Ear wax, known medically as cerumen, is not dirt. It is a natural, protective substance that traps dust, keeps the ear canal moisturised, and helps guard against infection. In most people the ear is self-cleaning, and wax gradually works its way out on its own. Problems usually arise only when we interfere with this natural process.
Why does wax build up?
Some people simply produce more wax than others. Build-up is also more likely if you use cotton buds, wear hearing aids or earphones, or have narrow or hairy ear canals. Ironically, the most common cause of a blockage is cotton buds, which push wax deeper rather than removing it.
Signs of a blockage
A plug of wax can cause a feeling of fullness, muffled or reduced hearing, mild earache, ringing in the ear, or occasional dizziness. These symptoms can come on gradually, so people often do not realise wax is the cause.
What you can safely do at home
For mild build-up, over-the-counter ear drops such as olive oil or sodium bicarbonate drops can soften the wax over a few days and help it clear naturally. Gently warming the oil to body temperature before use is more comfortable. Wiping the outer ear with a cloth is fine.
What to avoid
Never insert cotton buds, hair grips, or any object into the ear canal, as this pushes wax deeper and risks injuring the eardrum. Ear candling is not effective and can cause burns. Avoid forceful home syringing kits if you have ever had a perforated eardrum or ear surgery.
When should you see a doctor?
See an ENT specialist or your doctor if home drops do not help, if you have pain, discharge, bleeding, or sudden hearing loss, or if you have a history of ear problems. In the clinic, wax can be removed safely and comfortably using microsuction or professional irrigation.
The key message is simple: leave your ears alone as much as possible, soften stubborn wax with drops, and seek professional help rather than digging it out yourself.
