Most people’s ears clean themselves and it is not necessary to have them cleaned professionally.
For people who experience a build-up of ear wax there is not fixed time period to have it removed. As a general rule ear wax should only be cleaned if you are experiencing problems and difficulties with it. Otherwise it should be left alone.
Annual ear examination appointments with your local Audiologist or Hearing Aid Dispenser are recommended to ensure your ears are in good health. This is similar to visiting an optician to have your eyes checked or a dentist to have your teeth inspected every year.
