Earwax (cerumen) occurs naturally and serves to protect, cleanse, and lubricate the ear canal. For some, earwax will naturally work its way out of the ear but for others it may build up and become impacted. This can create a temporary hearing loss or feeling of fullness in the ears. Use of cotton swabs to remove earwax is not recommended as it can make the buildup worse by pushing the earwax deeper into the ear canal. Your audiologist can safely remove earwax. He or she may also recommend the use of mineral oil or other softeners to help prevent future buildups.
