What is earwax buildup?
In short Earwax (cerumen) protects the ear canal. Buildup occurs when wax doesn’t clear out and blocks the canal, often causing muffled hearing, fullness, itching, or feedback with hearing aids.
Why it matters: Blocked ears can worsen communication and balance. Removal usually gives immediate relief.
Urgent warning signs
- Severe pain, fever, or drainage that smells bad
- Sudden hearing loss, spinning dizziness, or facial weakness
- After head injury: blood/fluid from ear
- Known eardrum perforation or ear surgery history
These need prompt medical assessment.
Common symptoms
- Muffled hearing or a blocked, “underwater” feeling
- Fullness, pressure, itching, or mild earache
- Ringing (tinnitus) or hearing aid feedback/whistling
- Worse after shower or swimming (wax swells with water)
Related topics
Why it happens (older adults)
Wax & skin changes
- Wax gets drier and thicker with age
- Slower skin migration outward from the eardrum
Blockers
- Hearing aids, earbuds, cotton swabs push wax inward
- Narrow or bendy canals (anatomy), hair in the canal
Safe at-home care
Softening drops (choose one)
- Mineral oil or baby oil: 3–5 drops once daily for 3–5 days
- Carbamide peroxide OTC: per label (usually 5–10 drops, 1–2×/day up to 4 days)
- Saline or glycerin-based drops if sensitive
Lie on your side 5–10 minutes after drops to let them work.
Gentle rinse (only if eardrum is normal)
- After softening, a warm (body-temp) saline bulb-syringe rinse may help
- Stop if pain, dizziness, or ringing occurs
If you have eardrum perforation, ear tubes, or ear surgery history, avoid rinsing and see a clinician.
What NOT to do
- No cotton swabs, keys, hairpins — they push wax deeper and can injure the ear
- Avoid ear candling (ineffective, burn/injury risk)
- Don’t use cold or very hot water (dizziness, injury)
- Don’t rinse if you have ear pain, drainage, prior eardrum issues, or tubes
Hearing aids & earwax
- Clean wax guards and domes regularly (per device guide)
- Power off aids before inserting drops; wipe shells daily
- Consider monthly wax checks if you’re prone to blockage
How clinicians check
Ear exam
- Otoscopy to look for wax, infection, or a perforation
- Assessment of canal shape, skin, and eardrum
Hearing
- Simple office hearing screen; full audiology if needed
- Post-removal hearing usually improves immediately if wax was the cause
Removal options
Microsuction (clinic)
- Wax is removed under direct view with a small suction tube
- Good if you have eardrum issues, diabetes, or narrow canals
Manual removal
- Loop/curette under magnification; quick for firm wax near the opening
Irrigation (clinic)
- Warm water/saline with controlled pressure; not used if perforation suspected
Prevention & upkeep
- If prone to buildup, use mineral oil 2–3 drops weekly after shower
- Schedule a quick ear check every 6–12 months, or sooner with hearing aids
- Dry outer ear gently with a towel; do not insert swabs
When to contact a clinician
- No improvement after 3–5 days of softening drops
- Severe pain, drainage, fever, or sudden hearing change
- Use hearing aids and symptoms recur often
- History of ear surgery, perforation, or frequent infections
Quick answers
How long to use softening drops?
Usually 3–5 days. If not improved, book a removal visit.
Is olive oil okay?
Yes for softening in many people. If irritation occurs, switch to mineral oil or saline-based drops.
Do I need antibiotics?
Not for simple wax. Antibiotic drops are only for bacterial infections diagnosed by a clinician.
Why does it come back?
Age-related changes, canal anatomy, and hearing aids push wax inward. Regular maintenance helps prevent blockages.
