You can find much more detail on each mode and how they compare in our article, Oral-B cleaning modes explained. It need not be a suction cup holder like the Genius 9000 comes with, but a countertop option would be a nice alternative. It would only cost a few dollars extra. 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.

Prices are always subject of course and what value you place on the brush might be different to me. 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. With regards to the Smart 4000 specifically; it has a few more extras in the box, which some might not use and find unnecessary. The brush head holder is only any use if you use multiple heads or share the handle with others. The different head styles might too be surplus to requirement, if you have a preferred style. When using the Bluetooth connectivity, the app will show the cleaning mode. I will explain the connectivity option in more detail shortly. Does this Smart 4 have the ability to turn off the timer? If not, which brush should I be looking for?Aside from the aforementioned 3 brush heads, the Smart 4 comes with a brush head storage compartment included in the box.

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. 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.

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. 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. With the Pro 3, there are a series of dimples running from the top to the bottom of the handle. These dimples are far more subtle in appearance. They do provide texture onto which the fingertips can grip, but they are not quite as effective as the raised ridges on the 4000.

Sadly with this Oral-B smart toothbrush, you will need to hold the smartphone or come up with your own mounting solution in the bathroom. At times I have found these distracting, you may want to customise the settings to avoid some notifications. 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. Enhance your smile with the Oral-B Smart 4 - 4000N Rechargeable Electric Toothbrush in White. 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.

Brush for the right amount of time

In our testing, we were able to get 66 minutes of usage time from the rush, which equates to 16 days use. 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 electric toothbrush does not do this. What I find somewhat odd is that Oral-B have not included a Gum Care or Sensitive brush head with the 4000. Would that not make sense to pair with the sensitive cleaning mode?!

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. Up to 100% more plaque removal and gently whitens your teeth starting from day 1 by removing surface stains It has not been designed to be easily repaired by yourself. Trying to replace parts like the battery will likely break the brush. This makes it more likely to be discarded rather than repaired if broken. Prices will vary from store to store. Quite often online retailers will have the best price, but promotions run by high street stores at certain times of the year will see them come inline or cheaper than other retailers.With the Smart 4 4000, a 2 year/24 month warranty is included as standard from the time you buy the brush. 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. If you look at the technical specifications of these 2 brushes, there isn’t a great deal between them. 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!
