Can be useful for

A product can support daily care but can’t treat a dental problem on its own. See a dentist if symptoms persist.

Choosing electric toothbrushes

  • Prioritise a pressure sensor and a two-minute timer with 30-second prompts.
  • Check the cost and availability of replacement heads – you'll need a new one every three months.
  • Choose soft brush heads, especially if you have sensitive teeth or gums.
  • Extra modes, apps and cases are optional – a basic daily clean mode is enough for most people.
  • If you wear braces or have implants, ask your dental team which brush head they recommend.
