulled sounds.
• Earache or mild discomfort.
• Ringing in the ear (tinnitus).
• Occasionally, a sense of imbalance.

Because these symptoms can overlap with other causes of hearing loss, it is not always obvious that wax is to blame without someone examining the ear canal.

Who is more prone to wax build-up?

Some people simply produce more wax than others, and a few factors make a blockage more likely. You may notice it more often if you:

• Wear hearing aids, earbuds or earplugs regularly, which can slow the wax's natural exit.
• Have narrow or particularly hairy ear canals that trap wax.
• Use cotton buds, which tend to push wax further in.
• Are older, as wax can become drier and harder with age.

Recognising that you are prone to build-up can help you plan occasional checks rather than waiting until your hearing is noticeably dulled.

Why do cotton buds make it worse?

It is very common to reach for a cotton bud, but this often pushes wax deeper and packs it against the eardrum, making a blockage worse and occasionally causing damage. The ear is usually self-cleaning, so poking objects into the canal tends to interfere with that natural process. Avoid cotton buds, hairpins and ear candles, which are not recommended and can be harmful. For most people, the outer ear only needs a gentle wipe with a cloth, and nothing should be inserted into the canal itself.

How is a wax blockage removed?

Safe wax management is best done by a professional who can see inside your ear. Depending on the situation, softening drops, gentle irrigation or microsuction may be appropriate. An audiologist or GP can examine the canal, decide the safest method for you, and check your hearing afterwards to confirm it has improved. Trying to dig it out yourself risks pushing it further in or scratching the delicate canal, so professional removal is both safer and usually more effective.

What if my hearing does not improve?

If clearing the wax restores your hearing, the problem was simply the blockage. If muffled hearing remains once the canal is clear, there may be another cause, such as a sensorineural change, that a hearing test can identify. At Hearing Help in Newport Marketplace on the Redcliffe Peninsula, our audiologists can examine your ears, discuss safe wax-removal options, and assess your hearing if needed, all explained in plain language. Booking a hearing assessment needs no referral. If wax has been dulling your hearing, addressing it is often a simple and satisfying way to hear clearly again.
