Question 1

What is the medical term for ear wax?

Accepted Answer

The medical term for ear wax is cerumen. You may also see it referred to as "ceruminous secretion" in clinical settings, but cerumen is the standard term used by doctors, audiologists, and nurses.

Question 2

Why do we have ear wax?

Accepted Answer

Ear wax protects the ear canal by trapping dust, debris, and bacteria before they reach the eardrum. It also has natural antibacterial properties and keeps the skin inside the ear canal lubricated, preventing dryness and irritation.

Question 3

What causes ear wax to become hard?

Accepted Answer

Ear wax naturally loses moisture the longer it sits in the ear canal, which is why hardened wax is more common in older adults and in people who don't produce or clear wax efficiently. Frequent use of hearing aids, earphones, or cotton buds can also contribute, as these can stop wax moving out of the ear naturally.

Question 4

Can ear wax be a liquid?

Accepted Answer

Yes — freshly produced ear wax is typically soft and can appear quite liquid or sticky, especially in people with the "wet" earwax gene type. This is completely normal and isn't a sign of infection on its own, though sudden changes in colour, smell, or consistency are worth having checked.

Question 5

What do doctors use to check for ear wax?

Accepted Answer

Clinicians typically use an otoscope — a handheld instrument with a light and magnifying lens — to look into the ear canal and check for wax build-up, before deciding whether removal is needed and which method (microsuction or irrigation) is most appropriate.

Question 6

Is ear wax build-up the same as an ear infection?

Accepted Answer

No. Build-up on its own is just excess wax in the canal — uncomfortable, but not an infection. However, untreated build-up can occasionally create the conditions for infection, which is why persistent symptoms are worth having checked rather than ignored.
