What can cause an earwax build-up?

Some people regularly get blocked ears because they naturally produce a lot of earwax.

Other factors that can increase the risk of too much earwax include:

  • producing naturally hard or dry earwax
  • having narrow or hairy ear canals (the tube between the opening of the ear and the eardrum)
  • being elderly, as earwax becomes drier with age
  • bony growths in the outer part of the ear canal

Earwax can also block your ear if you frequently insert objects into your ear canal, such as cotton buds, ear plugs or hearing aids .
