If something is inserted far enough into the ear canal, it can cause damage including hearing loss. Fortunately, most of the time, this is not the case. Usually young children and those with intellectual disabilities are the primary patients for this health problem. If the object remains in the ear longer than one day, you should see your doctor. If the object is particularly dangerous, such as a battery, see your doctor right away.
