Many people reach for a cotton swab after a shower without thinking twice. But putting a swab inside your ear canal can do more harm than good. At Hear SF on Geary Boulevard in San Francisco, owner and hearing aid dispenser Michael Martinez, NB-HIS, and our team often see how earwax and cotton swab habits affect hearing and hearing aid performance.
Earwax Has a Job
Earwax protects your ears. It traps dust and dirt, keeps the skin in the ear canal from drying out and helps guard against infection. For most people, the ears clean themselves. Jaw movement from talking and chewing slowly moves old wax toward the opening of the ear, where it falls out or can be wiped away.
Why Cotton Swabs Can Cause Problems
- They push wax deeper: Instead of removing wax, swabs often pack it further into the ear canal, where it can harden and block sound.
- They can injure the ear: The skin in the ear canal is thin, and a swab can scratch it or, in rare cases, damage the eardrum.
- They can lead to infection: Small scratches give bacteria a way in.
- They affect hearing aids: Packed wax can clog hearing aids and cause whistling or weak sound.
Signs of Earwax Buildup
- A plugged or full feeling in the ear
- Muffled hearing
- Itching or mild discomfort
- Ringing in the ear
- Hearing aids that whistle or sound weak
Safer Ways to Care for Your Ears
Clean only the outer ear with a washcloth. If you get buildup, over-the-counter softening drops may help, but check with your doctor first, especially if you have ear pain, a history of eardrum problems or ear surgery. Avoid ear candles and sharp objects. For stubborn buildup, a healthcare provider can remove wax safely.
