Key takeaways:
- Earwax protects your ears from dirt, debris, germs and infections.
- Too much earwax buildup can harden and block your ear canal.
- There are a few ways to safely remove earwax buildup at home.
- Sometimes it’s best to have a medical professional remove earwax.
Earwax might not be something you want to think about, but having it is totally normal — as is having it build up, which is also known as impaction. Knowing how to unclog your ear canals and get rid of excess earwax when you have a blockage may help you hear better and prevent ear canal inflammation and infections, pain and more.
What is earwax, and why do we have it?
Earwax — the medical term is “cerumen” — is a 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.
“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 Dr. Mark Vaughan, 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.

Why too much earwax can be a problem
While a little excess earwax is merely an annoyance, too much can create a blockage. That buildup is tough to remove, especially if it’s hard and dry. It can cause difficulty hearing, a stopped-up or full feeling in the ear and pain. 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 ear canal, says Dr. Yu-Lan Mary Ying, an otolaryngologist at University Hospital in Newark, New Jersey. In fact, the earwax of people with diabetes is less acidic, making them more vulnerable to ear canal infections.
The American Academy of Otolaryngology says about 1 in 20 adults and more than one-third of older people experience a buildup of earwax, leading to about 8 million earwax removal procedures each year.
