The best electric toothbrushes

The Oral-B iO9 is your invite to the new era of brushing, truly giving you that dentist-clean feel every day. It looks great, reacts to you as soon as you pick it up and the interactive colour display is easy to use. Cycle through the seven different modes, including Daily Clean, Whiten, Sensitive, and connect to the app on your phone to get detailed analysis of your brushing technique. The new Frictionless Magnetic Drive distributes energy evenly to the tips of the bristles, making it a smooth experience. It's a powerful machine, but isn't too noisy. There's a Smart Pressure Sensor to tell you if you're brushing too hard, plus a timer on the brush and alert vibrations to ensure you brush for the right length of time. You'll get full charge in three hours from the small but sturdy magnetic charger - it's worth noting this is a two pin charger, so you may need an adapter. The charging carry case is a brilliant addition and it comes with one toothbrush head.

Despite the hefty price tag, the Philips Sonicare DiamondClean Smart Electric Toothbrush is described by reviewers as "exceptional" in build quality and attention to detail. The brush has impressive power but doesn't damage the gums and the Smart Sensor technology gives you personalised feedback to correct old habits and perfect your technique. You'll receive four heads with this product; plaque removal, gum health, whitening and a premium tongue brush. It has five modes to choose from and three intensities. If style is important to you, you'll really enjoy the unique charging glass and deluxe USB travel case, which give you 14-day battery life.

The ION-Sei is the only toothbrush to feature on our list that has a three-pin plug, which is great if you don't fancy buying a plug converter too. Plus, it comes with a handy EU plug for travelling. It arrives with two brush heads, standard and hard, but softer brush heads can be purchased separately. It has a smart timer and three brushing modes to suit your needs and the battery life is two weeks. What's really clever about this brush is its patented ion technology, which not only gets rid of plaque but deters it from coming back. It works with your body's natural electrical charge to attract bacteria on to the brush and away from your teeth. It's lightweight, looks great and the clear brush heads help you see if they've been cleaned properly, which is a great feature for the uber hygienic among you.

Want whiter teeth? The Philips Sonicare ProtectiveClean 6100 Electric Toothbrush promises just that, using its W Optimal White brush heads. Suitable for use with braces, fillings, crowns and veneers, it has a smart timer and comes with a travel case for ease. When it's time to change your brush heads, it will alert you, meaning you never have to worry about forgetting. It has three cleaning modes, three intensities and a pressure sensor, and the battery should last you two weeks.

If you want to learn more about your brushing and improve your technique, the Oral-B Genius 9000 CrossAction Electric Toothbrush will have you jumping for joy. It has all the usual features - six modes to choose from, a timer, comes with four round brush heads, a travel case and 14-day battery life, but that's not all. This nifty piece of kit connects to your smartphone via a Bluetooth app, and will tell you about areas you've missed, if you brushed too hard and more. It also has a ring which tells you if you're using too much pressure and it will reduce the speed accordingly.

If you want to feel like your dentist is in your bathroom, guiding your every brush, this one will definitely give you that sensation. Equipped with motion sensors and powered by AI, it learns about your brushing style and teaches you how to brush more efficiently. If you need encouragement to brush twice a day, the app also awards you with achievements to keep you motivated. As with many advanced Oral-B models, it has pressure detection technology and the battery lasts for more than two weeks. It has six cleaning modes and comes with a premium travel case.

The Philips Sonicare DiamondClean Electric Toothbrush has 14 days battery life, which is perfect if you regularly travel (or just don't want to charge it that often). It pulses water between teeth, breaks up plaque and promises exceptional cleaning. With five cleaning modes to choose from, it also comes with a clever travel charge case for on-the-go charging.

This toothbrush from Oral-B features just one mode, a round brush head, which allows it to contour to each tooth and it also features a built-in timer. What's more, it's compatible with a number of Oral-B heads to help you find your perfect combo. It has a super long battery life, so you should see seven days of use.
