Earplugs are generally safe. However, they do come with a few potential side effects, especially if you use them regularly. Over time, earplugs can push earwax back into your ear, causing a buildup. This can cause several problems, including temporary hearing loss and tinnitus.

Can you get tinnitus from wearing earplugs?

Ear plugs cannot cause someone to develop tinnitus, although they can sometimes cause people to experience temporary tinnitus-like symptoms. Traditional noise-cancelling ear plugs are made from a pliable material that can be inserted in the outer ear lobe to help block out external sound.

Is it bad to wear earplugs every night?

Earplugs don't damage your hearing. You can use them every night provided you pay attention to hygiene—your hands should be washed and dried before inserting to prevent risk of outer ear infection. You should make sure that no earwax accumulates and that you don't suffer from an ear infection.
