It is not recommended to pull out earwax by yourself to avoid damaging the ear canal and causing infection, which can be handled by a professional doctor.
Usually, if there is not a lot of earwax left in the external ear canal, it can be dislodged by itself when chewing or exercising, and there is no need to pull out the earwax by oneself, so as to avoid damaging the ear canal and causing infections, which may lead to otitis externa.
If too much earwax accumulates in the ear canal, it is recommended to go to an ENT department and have a professional doctor operate under the otoscope to remove the earwax with tweezers. If the earwax is hard and blocking the ear canal, 5% sodium bicarbonate solution can be put into the ear to soak and soften the cerumen, which should be rinsed out with warm saline or sucked out with a suction device.
It is not recommended to pull out earwax by oneself for small ear canals. It is recommended to seek medical advice and have the earwax cleaned by a doctor on a regular basis.
