Key takeaways:
- Earwax protects your ears from dirt, debris, germs and infections.
- Too much earwax buildup can harden and block your ear canal, causing pain and trouble hearing.
- There are a few ways to safely remove earwax buildup at home.
- But there are times you need to see your doctor instead.
Earwax might not be something you want to think about, but it’s totally normal. Knowing how to unclog your ears and get rid of earwax when you have a blockage may help you hear better and prevent ear infections, pain and more.
What is earwax, and why do we have it?
Earwax — the medical term is cerumen — is a waxy substance secreted by the tiny sebaceous and sweat glands that line the walls of your outer ear canal. It protects your eardrum from things like dirt and germs because it continuously regenerates.
“These secretions keep a flow going away from the eardrum toward the opening of the ear, catching dead skin cells, tiny hairs that line the ear canal and other types of microscopic debris along the way,” explains Mark Vaughan, M.D., a family physician and medical director at Auburn Medical Group in Auburn, California. When the earwax reaches the outside of your ear, it typically flakes off. Jaw movements, such as talking and chewing, help move things along.
Earwax also coats your ear canal, repelling water and preventing your skin from drying out. The wax is slightly acidic, so it “creates an unfriendly environment” for bacteria and fungus that tend to develop in the moist, dark environment of the inner ear, says Yu-Lan Mary Ying, M.D., an otolaryngologist and head and neck surgeon affiliated with Rutgers New Jersey Medical School in Newark. In fact, the earwax of people with diabetes is less acidic, making them more vulnerable to ear infections.
Why too much earwax can be a problem
“When ears are making the right amount of wax, it’s actually the sign of a healthy ear,” says Anh Nguyen-Huynh, M.D., an otolaryngologist and head and neck surgeon affiliated with the Cleveland Clinic. But some people make too much.
The American Academy of Otolaryngology says about 1 in 20 adults and more than one-third of seniors experience a buildup of earwax, leading to about 8 million earwax removal procedures each year.
“One factor has to do with the effects aging has on our glands — including the salivary glands in our mouth, the mucus glands in our nose and throat, and the glands in our ears — whose secretions can change in consistency,” says Isaac Namdar, M.D., associate professor of otolaryngology at Mount Sinai West Hospital in New York City.
