In humans, the ear naturally produces a waxy substance called cerumen (1), which we commonly refer to as earwax. It has some vital uses, and hence removing it is not required. But if the wax is thick and hardened, it could cause ear pain. In such a case, pediatric,ENT or family doctor, consultation is a wise step to decide on a course of action.

Read this MomJunction article for the information you need about earwax in babies and ways to attend to it.

Why Do Babies Have Earwax?

Earwax is naturally produced by the outer ear canal, which lies between the earlobe and the eardrum of the middle ear (2). It may seem like an unnecessary biological waste but has its uses, such as these (3):

  • Waterproofs the ear canal
  • Acts as a sticky trap for dust and insects
  • Lubricates the ear canal to prevent irritation
  • Ear wax is made of compounds that have antibacterial and antifungal properties
  • Ear wax is produced only in the outer ⅔ of the ear canal

So, should you let the wax be or remove it?

Should You Clean Baby’s Ear Wax Regularly?

The American Academy of Pediatrics recommends not to clean a baby’s earwax at home using a cotton bud or ear drops (4). Even doctors recommend that if earwax is not causing pain or blocking the ear canal, it should be left alone.

You must only clean the outer ear using a soft cloth soaked in warm water. Run the cloth around the rims of the external ear and avoid ear cleaning techniques such as ear flushing, pouring hydrogen peroxide, mineral oil, etc. into the ear canal. It might complicate the condition.

However, sometimes there could be excessive earwax production in babies that might lead to blockage of the ear canal, causing pain.

What Causes Earwax Buildup In Babies?

There is no single reason for earwax buildup in infants. The following, however, are a few common causes of earwax complications among infants (5):

  • Excess earwax secretion: In about 5% of children, there is excess earwax secretion, which can cause more wax accumulation than usual.
  • Pushing objects into the ear canal: Putting objects in the baby’s ear canal pushes the earwax deeper.
  • Repeatedly insertion of finger into ear canal: A baby’s ear canal is narrow and small. Putting a finger inside it frequently could pack the earwax within. Therefore, never use your finger to clean the baby’s ear and discourage the infant from sticking their finger into the ear.
  • Extended use of hearing aids or earplugs: Hearing aids and earplugs block the entrance of the ear canal, which prevents the wax from shedding. If your baby wears a hearing aid or earplugs for several hours in a day, then they could be at risk of developing hardened ear wax.
  • Use of cotton swab : Cotton swabs, also called cotton buds, cotton tips, or Q-tips, are not ideal for removing earwax, and medical experts recommend against its use. A cotton bud can push the earwax deep into the ear canal, causing it to get stuck and cause irritation to the ear canal itself.

Earwax secretion may seem like a trivial thing, but it could cause discomfort and pain to infants and toddlers, who may then display certain symptoms.

What Are The Symptoms Of Excess Earwax Buildup In Babies?

Accumulation of earwax in the ear can lead to the symptom mentioned here (6).

  • Older infants and toddlers may point at their ears to indicate that something is wrong with it. Ear wax can harden and cause the sensation of something being stuck within the ear canal.
  • Earwax impaction can obstruct the ear canal, causing hearing difficulties.
  • If the earwax accumulation is very severe, you may even see a bit of hardened wax sticking out from the ear canal of the baby.
  • Severe symptoms of earwax accumulation include pain, fussiness, and sometimes even dizziness.

Take your baby to a doctor if any of these symptoms are evident. Excess hardened earwax can increase pressure on the eardrum, causing further complications.

Can Earwax Cause Problems In Babies?

Yes, but only when it gets hard and impacted. Ear wax gradually moves to the opening of the ear and sheds itself in small quantities. In some cases, hardened earwax that lodges too deep into the ear canal can create problems for the infant. These problems could be:

  • Itching
  • Ear pain
  • Poor hearing
  • Tinnitus

Prompt removal of excessive earwax from the baby’s ear is essential to avoid these problems. However, it must be performed by medical or nursing specialist  who has been trained appropriately for it.

How Is Excess Earwax In Babies Removed?

In cases where excessive earwax is causing issues, a doctor will use the following methods to get rid of excess wax.

  • Ear drops, which you have to administer at least once in a day to soften the earwax and make it shed. The number of drops and the duration of treatment depends on the extent of the earwax accumulation. You will need to make the baby lie down, turn the affected ear upwards, and pour the drops into the canal, then press the litte skin flap in front of the ear so that the ear drops go ino the ear canal.

Hold the baby in the lying position for a few minutes before letting them sit up. Loosened earwax will come out on its own and should not be prodded using a finger or cotton bud. Earwax-softening drops are available over the counter too, but one must never use them for babies unless prescribed or advised by the doctor. The American Academy of Pediatrics advises parents to only use products that are FDA-approved (7).

  • Ear irrigation: Ear irrigation or syringing is a medical procedure of earwax removal in which warm water is squirted into the baby’s ear. This weakens and dislodges the wax out of the ear with water (8).
  • Microsuction: A small suction tube (“hoover”) is used to suck the ear wax out of the ear canal under the use of a good light source and us magnification.
  • Manual earwax removal may be necessary if the earwax is stubbornly hard. Ear, Nose, Throat (ENT) doctors have a specialized set of tools to safely extract the earwax manually. The child has to be still for the procedure, so a parent will have to hold the baby. Very rarely, when the infant is unable to lie still, or if the earwax is very hard to cause pain during extraction that the doctor may consider using general anesthesia to the baby.

In case the baby already had an infection within the ear canal, the doctor may prescribe an antibiotic after the earwax removal procedure.

How To Prevent Earwax Problems In Babies?

Bathing is enough to loosen the wax and get it out. However, some steps could help prevent earwax problems in babies (1).

  • Never use cotton swabs: Cotton swabs are widely discouraged for use by medical professionals because they push the earwax deeper into the ear canal. Since the ear canal has a self-cleaning property, there is no need to remove the earwax manually. Also, the wax serves a purpose and is not the body’s waste product.
  • Do not try removing earwax with finger or object: If you see earwax accumulated inside your baby’s ear, then do not try picking it out. You may cause the wax to slide deeper while also increasing the risk of eardrum injury.
  • Remove hearing aids when the bay is asleep: If your baby wears hearing aids, then take them off when asleep or other intervals as discussed with the audiologists. It will allow the shedding of earwax and prevents accumulation. Sometimes it is necessary to use some softening ear drops every night when the hearing aids are not used to support the process.Limit the earplug usage, if you’ve been using them for the baby for some reason.
  • Check ears : You may wanat to check your baby’s ears every time after a bath. It allows you to notice any early accumulation of earwax inside the ear canal but if you see the ear wax coming out by itself, it should be a good sign that they are self- cleaning. These observations are even more essential when the baby wears hearing aids.

Taking the baby to the doctor for a checkup can also help identify if the problem is due to earwax or an infection.

How To Differentiate Between Earwax Buildup And Ear Infection?

A baby with an ear infection might display symptoms similar to that of earwax accumulation. However, ear infections also cause other symptoms such as fever, fluid discharge from the ear, earache, poor appetite, and unexplained crying with fussiness (9) (10). The earwax is also smelly in the case of an infection.

Check the ear canal for yellowish-brown spots, which is the natural color of wax. If you notice redness, dampness, yellowish or green discharge, then it is quite likely to be an ear infection.

Remember that the ear canal can take care of cleaning away the excess earwax, and there is no need to rid the ears of earwax manually. Just be watchful of any signs of earwax accumulation and consult a doctor to ensure that it does not negatively impact the baby’s health.
