Ear irrigation is a good method for removing a buildup of cerumen, commonly known as earwax. When done by a trained professional, ear irrigation is safe and painless.
Some people secrete more ear wax than others, or their ear wax is dry and tends to cake. Consequently these individuals may develop issues with earwax buildup, which can impede hearing; excess wax can even press on and damage the delicate eardrum.
In some individuals, the high volume of earwax is just a natural thing without an apparent cause. For some, wearing a device that blocks the flow of wax from the ear canal can cause buildup, so individuals who wear a hearing aid or who use ear plugs for sound deadening are particularly susceptible to problems of this nature. Sometimes people who spend a lot of time on the telephone can develop earwax buildup on one side.
