Ear wax is a normal and useful part of a healthy ear. It helps protect the ear canal and usually leaves it naturally. Yet some people find their ears becoming blocked again, even after having wax professionally removed. The most common explanation is not that their ears make an unusual amount of wax, but that the wax cannot move out efficiently.
What is ear wax and why do we make it?
Ear wax is also called cerumen. It is a mixture of waxy and oily secretions from glands in the outer ear canal, along with dead skin cells and small particles of dust. It lubricates the skin, traps debris and contributes to the ear’s natural defences. Producing some wax is healthy: the aim is to prevent troublesome build-up, not to make your ears completely wax-free.
The skin inside the ear canal slowly moves outwards as it renews itself. This carries old wax towards the opening, where it usually dries and falls away. Talking and chewing may help this natural movement. Most people do not need to clean inside their ear canals at all.
Why does ear wax build up again?
Your ears continue making new wax after a blockage is removed. A fresh blockage happens when wax accumulates faster than the ear’s self-cleaning process can move it out. Several everyday factors can make this more likely, and it is common to have problems in just one ear.
1. Narrow, curved or hairy ear canals
The shape of the canal can make it harder for wax to travel towards the opening. Some people have naturally narrow or winding canals, while others have more hair in the outer canal. Neither is necessarily a health problem, but both can make recurrent blockages more likely.
2. Dry or hard wax
Wax may become drier and less able to move naturally as we get older. Hard wax can collect and form a compact plug. However, impacted wax can occur at any age, including in children.
3. Hearing aids, earbuds and earplugs
Devices worn in the ear canal can sometimes interrupt the natural outward movement of wax. Repeated insertion may push existing wax further in. This does not mean people should stop using their hearing aids or hearing protection; keeping the devices clean and having the ears checked when necessary is more helpful.
4. Irritated or inflamed skin
Eczema, dermatitis or inflammation inside the ear canal can alter the amount of shed skin and debris mixed with wax. Itching, soreness or discharge may mean that the problem is not simply a wax blockage, so an examination is important.
What makes ear wax problems worse?
Cotton buds are a common culprit. They may wipe away a little wax at the entrance but can push the rest deeper, turning loose wax into a plug. Fingernails, hairpins and home ear-cleaning tools can also damage or irritate delicate canal skin.
Water from swimming or showering can sometimes make an existing wax plug swell temporarily, leaving the ear feeling suddenly blocked. Repeatedly inserting in-ear headphones or earplugs may also contribute in people prone to wax build-up. Ear candles and unregulated home suction devices are not recommended, and there is no good evidence that a particular diet or supplement prevents normal wax production.
Does microsuction or irrigation cause more wax?
Professional wax removal does not normally make the ear produce extra wax. If you have narrow canals, hard wax or regularly use in-ear devices, those underlying factors will still be present after treatment. Some people may not need removal again for years; others notice recurring symptoms more often. There is no single safe timetable that suits everybody.
How can I reduce repeat blockages?
- Leave the inside of the canal alone: clean only the outside with a soft cloth; avoid cotton buds and tools.
- Ask about wax-softening drops: a pharmacist or clinician can advise if they are suitable. Do not use drops with a known or suspected perforation, discharge or infection unless a clinician specifically advises it.
- Care for hearing aids and earmoulds: follow the manufacturer’s instructions for domes, wax filters and earmoulds.
- Get the ear examined when symptoms return: not every blocked ear is caused by wax, and repeated treatments are not always necessary.
When should I have my ears checked?
It is worth arranging an examination if your ear feels blocked, hearing seems muffled, or wax repeatedly causes problems. Pain, persistent discharge, bleeding or dizziness needs appropriate assessment. Sudden hearing loss requires urgent medical attention and should not be assumed to be caused by wax.
At Wigan Hearing in Standish, we examine the ear before recommending removal and choose an appropriate method where treatment is suitable. We also see children aged five and over for ear wax assessment and removal, subject to clinical suitability. We do not provide hearing tests for children. Please contact us first if you are unsure whether an appointment is appropriate for your child.
Can recurring ear wax be prevented completely?
Usually not—and it would not be desirable to stop healthy wax production. The aim is to avoid pushing wax deeper, minimise irritation and deal with problems safely. A professional ear examination is more useful than assuming every blocked feeling is another build-up of wax.
