The ears are important organs. They interpret sound waves for hearing and also help maintain balance in the body.

The ears have a canal that allows for the influx of sound waves and the outflow of earwax.

Unfortunately, there are times when the ears can become clogged due to factors both outside and inside the ear. Clogged ears can affect a person's hearing and sense of balance, as well as cause pain and discomfort.

This article looks at the various causes of clogged ears, some home remedies for the condition, and when to see a doctor.

Some of the more common causes of blocked and clogged ears include:

Barotrauma of the ear

Also known as "airplane ear," this condition occurs when the ear cannot properly pressurize due to the changing air pressure on an airplane.

Ear infection

An ear infection may lead to an increase of fluid production, which may cause the ear to become clogged.

Also known as otitis media, an ear infection occurs when fluid builds up in the ear and a virus or bacteria start to multiply in the fluid. This causes pain and the sensation of clogged ears.

People often experience an ear infection after they have a cold or some other kind of illness that results in increased mucus production in the head.

The extra fluid and mucus can impact the ears and contribute to ear infections.

Earwax impaction

Excess earwax production can cause a buildup of wax that can block the ear canal, creating a sensation of clogged ears.

Wearing hearing aids can lead to earwax impaction because the earwax cannot escape, as easily, due to the placement of the hearing aids.

Foreign object in the ear

Sometimes, small devices a person may use in an attempt to clean their ears, such as cotton swabs, can become lodged in the ear canal.

Children may also stick small items in one of their ears, resulting in a clogging sensation.

Swimmer's ear

This condition occurs when a person's ear is exposed to water, and water becomes trapped in the ear, causing an infection.

Although swimmers most commonly experience this condition, it is possible to get swimmer's ear from the shower or other moist environments.

As a general rule, it is important to use only minimally invasive at-home treatments for clogged ears.

Here are eight tips for unclogging the ears, depending on the cause of the clogging.

Excess earwax

The ears naturally produce earwax. The natural motions of the body, such as chewing and speaking, will usually help guide earwax out of the ear canal.

Sometimes a person produces excess earwax. When this is the case, some at-home treatments include:

1. Softening the wax

Earwax can be too hard and packed to leave the ear canal naturally. When this happens, a few drops of certain liquids, such as baby oil, glycerin, or mineral oil, can help. Putting 2-3 drops in the ear may help soften the wax so it can escape more easily.

2. Ear syringing

Ear syringing can follow softening the wax. A person can purchase a syringing kit at their local drugstore or see their doctor.

About 15 to 30 minutes after putting in drops to soften the earwax, a person can use the syringing kit to introduce water into the ear. The water should be room temperature to avoid dizziness.

A person should never try ear syringing if they have a hole in their eardrum or have ear tubes, which could introduce water deeper into the ear canal.

Airplane ear

If the ears become clogged or painful due to airplane pressure changes, the following steps may help:

3. Valsalva maneuver

This maneuver can help readjust the pressure in the ears.

To perform the maneuver, a person should take in a deep breath, pinch the nostrils shut, close their mouth, and try to exhale against the pinched nostrils. The breath does not have to be overly forceful for this technique to work.

4. Passive techniques

Yawning may help to open up tubes in the ear and ease the symptoms of clogging.

These techniques can passively help open the eustachian tubes that are in the ear and reduce feelings of fullness or clogging.

Examples of passive techniques include:

  • drinking water
  • chewing gum
  • yawning
  • swallowing frequently

5. Earplugs

Some earplugs are marketed toward those who experience airplane ear. These devices have special filters that are designed to promote airflow and equalize pressure in the ears.

While there is no significant scientific evidence showing that they are effective, anecdotal reports suggest that these earplugs can work.

6. Decongestants

Taking a decongestant before flying may help reduce swelling of the mucous membranes that can place further pressure on the ears.

The University of California, Berkeley recommend taking an oral decongestant an hour before departure and another dose an hour before the plane's descent for an extended flight. An airplane's descent is the most common time for ear pressure difficulties.

If you want to buy decongestants, then there is an excellent selection online with thousands of customer reviews.

Swimmer's ear

Keeping the ear clean and dry can help reduce the clogged feeling that occurs with swimmer's ear, an infection of the ear canal.

An individual can use a number of preparations to "dry" the eardrum and prevent infection. Examples include:

7. Rubbing alcohol or alcohol and vinegar

A few drops of rubbing alcohol or a mixture of one part vinegar and one part alcohol can help dry out the ears.

8. Commercial preparations

Many drugstores sell packaged ear drops that are designed to remove water from the ears.

If someone has a hole in their eardrum, they should not use ear drops.

In addition to these tips, a person can use a hair dryer or dry the ears gently with a towel after exposure to water to keep the ear dry.

Wearing earplugs while swimming or bathing can also help reduce the risk of water entering deep into the ear canal.

Some common tools marketed toward earwax removal and unclogging ears may be unsafe and even have the potential to cause hearing loss.

One example is ear candling. This process uses an ear candle, a hollow candle that is inserted into the ear. A person lights the exposed end of the candle and the suction created "pulls" out earwax.

However, people have been injured and burned using ear candles. As a result, the American Academy of Otolaryngology-Head and Neck Surgery do not condone the use of ear candles.

Items such as cotton swabs and bobby pins should not be used to clean the ears. These tools can push earwax further into the ear and introduce new bacteria, dust, or dirt.

A greater risk of using these items is that they may cause cuts to the ear canal that can become infected, or damage the eardrum or the bones of the middle ear.

It is possible to cause more harm when attempting to unclog ears at home. If the ears do not unclog easily, professional medical advice is needed.

The different causes of clogged ears require different treatments.

In many instances, it is best to see a physician to unclog the ears. Sometimes a person can unintentionally cause further harm and damage with at-home methods.

If clogged ears do not resolve easily at home, a person should see their doctor, particularly if they have any of the following symptoms:

  • a fever greater than 101°F in an adult
  • moderate to severe ear pain
  • ear pain that is worsening
  • drainage from the ear that is bloody or filled with pus
  • changes in hearing
  • severe dizziness that does not get better

A doctor will likely ask about the following:

  • the ear symptoms a person has experienced
  • any at-home treatments performed
  • what makes the symptoms worse or better

The doctor will examine the ear using a special tool called an otoscope. This device is designed for insertion into the ear to help the doctor view the eardrum just inside the ear canal.

If the ear is infected, a doctor may prescribe an antibiotic to reduce the bacteria inside the ear.

Unfortunately, there are no known ways to prevent excess earwax buildup that causes clogged ears.

People can practice preventive maintenance by seeing an ear, nose, and throat (ENT) specialist every 6 to 12 months for regular earwax cleanings.

An ENT specialist may also prescribe ear drops that soften the earwax and help prevent buildup.
