Impacted earwax happens when you have too much of it. When it starts to partially or completely block your ear canal, it is considered impacted.
Objects placed in your ear can also lead to a blockage, especially if done repeatedly.
Having impacted earwax can cause a number of symptoms and issues with your ears and hearing. It can also prevent a full exam of the ear. If you have too much ear wax at the time of your hearing test you may be asked to visit your doctor if the clinic doesn't perform the earwax removal service.
Most people have a small amount of earwax that regularly makes its way to the opening of the ear. If you have excessive earwax, it may build up and block your ear canal. Earwax can get pushed deep within the ear canal if you use a cotton swab.
You're also more likely to have wax buildup if you frequently use earphones. They can inadvertently prevent ear wax from coming out of the ear canals and cause blockages.
