Earwax plays an important role in protecting the ear canal from dust, debris, and bacteria. However, when earwax builds up excessively or becomes impacted, it can block sound from reaching the eardrum and lead to temporary hearing loss. Common symptoms include muffled hearing, ear fullness, ringing in the ears, discomfort, dizziness, and occasional ear pain. Understanding the causes of earwax blockage and knowing when to seek professional care can help prevent complications. Learn how impacted earwax affects hearing, the warning signs to watch for, safe removal methods, and why avoiding cotton swabs is essential for maintaining healthy ears and clear hearing.
