Earwax Build-Up: Safe Ways to Remove It at Home and When to See a Nurse

Earwax is not dirt. It protects your ears, traps dust and keeps the ear canal from drying out. Most ears clean themselves. But sometimes wax builds up and blocks the canal, and the things people reach for first, like cotton buds, usually make it worse.

Imagine stepping out of the shower and suddenly one ear sounds like it’s underwater. Voices are muffled, you hear a faint ringing, and the ear feels full. You grab a cotton bud and dig around, and it gets even worse. That’s because you’ve just pushed the wax deeper. There’s a gentler fix, and it starts with a few drops of oil.

Signs of earwax build-up

• Muffled hearing or hearing loss in one or both ears
• A feeling that the ear is full or blocked
• Earache or itching
• Ringing or buzzing (tinnitus)
• Dizziness

Build-up is more likely if you wear hearing aids or earplugs, have narrow or hairy ear canals, are older, or often use cotton buds.

The safe home method

The UK’s NHS recommends softening the wax with olive or almond oil:

1. Lie on your side with the blocked ear facing up.
2. Put 2 to 3 drops of olive or almond oil into the ear.
3. Stay lying down for 5 to 10 minutes.
4. Repeat 3 to 4 times a day for 3 to 5 days.

Over about two weeks, small lumps of wax should work their way out, often at night. A pharmacist can also recommend ear drops that soften or dissolve wax.

Don’t use drops if you have a perforated (holed) eardrum, grommets, or ear pain with discharge. Don’t use almond oil if you’re allergic to almonds.

What not to do

• No cotton buds, hairpins or fingers in the ear canal. They push wax deeper and can scratch the canal or damage the eardrum.
• No ear candles. There is no evidence they remove wax, and they can cause burns. The US Food and Drug Administration has warned against them.
• Be wary of home ear vacuums and camera scoops. There’s no good evidence they help, and used wrongly they can injure the ear.

Professional earwax removal

If drops haven’t worked after about five days, a nurse, doctor or audiologist can remove the wax using:

• Microsuction: a tiny suction device used while looking into the ear with a microscope
• Irrigation: gently flushing the ear with water using an electronic irrigator
• Manual removal: a small instrument called a curette or hook

These are usually painless. Availability and cost vary by country and clinic, so ask your local surgery, clinic or pharmacy what they offer.

But what if it isn’t wax at all?

Not every blocked ear is wax. See a doctor or nurse promptly if you have ear pain with fever, discharge or blood from the ear, swelling around the ear, or symptoms that keep coming back. Sudden hearing loss in one ear with no obvious cause is urgent: get seen the same day, because early treatment can protect your hearing.
