“Electric toothbrushes make brushing easier as they do most of the work for you,” says Rosalind O’Leary, a dentist at Bupa Dental Care.

“Their rotating heads help make sure you clean more of your teeth’s surfaces and make it easier to reach tricky spots, like the back teeth.”

Among the most useful features, she says, are timers, which help you know how long to brush each area of your mouth, and pressure sensors, which let you know if you’re using too much force. “Brushing harder won’t remove more plaque and can actually be more harmful to your teeth and irritate your gums,” explains O’Leary.

Some toothbrushes connect to your phone, which can be useful for getting personalised advice on your brushing habits, and you may also want to look out for the word “sonic” which means the brushes vibrate at very high speeds and frequencies to buff the tooth surface and force toothpaste between your teeth.

But don’t be sucked in by these and other features and technologies unless you think they will be genuinely useful, O’Leary says. “The important thing is to choose a model that will effectively clean plaque, bacteria and debris from the teeth and gums, and is one you’re likely to use.”

Be sure to check how long the rechargeable batteries last (this can range from a week’s worth of brushing twice a day up to a year) and how often you’ll need to replace the brush heads, as well as how easily available and expensive they are.

Besides testing for the obvious (how clean our pearly whites felt and looked after cleaning) we also took into consideration value for money (including brush head replacement), battery life, cleaning modes, pressure sensor, plus any additional features including the smart app for the Bluetooth brushes.
