Earwax and Hearing: When It’s Normal vs When It’s a Problem
Earwax is normal, but buildup can affect hearing. Learn safe do’s and don’ts, when to get it checked, and what clinics usually do.
Why earwax exists
Earwax protects the ear canal and helps trap dust and debris.
Most of the time, the ear naturally clears wax over time.
Signs of problematic buildup
- Sudden muffled hearing
- A feeling of fullness or pressure
- Itchiness or mild discomfort
- New hearing aid feedback (whistling)
- Ringing (tinnitus) that started around the same time
Avoid these common mistakes
- Cotton swabs (they can push wax deeper)
- Ear candles
- Sharp tools or DIY scraping
What a clinic might do
Look in your ear with an otoscope to confirm wax is the issue.
Recommend drops/softening first (depending on your situation).
Remove wax safely using suction, irrigation, or instruments — the best method depends on your ear and medical history.
When to get assessed sooner
- Severe ear pain, drainage, fever
- Sudden hearing loss (especially in one ear)
- Dizziness/vertigo
- You have ear surgery history or a known perforated eardrum
