Key Takeaways:
- Common signs of ear wax buildup include muffled hearing, a feeling of fullness, tinnitus, earache, and dizziness
- Hearing aid users, older adults, cotton bud users, and people with narrow or hairy ear canals are most prone to wax buildup
- Never attempt self-removal with cotton buds or other objects — these push wax deeper and risk perforating the eardrum
- Use olive oil drops (2-3 drops twice daily for 3-5 days) before a microsuction appointment to soften wax
Recognising Ear Wax Buildup
Ear wax (cerumen) is normal and healthy — it protects the ear canal from dust, bacteria, and water. But when wax builds up excessively, it can cause uncomfortable symptoms. Here’s how to recognise when buildup needs professional attention.
Common Signs of Wax Buildup
Hearing Loss or Muffled Hearing
The most common symptom. When wax blocks the ear canal, sound can’t reach the eardrum effectively. You might notice:
- Conversations seem quieter or harder to follow
- You’re turning up the TV or phone volume
- One ear seems worse than the other
- Hearing improves temporarily after a shower (warmth softens wax briefly)
Feeling of Fullness
A sensation of pressure or fullness in the ear, as if something is blocking it. This is often described as the ear feeling “plugged” or “stuffed.”
Tinnitus
Ringing, buzzing, humming, or whooshing sounds in the ear. Wax pressing on the eardrum or ear canal walls can trigger tinnitus symptoms.
Earache
Discomfort or pain in the ear, which may be:
- A dull ache
- A feeling of pressure
- Sharp pain if wax is pressing on the eardrum
- Worse when lying on the affected side
Itching
Itchiness inside the ear canal is common with wax buildup. Resist the urge to scratch with cotton buds or other objects — this makes the problem worse.
Dizziness
In some cases, wax buildup can affect balance by putting pressure on the eardrum or stimulating the ear canal’s nerve supply.
Cough
Surprisingly, ear wax buildup can trigger a cough reflex. The ear canal shares a nerve supply (Arnold’s nerve) with the throat, and stimulation from wax can cause a dry, persistent cough.
Who Is More Prone to Wax Buildup?
Some people produce more wax or have ear canal shapes that make natural wax migration difficult:
- Hearing aid users — Aids push wax back and block natural migration
- Earbud/earphone users — Same effect as hearing aids
- Older adults — Wax tends to become drier and harder with age
- People with narrow ear canals — Less room for natural migration
- People with hairy ear canals — Hair can trap wax
- People who use cotton buds — Push wax deeper, stimulate more production
- People with skin conditions — Eczema or psoriasis in the ear can affect wax
When to See a Professional
See a clinician if you experience:
- Hearing loss that doesn’t improve after a few days of olive oil drops (learn how often ear wax removal may be needed)
- Pain in the ear
- Discharge from the ear (which could indicate infection, not just wax)
- Tinnitus that persists
- Dizziness or balance problems
- Symptoms in only one ear (to rule out other causes)
- Any symptoms after ear surgery or with a known perforation
Don’t try to remove wax yourself with cotton buds, hairpins, keys, or any other objects. These can push wax deeper, damage the ear canal, or perforate the eardrum.
What to Do Before Your Appointment
If you’ve booked a microsuction appointment:
- Use olive oil drops — 2–3 drops twice daily for 3–5 days before
- Don’t use cotton buds — They will make things worse
- Note your symptoms — Duration, severity, affected ear(s)
- Bring your medical history — Previous ear problems, surgeries, medications
Can Wax Buildup Cause Permanent Damage?
Wax buildup itself rarely causes permanent harm. However:
- Untreated impaction can lead to infection
- Self-removal attempts can cause injury
- Prolonged hearing loss can affect cognitive function in older adults
- Chronic impaction can mask underlying conditions
The solution is simple: professional removal by microsuction, followed by a maintenance routine to prevent recurrence.
