Problems begin when wax builds up faster than the canal can shed it. This condition, known as ear wax blockage or impaction, can cause muffled hearing and discomfort. It is more common in people who wear hearing aids or earphones daily, those with narrow ear canals, and individuals who attempt cleaning with cotton buds — which often push wax deeper instead of removing it.

Moreover, ear wax buildup is not always the result of poor hygiene. Instead, it often develops due to natural factors such as canal shape, device use, or skin conditions. Consequently, even individuals who clean their ears regularly may still experience blockage. Therefore, understanding these underlying causes helps patients seek timely ENT care.
