Meanwhile, the battery life is a little better than many of the other iO-Series brushes, with our test brush clocking 2 hours and 19 minutes of action before running flat so you can easily get through a month of brushing without a recharge. Even though I work in IT, I definitely don’t want to use my smartphone camera to track the position. The signature, round oscillating head is powered by five brushing modes and the brush still links up with Oral-B’s excellent app, which can give you insights into your brushing performance, as long as you put in the time with it.

The apps from Oral-B and Philips have had some time to mature, and they can guide you towards a better technique that could keep your teeth and gums healthier for longer. So, if you are travelling to Europe, Asia etc, the Series 6 cannot be recharged without a step down voltage converter.Otherwise, it has the same tech and the same key strengths as the iO Series 6 and iO Series 9, giving you a smoother brush with less vibration than the older Genius models, yet still delivering an excellent ‘fresh from the dentists’ clean.

Oral-B’s excellent app backs up the brush’s performance, so if you do have time and are interested in utilising all the tech to improve your technique, then you will be able to really fine-tune your brushing regime to get the most out of the brush and value for money. It looks sleek and stylish, is compact, has an optional self-cleaning case and an optional magnetic mount for storing it on your bathroom mirror. After all, we would all like squeaky clean teeth and a whiter smile – and absolutely no-one enjoys fillings or root canal surgery.Whether it was intentional or not, I do not know, but the 4 styles of iO specific heads are marginally bigger. Even more important than the type of brush you use is practicing good dental hygiene habits: brushing regularly and for the dentist-recommended two minutes, reaching all parts of the mouth, and flossing. These toothbrushes combine this with a pulsating action, designed to break up plaque along the gum line, making it easier to brush away. Round head electric toothbrushes oscillate thousands of times per minute, enough to efficiently remove plaque, bacteria and debris while brushing.
