Hearing Aids and Earwax: Why Build-Up Happens Faster and What to Do About It

If you wear a hearing aid, you’ve probably noticed that earwax seems to become more of an issue than it used to be. This isn’t in your head - hearing aids genuinely change how wax behaves in the ear canal, and left unmanaged, it can quietly undermine the performance of a device you rely on every day.

Why Hearing Aids Speed Up Wax Build-Up

Earwax is normally self-clearing: chewing, talking and jaw movement gradually work it out of the canal. Hearing aids interfere with that process in a few specific ways:

• Blocked natural migration - an in-ear device sits in the same space wax needs to travel through, effectively damming it up
• Increased wax production - the ear can respond to the presence of a foreign object by producing more wax, not less
• Reduced airflow - a sealed or near-sealed canal is warmer and more humid, which softens wax and encourages it to accumulate rather than clear
• Physical compaction - repeatedly inserting and removing a mould or dome can pack wax further into the canal instead of dislodging it

The Knock-On Effect on Your Hearing Aid

Wax build-up doesn’t just affect your ears - it affects the device itself:

• Whistling or feedback - often caused by wax altering the seal or blocking the receiver
• Muffled or reduced sound output - wax sitting over the microphone or speaker port dampens performance
• False sense of a “broken” hearing aid - many people book a device repair or return to their audiologist when the real issue is a blocked canal, not a fault with the aid
• Increased risk of infection - trapped wax combined with moisture creates a favourable environment for irritation or infection

Why Home Removal Methods Are Riskier Here

Hearing aid users are often more inclined to reach for cotton buds, ear candles or over-the-counter wax removal kits - usually because it feels like a quick fix between audiology appointments. But this group carries extra risk:

• Ear canals altered by long-term mould or dome use can be narrower or more sensitive
• Pushing wax further in makes it harder for it to clear naturally next time
• Aggressive removal attempts increase the chance of irritation exactly where a device needs to sit comfortably

What Professional Removal Looks Like

We use microsuction rather than syringing for hearing aid users, for good reason:

	Microsuction	Ear Syringing (irrigation)
Moisture	Dry procedure - no water introduced	Water-based, can leave residual moisture
Precision	Clinician sees the canal throughout	No direct visualisation
Suitability for hearing aid users	Preferred - avoids moisture near devices/skin already adapted to a mould	Higher risk of irritation or delayed drying complications
Comfort	Generally more comfortable, no vertigo risk	Can trigger dizziness in some patients

A microsuction appointment is quick - typically 15–30 minutes for both ears - and leaves the canal completely dry and clear, ready for your hearing aid to go straight back in.

How Often Should Hearing Aid Users Get Checked?

There’s no universal rule, but as a general guide:

1. Every 3–6 months for regular hearing aid wearers, even without obvious symptoms
2. Sooner if you notice whistling, reduced volume, or a “blocked” sensation
3. Immediately if you experience discomfort, discharge, or a sudden drop in hearing

Regular, proactive removal is far kinder to your ears - and your hearing aid - than waiting until a problem forces the issue.
