Can Earwax Cause Hearing Loss? Facts You Should Know

A blocked ear and muffled hearing can be worrying. You might also notice ringing, itching, or discomfort. One of the most common causes is earwax build-up.

So, can earwax cause hearing loss? Yes, the hearing loss is temporary and improves once the wax is removed.

In this guide, you will learn:

What Is Earwax and Why Do We Have It?

Earwax (cerumen) is a natural substance made by glands inside your ear canal. Its job is to protect your ears from dust, bacteria, and debris. It also keeps the ear canal moisturised and has antimicrobial properties that help prevent infection.

In most people, earwax doesn’t need any help leaving the ear. As you chew or talk, the jaw movement gradually pushes old wax towards the opening of the ear, where it dries up and falls away on its own.

Earwax only becomes a problem when it gets stuck, builds up, and starts blocking the ear canal.

How Does Ear Wax Cause Hearing Loss?

Earwax build-up is natural and harmless in most cases. But when it accumulates faster than the ear can clear it or when it gets pushed in the wrong direction it can affect your hearing. Here is how:

1. Earwax blocks the ear canal

When earwax builds up and hardens, it can form a blockage inside the ear canal. This blockage stops sound waves from passing through to the eardrum, causing muffled or reduced hearing. This is known as conductive hearing loss.

The important thing to know is that this type of hearing loss is almost always reversible. Once the blockage is removed, hearing typically returns to normal.

2. Cotton buds and earbuds can push ear wax deeper

Many people reach for cotton buds to clean their ears, but this usually causes more harm than good. Instead of removing wax, cotton buds push it deeper into the ear canal, where it compacts and becomes much harder to clear naturally.

Wearing earbuds or hearing aids for extended periods can have a similar effect. They block the path that wax normally uses to exit the ear, leading to build-up over time.

If wax becomes packed in tightly, it is unlikely to come out on its own. Professional removal is usually the safest next step.

3. Earwax Can Increase the Risk of Ear Infection

A wax blockage can trap moisture inside the ear canal. Over time, this creates conditions that may increase the risk of an outer ear infection (otitis externa). An infection can cause additional discomfort and make hearing feel even worse until it is treated.

Symptoms of Earwax Build Up

Knowing the warning signs can help you act early and avoid bigger problems. The most common symptoms of excessive earwax are:

These symptoms can sometimes point to other ear problems, not just earwax. If they persist or feel severe, it is always worth getting a professional examination to confirm the cause.

How To Remove Earwax Safely?

The safest option depends on your symptoms and how much wax is present. The first step is an ear examination; this tells you what you’re dealing with before choosing the best method.

Ear drops

For mild earwax build up, ear drops can help loosen wax so it may come out naturally, this includes using olive oil drops. Your hearing may feel worse at first because wax can swell after softening.

Professional Ear Wax Removal Treatment

Professional ear wax removal is the safest and most effective option, especially when ear drops have not helped or the blockage is significant. The most common methods are:

Microsuction: This involves using a gentle suction machine to remove wax while the audiologist views the ear with magnification (microscope or endoscope). It is precise and does not use water.
Ear Irrigation: Ear irrigation uses controlled warm water to flush wax out of the ear canal. It works well for soft wax, but it is not suitable for everyone.
Manual removal with instruments: A clinician may use small instruments to remove wax, especially if it is near the opening of the ear canal. This can also be used alongside microsuction for more precise removal.

Conclusion

Yes, earwax can cause hearing loss. But in most cases, it is temporary and improves once the wax is removed.

If you have blocked ears, muffled hearing, ringing, or discomfort, the safest step is an ear examination. If earwax is the cause, professional removal can clear it quickly and safely. If it is not earwax, you will be guided to the right next step.

At Direct Ear Care, you will be seen by an experienced audiologist who will examine your ears and use the most appropriate removal method for you.

Frequently Asked Questions

Can earwax cause permanent hearing loss?

Earwax blockage usually causes temporary muffled hearing. Hearing improves once the wax is removed. If you have sudden hearing loss, seek urgent medical help.

How do I know if my hearing loss is earwax or something else?

Earwax can cause a blocked feeling and muffled hearing. But similar symptoms can happen with infection or middle ear problems. An ear examination with an otoscope can confirm the cause.

Is microsuction safe for earwax removal?

Yes. Microsuction is considered one of the safest methods available. It uses gentle suction while the clinician views the ear through magnification, giving precise control.

Can I use cotton buds to clean my ears?

No. Cotton buds are one of the most common causes of earwax blockage. They push wax deeper into the canal and can irritate or even damage the delicate skin inside the ear. Clean only the outer ear with a soft cloth.

How often should I clean my ears?

You do not need to clean inside your ears. Clean only the outer ear with a cloth. If you get repeated blockages or wear hearing aids, regular ear checks can help.

Can I remove earwax at home safely?

Only in mild cases, using ear drops, and only if it is safe for you. Never use tools or objects in the ear. If symptoms continue, book a professional ear check.
