Earwax buildup: safe removal and when to see a clinician

The short answer

Most earwax should be left alone. The ear cleans itself, and the AAO-HNS guideline tells clinicians not to routinely treat earwax in people who have no symptoms and whose ears can be examined ^[1].

Treat it when it's causing trouble. The guideline defines cerumen impaction as wax buildup that causes symptoms, prevents a needed look at the ear, or both, and says it should be treated or referred when found ^[1].

What to skip: cotton swabs and other small objects ^[3], and ear candles ^[1][4].

What earwax does, and why it builds up

Earwax (cerumen) is made by glands in the outer third of the ear canal. It protects and lubricates the canal and has antibacterial properties. Jaw movement from talking and chewing helps move old wax outward, where it dries and falls out ^[5].

How common is buildup? According to the guideline's authors, excessive or impacted earwax is present in about 1 in 10 children, 1 in 20 adults and more than one-third of older adults and people with developmental disabilities ^[2]. About 12 million people in the U.S. seek care for earwax problems each year, and about 8 million removal procedures are performed ^[3].

What makes it worse:

• Swabs and probing. Repeatedly using cotton swabs, bobby pins or twisted tissue can push wax against the eardrum ^[5].
• Over-cleaning. Too much cleaning can irritate the canal, cause infection and make impaction more likely ^[2].
• Hearing aids. The guideline tells clinicians to look in the ears of hearing aid users at health care visits ^[1], and a change in how a hearing aid works can be a sign of impacted wax ^[2].

Symptoms, and what isn't earwax

Impacted wax can cause ^[2][5]:

• Muffled or reduced hearing that gets worse over time
• A plugged or full feeling in the ear
• Ringing in the ear (tinnitus)
• Itching
• A change in how your hearing aid works

Red flags that need prompt care. The AAO-HNS Foundation says ear pain, drainage and bleeding are not symptoms of impacted earwax, and to seek care right away if you have them ^[2]. It also advises getting checked for hearing loss, ear fullness or pain if you're not sure earwax is the cause ^[2].

What you notice	Could it be earwax?	What to do
Gradually muffled hearing or a plugged feeling	Yes, often	Home care if you have no risk factors (see below), or see a clinician
Hearing aid seems weaker or works differently	Possibly [2]	Clean the device per its instructions; have your ears checked
Ear pain, drainage or bleeding	Not a typical earwax symptom [2]	Seek care right away
Hearing drops suddenly in one ear	Don't assume it's wax	Same-day medical visit; see sudden hearing loss

What not to do

Don't use cotton swabs or small objects. The AAO-HNS Foundation's advice is blunt: "DON'T put anything smaller than your elbow in your ear." Swabs, hairpins, car keys and toothpicks can cut the ear canal, puncture the eardrum or dislocate the hearing bones ^[2].

Don't use ear candles. The guideline recommends against ear candling for treating or preventing impaction ^[1]. The AAO-HNS Foundation says there's no evidence candles remove impacted wax, and they can seriously damage the ear canal and eardrum ^[2]. FDA goes further: it says there is "no validated scientific evidence" that ear candles work, considers them dangerous even when used as labeled because of a high risk of severe skin and hair burns and ear damage, and lets its import officers detain ear candle shipments without physical examination ^[4].

Don't over-clean. Excess cleaning can irritate the canal and actually make impaction more likely ^[2].

Don't treat wax that isn't bothering you. If you have no symptoms and your ears can be examined, the guideline says routine treatment isn't needed ^[1].

Safe home care, if it's right for you

Check first: should you self-treat at all? The guideline asks clinicians to look for factors that change how earwax should be managed ^[1]:

• Taking blood thinners (anticoagulants)
• A weakened immune system
• Diabetes
• Past radiation therapy to the head and neck
• A narrowed ear canal or bony growths in the canal
• A hole in the eardrum, or an eardrum that may not be intact

If any of these apply, or you've had surgery on your ear or ear canal, talk to a clinician before trying home treatment. The AAO-HNS Foundation notes that some medical and ear conditions make certain treatments unsafe ^[2].

If none apply, these are the accepted options:

Method	What it involves	Notes
Softening drops	Drops that soften wax; the guideline counts plain water or saline as options [1]	ENT Health lists mineral oil, baby oil, glycerin, and peroxide-based drops as home options [5]
Gentle irrigation (rinsing)	Water or saline warmed to body temperature, which helps prevent dizziness [5]	Using drops 15 to 30 minutes before can help [5]
Watchful waiting	Leaving it alone for a while	Impaction can resolve on its own [3]

Follow the product label for how to use drops. Don't irrigate if you might have a hole in your eardrum ^[5].

Know the side effects. A summary of the guideline lists possible side effects of drops as temporary hearing loss, discomfort, dizziness and skin irritation, and of irrigation as pain, skin injury and outer ear infection ^[3]. It also notes that no single method has been shown to be better than another ^[3].

Outside the canal: clean the outer ear with a soft cloth and don't insert anything ^[5].

When to see a clinician, and who removes earwax

See a clinician if:

• Home care doesn't help, or wax is blocking your hearing ^[5]
• You have any of the risk factors above
• You wear hearing aids or keep getting buildup. ENT Health suggests checkups every 6 to 12 months in those cases ^[5]
• You're thinking about over-the-counter hearing aids and have heavy earwax. FDA lists that as a reason to see a doctor first ^[6]

What happens in the office. Clinicians may use softening drops, irrigation or manual removal with instruments ^[1]. ENT specialists can remove wax under a microscope using suction or small tools, which is often preferred for people with diabetes, a weak immune system, eardrum tubes, narrow canals or skin problems in the canal ^[5].

The guideline asks clinicians to check the ear after treatment and confirm the impaction is gone. If symptoms continue after the wax is cleared, they should look for another cause ^[1]. If first attempts fail, the guideline says to refer to a clinician with specialized equipment and training ^[1].

Who to call. The guideline is written for any clinician likely to manage earwax, so your primary care office is a reasonable first call ^[1]. For wax that won't clear, it points to clinicians with specialized equipment and training ^[1], often an ENT ^[5]. Our guide to audiologists, ENTs and hearing aid specialists explains who does what.

Preventing buildup

The guideline tells clinicians to explain proper ear hygiene to people who tend to build up wax, and lets them counsel patients on control measures ^[1]. Options to limit buildup include softening drops and irrigation ^[3].

For most people, prevention is mostly about what you stop doing: no swabs in the canal, no candles and no over-cleaning ^[2]. Hearing aid users should have their ears looked at during visits ^[1].
