Most hearing aid repairs are caused by ear wax plugging the sound tube opening. Other cause are dropping it and pets chewing the hearing aid, but most often they chew the ear mold/tip, attracted by the smell and taste of ear wax. Keeping your hearing aid, ear mold/ tip/ dome clean removes the pet chewing attraction.
Ear wax is warm, moist, and acidic that forms in our ear canal. It’s purpose is to keep dirt and bugs from getting down in our ears.
If your ear drum is normal and non-perforated, you can flush your ears regularly with an ear wax removal kit, or diluted hydrogen peroxide, or warm water.
Always check with your doctor before doing any type of earwax removal, and do not put anything in your ear if you’ve had surgery, an infection or any other complications of the ear.
