This price does exclude the cost of water, toothpaste and electric to charge it. This price also works on some assumptions, but you get a rough idea. In the unlikely event, something goes wrong, there is as standard a 24 month warranty is provided with the 4000. This covers the battery too. Register the brush online and you get an extra 12 months at no extra cost, so 36 months or 3 years in total. Oral-B iO™ with revolutionary iO™ technology is the latest Oral-B electric toothbrush. After six years of research and over 250 patents, Oral-B iO™ sets the new standard of brushing performance, experience, and design. Experience a deep but uniquely gentle clean with a new frictionless magnetic drive. It directs all energy to the bristles to generate new micro-vibrations. The result is Oral-B’s best ever clean: 6x more effective plaque removal along the gumline for 100% healthier gums in one week.** Ideally, a way of selecting the mode prior to actually turning the brush on would be the solution. This is not available, not even on the premium Genius 9000 model.

I understand why though. If it did, there is no way of showing what mode it is on, unless you use the app. If you did not already know, this is generally the recommended brushing time. 2 minutes, twice a day.Up to 100% more plaque removal and gently whitens your teeth starting from day 1 by removing surface stains At times I have found these distracting, you may want to customise the settings to avoid some notifications. You should spend 30 seconds cleaning each section. The pacer helps you keep an even brushing time on these 4 sections. The main feature of the app is the on screen timer and guide that shows you where to brush and how well you have brushed.

Each of the 3 cleaning modes work slightly differently, with differing levels of oscillations, rotations and pulsations to achieve different cleaning effects on the teeth. If you are going to offer smart features you need to encourage use and a smartphone stand would have been helpful in this case, to give the phone a home rather than the user having to hold it or place it on a work surface.

I think this is a big oversight and even if it meant a few extra pounds being added to the price, I think it would have been a worthwhile addition. While you are improving your brushing routine, Oral-B's unique round head does all the rest. It removes up to 100% more plaque than a standard manual toothbrush for healthier gums and it starts making your smile whiter as of the first day of brushing by removing surface stains. Not only this, but the toothbrush helps you protect your delicate gums with the proprietary pressure control technology that reduces brushing speed and alerts you to be gentler if you brush too hard. The likelihood is that it would survive, but I strongly advise you avoid submerging the brush below water, for example in a bath or sink. A rinse is fine, but the brush does not need to sink to the bottom of a bowl of water. Official Oral-B brush heads are recommended and they all have something known as indicator bristles. These are Blue coloured bristles that will over a 3 month period gradually discolour. Some Sonicare and Colgate models do actually achieve up to 3 weeks, but Oral-B are now much much closer in their capabilities.
