Does wax in the ear cause permanent or temporary deafness?

Earwax does not cause permanent or temporary deafness. Earwax, also known as cerumen, is a naturally produced substance in the ear canal that protects the ear from damage and infection. However, excessive earwax can cause temporary hearing loss or discomfort. This can occur when earwax builds up and blocks the ear canal, preventing sound waves from reaching the eardrum. In these cases, removing the excess earwax can restore normal hearing.
