Because it logs your brushing sessions, it holds you accountable a bit more as you can see when you have, or perhaps have not brushed.
A little extra that the Smart 4 comes with is a brush head stand. This is a white plastic module that clips around the charging stand with 2 prongs on, onto which brush heads can be placed. If you activate it often, don’t worry all that much, over time you will learn and avoid doing lasting damage to your teeth. Just imagine if you didn’t have it… It is a little harsher/aggressive feeling than a Sonicare or Colgate brush. Whilst this is not exactly the best way of rating a clean of the teeth, it really feels like it has done something. You should spend 30 seconds cleaning each section. The pacer helps you keep an even brushing time on these 4 sections.At the same time as the LED pressure sensor illuminates, you should also notice that the speed of the brush head will decrease and the sound of the motor will change. This is nothing to worry about. It is programmed to do this, until such time as the pressure is relieved. If you look at the technical specifications of these 2 brushes, there isn’t a great deal between them.
The heads are interchangeable, so you can select your preferred head and use it with any of the cleaning modes, although some work best with particular modes. Right at the top of the brush handle is a metal prong, this is what the brush head connects to and feeds the power from the brush motor. I understand why though. If it did, there is no way of showing what mode it is on, unless you use the app. 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. As good as the app is, I feel this may also be one of the negatives as some will not see the point of using it or find it more hassle than it’s worth. You don’t have to if you don’t want to.If you take a look at the very bottom of the brush handle, there is a recess, into which the pin on the charging stand connects to. A charging stand is provided. As a result of this change, the Smart 4 and other models now have a battery life more fitting of the current climate. 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.

This ultra-smart electric toothbrush gives you professional guidance on getting the most out of your brushing experience. This ingenious tool connects seamlessly with the Oral-B app on your phone, to help you achieve better cleaning results. Technically the Pro 3 is the best value, but the Smart 4 really isn’t much more expensive if you think you will benefit from the Bluetooth.
Two plus weeks of brushing with one chargé
At 30 second intervals, the brush will provide an audible warning via a slight pause in the brush motor at to tell you to change quadrant. Once the 2 minutes are up 3 brief pauses in the brush motor will be heard and felt. 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.
