What Causes Earwax Build-Up?

Earwax is normal. It helps protect the ear canal by trapping dust, debris and small particles. In many people, wax gradually moves out of the ear naturally. Problems can start when wax does not clear as expected or becomes compacted.

Earwax build-up is common, but it should still be assessed properly. Not every blocked ear is caused by wax, and treatment should only be carried out when it is appropriate.

Why earwax can build up

Several factors can make earwax more likely to collect in the ear canal.

Common reasons include:

• naturally narrow or bendy ear canals
• regular use of earplugs, earbuds or hearing aids
• previous attempts to remove wax with cotton buds
• drier or harder wax
• age-related changes in wax texture
• skin conditions affecting the ear canal
• producing more wax than the ear can naturally clear

Cotton buds are a common problem. They may remove a small amount of surface wax, but they can also push wax further into the ear canal, making blockage more likely.

Symptoms that may be linked to earwax

Earwax build-up can cause symptoms such as:

• a blocked or full feeling in the ear
• reduced hearing
• ear discomfort
• ringing or buzzing sounds
• a sensation of pressure
• hearing aid whistling or reduced hearing aid performance

These symptoms can also have other causes. That is why assessment matters before treatment.

When to arrange an ear assessment

You should consider arranging an ear assessment if symptoms are persistent, affecting hearing, or interfering with day-to-day life.

An assessment helps confirm whether wax is present and whether removal is suitable. If wax is not the cause, you can be advised on the next appropriate step.

The key point
