Oral-B - Smart 4 4500 Black Electric Toothbrush Powered by Braun - 1 Piece

Product Information

Buy the Genius 9000 and although you have to power the brush on to change the cleaning mode, if you have changed the mode, it will remember it. Next time you power the brush on, it will begin in that mode. The Oral-B Smart 4000 CrossAction electric toothbrush does not do this. 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. I suspect over time you will learn this, but wouldn’t some icons or LED’s be helpful to show the mode. The more premium Smart 6 and Genius range offer them. 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. 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…

With the Smart 4 4000, a 2 year/24 month warranty is included as standard from the time you buy the brush. You should spend 30 seconds cleaning each section. The pacer helps you keep an even brushing time on these 4 sections. Now, this leads me to one of the biggest problems with the Oral-B Smart 4000 and that is the box contents.Does this Smart 4 have the ability to turn off the timer? If not, which brush should I be looking for? Bluetooth connectivity allows the toothbrush to be connected to the Oral-B app allowing for a personalised brushing experience

The Oral-B Pro 2 2000 has 2 cleaning modes, the Pro 3 3000 has 3 cleaning modes, the Smart 5 5000 has 5 cleaning modes, so as you would imagine the Smart 4 has 3 cleaning modes….Yes, I know, I can’t quite figure that out either.If you feel you won’t use it, you may want to consider if the Pro 3 3000 is for you, you will be paying for a feature you won’t necessarily use otherwise.

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.There is the reality that most of us don’t need over a weeks battery life, but there is something to be said for having the ability to take a brush away on holiday and not having to worry about charging it! 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.

If you did not already know, this is generally the recommended brushing time. 2 minutes, twice a day. 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. I understand why though. If it did, there is no way of showing what mode it is on, unless you use the app. When using the Bluetooth connectivity, the app will show the cleaning mode. I will explain the connectivity option in more detail shortly.When you brush, sensors within the brush detect if you are applying too much force to your teeth. When it detects this, it activates the pressure sensor. A point to note here is the different versions of the Oral-B Smart 4 that I mentioned earlier. Whilst both models comes with the same cleaning modes, the Smart 4 4000S comes with the 2 x Sensitive brush heads, most fitting to the Sensitive cleaning mode offered on the brush.
