Clients often ask me, why do their ears seem to produce more earwax since wearing hearing aids? Hearing aids can stimulate the ear canal gland and cause it to produce more earwax than normal. This is why so many people report an increase of earwax when they begin using hearing aids: it’s how the body naturally reacts to something foreign in the ear. Up to 50% of hearing aid repairs are due to ear wax. Ear cleaning should also be a part of your hearing aid maintenance routine.
