Your ear canal produces a waxy oil called cerumen, which is more commonly known as earwax. This wax protects the ear from dust, foreign particles, and microorganisms. It also protects ear canal skin from irritation due to water. In normal circumstances, excess wax finds its way out of the canal and into the ear opening naturally and then is washed away.

When your glands make more earwax than is necessary, it may get hard and block the ear. When you clean your ears, you can accidentally push the wax deeper, causing a blockage. Wax buildup is a common reason for temporary hearing loss.

You should take great caution when trying to treat earwax buildup at home. If the problem persists, visit your doctor. Treatment is generally quick and painless, and hearing can be fully restored.
