Earwax / cerumen impaction — general information

Earwax (cerumen) is a natural mixture of oils and shed skin that protects the ear. When it accumulates or hardens it can form an impaction (buildup) that affects hearing and comfort. This page summarizes causes, typical symptoms, safe precautions, and when to seek professional evaluation.

What earwax is and how impaction forms

Earwax is produced in the outer ear canal and normally moves out on its own. Factors such as narrow ear canals, increased production, or reduced clearance can allow wax to build up and harden into an impaction. Individual anatomy, age and repeated interference with the ear canal influence accumulation.

Common causes and risk factors

Factors that make impaction more likely include inserting cotton swabs or other objects into the ear, frequent headphone or earplug use, swimming in dirty water, certain skin conditions, and older age. Some people naturally produce thicker wax or have ear anatomy that prevents normal clearance.

Symptoms and when to seek care

Impaction may cause reduced hearing, ear fullness, tinnitus (ringing), occasional discomfort, and sometimes balance changes. Seek prompt professional assessment if you have severe or worsening pain, fever, bleeding, facial weakness, sudden major hearing loss, or signs of infection—these may require urgent evaluation.

Safe care and what to avoid at home

Avoid inserting cotton swabs, hairpins or other objects into the ear canal. These can push wax deeper, injure the skin or perforate the eardrum. Routine gentle external cleaning of the outer ear with a damp cloth is safe. If symptoms persist, a clinician can inspect the ear and perform safe removal methods when needed.

Clinical approaches and referral

A trained clinician or ENT specialist will examine the ear with an otoscope and choose an appropriate removal method—such as irrigation, suction, or manual removal—based on the impaction and ear health. Recurrent buildup may prompt evaluation for underlying causes and preventive advice.
