Look after your teeth and gums.

An electric toothbrush takes the guesswork out of how to brush your teeth properly – you just guide it along the surfaces of your teeth and gums. We tried 7 models.

About our trial

Our user trial featured 7 electric toothbrushes.

Each toothbrush was used by 10 people. They were then asked how easy it was to use, how comfortable it was to grip and how effective it was at cleaning their teeth.

In the lab we assessed each toothbrush’s battery power and checked electrical safety. We also carried out a “shower test” to check whether the toothbrushes would work after being exposed to water. We turned off the toothbrushes, placed each one under the shower for 2 minutes, wiped it dry, and checked to see if still functioned. All the toothbrushes passed this test.

What to look for

Features to consider when you're choosing an electric toothbrush.

  • Most electric toothbrushes now come with rechargeable batteries plus a recharging unit.
  • A charge indicator alerts you when it’s time to recharge – useful when you’re travelling or if you regularly unplug your charger.
  • Different settings such as “daily use”, “sensitive”, “deep clean”, “whitening” and “massage” make for a more versatile toothbrush.
  • A timer helps you keep track of how long you brush each section of your mouth. Some brushes beep at intervals to tell you when to move on to the next section; others beep or switch off at the end of the pre-set cleaning time.
  • Families or couples who want to have their own brush heads and share the toothbrush handle will find a container/stand for extra heads useful.
  • A storage box/travel container is handy when you go away on a business trip or holiday.
  • Having a range of replaceable heads available means you can pick the one you prefer.

Teeth cleaning tips

Whether you use a manual or an electric toothbrush, these tips from the New Zealand Dental Association will help you look after your teeth and gums.

  • Brush twice daily. Make sure you clean all the surfaces (outer, inner and chewing surface) of your teeth and gums.
  • Use fluoride toothpaste and after brushing spit the toothpaste out. Avoid rinsing after brushing as this will wash the fluoride away from your teeth.
  • Floss or use interdental brushes once a day to clean between your teeth.
  • Avoid sugary, sticky or acidic foods and drinks between meals.
  • Eat a wide variety of nutritious foods.
  • Visit your dentist for regular check-ups.
