Why You Should Never Use Cotton Buds to Clean Your Ears

Cotton buds are the most common way people clean their ears — and the most dangerous. Here's what the science says, and what to do instead.

The Surprising Purpose of Ear Wax

Ear wax—known medically as cerumen—often gets a bad reputation. Most people see it as something dirty that needs to be removed. In reality, it's one of your body's most effective natural defences.

Your ear canal produces cerumen to trap dust, bacteria, dead skin cells, and other microscopic debris before they reach the delicate eardrum. It also moisturises the sensitive skin inside your ear canal, preventing dryness and itching. Without it, your ears would be far more vulnerable to infection.

Your ears are self-cleaning. As you chew, talk, and move your jaw throughout the day, old wax gradually migrates outward toward the opening of the ear, where it dries and falls away naturally. It's an elegant system that requires no intervention.

Why Cotton Buds Cause More Harm Than Good

Despite what many of us were taught growing up, inserting a cotton bud into your ear canal is one of the worst things you can do for your hearing health. Here's why.

Rather than removing wax, cotton buds push it deeper into the ear canal. Over time, this compacts the wax against the eardrum, creating a hard plug known as impaction.

Impacted wax can cause muffled hearing, a persistent feeling of fullness, tinnitus, dizziness, and even pain.

The ear canal is only about 2.5 centimetres long and lined with extremely thin, delicate skin. A cotton bud can easily scratch this lining, creating micro-tears that invite bacterial or fungal infections. In more serious cases, pushing too far can perforate the eardrum—a painful injury that may require surgery.

⚠️ The NHS is clear: never insert anything into your ear canal, including cotton buds, fingers, pen caps, hair grips, or any other objects.

What About That Satisfying Feeling?

If you've ever cleaned your ears with a cotton bud and felt a pleasant sensation, there's a reason for that. The ear canal is rich in nerve endings, including a branch of the vagus nerve. Stimulating this area can trigger a mild pleasurable response—sometimes even a cough reflex.

This sensation isn't a sign that you're doing something beneficial. It's simply a neurological response. Chasing it regularly can lead to a cycle of irritation, overproduction of wax, and increasing discomfort.

Safe Ways to Manage Ear Wax at Home

For most people, the best approach is to do nothing at all. Let your ears clean themselves. When you shower or bathe, simply wipe the outer ear with a damp cloth—never go inside the canal.

Using Ear Drops

If you're prone to wax buildup, you can use olive oil or sodium bicarbonate ear drops. Here's how:

  1. Apply two to three drops into the affected ear
  2. Lie on your side for a few minutes to let the drops work their way in
  3. Repeat twice a day for three to five days
  4. The wax will soften and move out naturally

You can find these drops at any pharmacy without a prescription.

Avoid ear candles—there's no scientific evidence they work, and they carry a genuine risk of burns and further wax deposits.

When to See a Professional

Sometimes home care isn't enough. Seek professional help if you experience any of the following:

  • A sudden or noticeable drop in hearing
  • A feeling of pressure or blockage that persists after using drops
  • Ringing, buzzing, or humming in one or both ears
  • Ear pain or discharge
  • Dizziness or balance problems
  • What is microsuction?

Professional ear wax removal—particularly microsuction—is the safest and most effective method available. During microsuction, a trained clinician uses a gentle suction device under magnification to carefully remove wax without water and without touching the eardrum. The procedure takes just a few minutes and provides immediate relief.

Prevention Is Simple

Keep your ears healthy with a few straightforward habits:

  • Resist the urge to insert anything into your ears
  • Use olive oil drops once a week if you tend to produce excess wax
  • Dry your ears gently after swimming or bathing
  • If you wear hearing aids, schedule a professional wax check every six months—hearing aids can accelerate buildup by blocking the natural exit path
Your ears are remarkably good at looking after themselves. The best thing you can do is let them.
