Blocked ears and earwax: what helps, and what makes it worse
A blocked ear is most often caused by earwax, but it can also be middle ear fluid, a cold, or a sudden hearing loss that needs urgent attention. Never use cotton buds, ear candles or sharp objects, all of which push wax deeper or damage the canal. If the blockage does not clear within a few days, or comes with pain, discharge, dizziness or hearing loss, have the ear examined.
Earwax has a bad reputation it does not deserve. It is protective, antibacterial and self-clearing, and the ear is designed to move it outward without any help. Most problems start when people help, which is why how to remove ear wax is the wrong question to start with.
Why ears block
The most common reason is wax that has been compacted rather than removed, usually by a cotton bud. Narrow or hairy ear canals, hearing aid or earphone use, and simply producing more wax than average all make it more likely. But wax is not the only cause of an ear that feels full: middle ear fluid after a cold, pressure changes from flying, and sudden sensorineural hearing loss can all feel identical from the outside.
That last one is the reason this is worth taking seriously. A blocked feeling that is actually a sudden hearing loss is time-critical.
What not to do
- Cotton buds. Cotton bud ear damage is real: they compact wax against the eardrum and are the leading cause of the problem they are used to solve.
- Ear candles. There is no evidence they remove wax, and they carry a real burn risk.
- Hair pins, keys, matchsticks or anything else rigid. The canal skin is thin and the eardrum is close.
- Repeated over-the-counter drops for weeks on end without knowing what is actually blocking the ear.
What can help
If you are confident it is wax and there is no pain, discharge or history of perforation, softening drops used as directed for a few days will often let the ear clear itself. Keep water out while the ear feels blocked, and do not fly with a badly blocked ear if you can avoid it. If it has not resolved in a week, stop experimenting and get it looked at.
When to seek help promptly
- Sudden hearing loss, which is treated as urgent
- Pain, discharge or bleeding
- Dizziness or severe tinnitus in that ear
- Blockage in one ear only that persists
- Any suspicion of a perforated eardrum, or previous ear surgery
Hearing aid wearers
If you wear hearing aids, wax matters twice over: once in your ear and once in the device. Reduced or muffled sound in one aid is very often a blocked wax filter rather than a fault. Checking the filter first saves a lot of unnecessary worry.
Get the ear checked
Ears To You is a mobile audiology service, so an examination and hearing assessment can happen at home rather than in a clinic. If a blocked ear is affecting your hearing, or you are weighing up earwax removal in Sydney and are not sure whether it is wax at all, call 02 7900 5551 and we will advise on the appropriate next step.
Key facts
- Earwax is protective and self-clearing; the ear canal moves wax outward without intervention.
- Cotton buds are a leading cause of compacted earwax and should not be used to clean ears.
- There is no evidence that ear candles remove wax, and they carry a burn risk.
- A blocked feeling can also indicate middle ear fluid or sudden sensorineural hearing loss, which requires urgent attention.
- In hearing aid wearers, muffled sound in one device is often a blocked wax filter rather than a fault.
- Ears To You provides mobile hearing assessments at home. Call 02 7900 5551.
Frequently asked questions
What causes a blocked ear?
Most often compacted earwax, but also middle ear fluid after a cold, pressure changes from flying, or a sudden hearing loss, which feels similar but is urgent.
Should I use cotton buds to clean my ears?
No. Cotton buds compact wax against the eardrum and can damage the canal. They are a leading cause of the blockages people use them to treat.
Do ear candles work?
No. There is no evidence that ear candling removes wax, and it carries a genuine burn risk.
When should a blocked ear be checked?
If it has not cleared within about a week, or if there is sudden hearing loss, pain, discharge, dizziness or severe tinnitus, or the blockage is in one ear only.
My hearing aid sounds muffled. Is it wax?
Very likely. Check and replace the wax filter before assuming the device has failed.
