About this deal

At times I have found these distracting, you may want to customise the settings to avoid some notifications. 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! 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. You see, applying too much pressure when brushing is a big issue and it causes more damage than you might think. Excessive pressure can damage the gums and cause wear on your teeth. A brush need only skim the surface of the tooth and gums. So, the brush reduces the power to protect your teeth.

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.

Now, this leads me to one of the biggest problems with the Oral-B Smart 4000 and that is the box contents. 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. 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.

As a result of this change, the Smart 4 and other models now have a battery life more fitting of the current climate. You should spend 30 seconds cleaning each section. The pacer helps you keep an even brushing time on these 4 sections.Another small but significant thing to remember is; put the brush in your mouth before powering on and changing modes otherwise the toothpaste might go flying across the room. You can find much more detail on each mode and how they compare in our article, Oral-B cleaning modes explained. I understand why though. If it did, there is no way of showing what mode it is on, unless you use the app. Various conditions may affect this quoted usage time, but safe to say you are getting at least double the performance, yet despite the battery change the physical size of the brush handle has not altered.

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. 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. The built-in pressure control technology senses your brushing technique and alerts you on your speed and pressure, helping protect your gums. The sleek toothbrush has three unique brushing modes that help to remove plaque, offer a superior clean and delicately whiten to achieve healthy pearly whites. Aside from the aforementioned 2 brush heads, the Smart 4 comes with a brush head stand included in the box. This is a moulded piece of plastic that clips around the charging stand that is also provided. The charging stand is fairly self explanatory, but I explain more about this in the battery section of the review.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. 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. 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. When using the Bluetooth connectivity, the app will show the cleaning mode. I will explain the connectivity option in more detail shortly.

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. Some Sonicare and Colgate models do actually achieve up to 3 weeks, but Oral-B are now much much closer in their capabilities. The idea behind this connectivity is to essentially be a little like having a dentist or hygienist looking over your shoulder saying good, bad, brush for longer, you missed a bit. It is about education for better cleaning rather than telling you that you have got it all wrong. Brushing for the full 2 minutes is very important, but just as important if not more so is the right technique. Make sure you learn how to clean your teeth properly. Up to 100% more plaque removal and gently whitens your teeth starting from day 1 by removing surface stainsIf 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… Sealed inside, these parts are protected from water and moisture. This means that the brush is water resistant and can be rinsed under a tap and used in a shower.
