What is earwax buildup?
Your ear canal produces a waxy oil called cerumen, which is more commonly known as earwax. This wax protects the ear from dust, foreign particles, and microorganisms. It also protects ear canal skin from irritation due to water. In normal circumstances, excess wax finds its way out of the canal and into the ear opening naturally, and then is washed away.
When your glands make more earwax than necessary, it may get hard and block the ear. When you clean your ears, you can accidentally push the wax deeper, causing a blockage. Wax buildup is a common reason for temporary hearing loss.
You should take great caution when trying to treat earwax buildup at home. If the problem persists, visit your doctor. Treatment is generally quick and painless, and hearing can be fully restored.
Causes of earwax buildup
Some people are prone to produce too much earwax. Still, excess wax doesn’t automatically lead to blockage. In fact, the most common cause of earwax blockage is at-home removal. Using cotton swabs, bobby pins, or other objects in your ear canal can also push wax deeper, creating a blockage.
You’re also more likely to have wax buildup if you frequently use earphones. They can inadvertently prevent earwax from coming out of the ear canals and cause blockages.
Signs and symptoms of earwax buildup
The appearance of earwax varies from light yellow to dark brown. Darker colors don’t necessarily indicate that there’s a blockage.
Signs of earwax buildup include:
sudden or partial hearing loss, which is usually temporary
tinnitus, which is a ringing or buzzing in the ear
a feeling of fullness in the ear
earache
Unremoved earwax buildup can lead to infection. Contact your doctor if you experience the symptoms of infection, such as:
severe pain in your ear
pain in your ear that doesn’t subside
drainage from your ear
fever
coughing
persistent hearing loss
an odor coming from your ear
dizziness
It’s important to note that hearing loss, dizziness, and earaches also have many other causes. See your doctor if any of these symptoms are frequent. A full medical evaluation can help determine whether the problem is due to excess earwax or another health issue entirely.
Earwax in children
Children, like adults, naturally produce earwax. While it may be tempting to remove the wax, doing so can damage your child’s ears.
If you suspect your child has earwax buildup or a blockage, it’s best to see a pediatrician. Your child’s doctor may also notice excess wax during regular ear exams and remove it as needed. Also, if you notice your child sticking their finger or other objects in their ear out of irritation, you might want to ask their doctor to check their ears for wax buildup.
Earwax in older adults
Earwax can also be problematic in older adults. Some adults may let wax buildup go until it begins obstructing hearing. In fact, most cases of conductive hearing loss in older adults are caused by earwax buildup. This makes sounds seem muffled. A hearing aid can also contribute to a wax blockage.
How to get rid of excess earwax
You should never attempt to dig out earwax buildup yourself. This can cause major damage to your ear and lead to infection or hearing loss.
Only use cotton swabs on the outer portion of your ears if necessary.
Softening earwax
To soften earwax, you can purchase over-the-counter drops made specifically for this purpose. You can also use the following substances:
mineral oil
baby oil
glycerin
Ear irrigation
Another way to remove earwax buildup is by irrigating the ear. Never attempt to irrigate your ear if you have an ear injury or have had a medical procedure done on your ear. Irrigation of a ruptured eardrum could cause hearing loss or infection.
Never use products that were made for irrigating your mouth or teeth. They produce more force than your eardrum can safely tolerate.
To remove wax buildup, your doctor may use:
irrigation
suction
a curette, which is a small, curved instrument
Follow your doctor’s instructions for aftercare carefully.
Most people do well after earwax removal. Hearing often returns to normal immediately. However, some people are prone to produce too much wax and will face the problem again.
What’s the outlook?
While sometimes bothersome, earwax is a natural part of your ear health. You should avoid removing earwax with objects because this can worsen the problem. In severe cases, cotton swabs can even damage the eardrum or ear canal.
Medical help is usually only necessary when you have excess earwax that doesn’t come out on its own. If you suspect you have earwax buildup or blockage, see your doctor for assistance.
