Earwax is naturally produced by the body to help protect, clean and lubricate the ear. Earwax is secreted by the glands in the skin lining the ear canal in order to prevent foreign particles from penetrating deep into the canal and damaging the eardrum.
With the assistance of chewing and regular motions of the jaw, small amounts of earwax are continuously transported from the ear canal to the opening of the ear. It then dries and is either washed away or falls out as new wax is secreted.
While earwax is usually extremely beneficial due to its lubricating and antibacterial properties, the buildup of an excessive amount can lead to blockage or impaction.
