You don’t want a button that is too easily activated or too firm, thankfully that is not the case on the 4000. It has a nice resistance when pressed. Not too soft that it can be accidentally activated, but not too firm it is difficult to press. Good even for those with limited dexterity in my opinion.
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. 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. If you are particularly interested in the feature set of the Smart 4 4000, the Oral-B Teenhas identical technical specs, but can be snapped up cheaper. The only differences are the design and box contents. 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.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… 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. It is important for your oral health to replace your toothbrush head every 3 months or sooner if your bristles are frayed. 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. As a result of this change, the Smart 4 and other models now have a battery life more fitting of the current climate.
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. 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 can find much more detail on each mode and how they compare in our article, Oral-B cleaning modes explained.If you didn’t know this or are guilty of not brushing for as long as you should, the Smart 4 can help in 2 ways. It takes a bit of practice to get in a routine of having your phone with you when brushing. If you forget it or don’t have it to hand, don’t worry. The handle will store the data for the last 20 cleans and sync this to the app, the next time it connects. I understand why though. If it did, there is no way of showing what mode it is on, unless you use the app. 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.
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. Go online, register the brush and you get a further 12 months absolutely free. That is 3 years of warranty.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. 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. With the Smart 4 4000, a 2 year/24 month warranty is included as standard from the time you buy the brush. 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. 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.
Electric toothbrushes that are clinically proven to be superior to manual toothbrushes, providing benefits in removing more plaque for cleaner teeth and healthier gums. Oral-B electric toothbrushes remove up to 100% more plaque than a regular manual brush, which is why they are recommended by UK dentists and hygienists. Oral-B electric rechargeable toothbrushes (from Pro 600 model upwards) also whiten teeth starting from day one by removing surface stains. Electric toothbrushes are suitable from ages 3+, with specific kids electric toothbrush models available, and are gentle on gums and suitable for sensitive teeth. Electric rechargeable toothbrushes come with replacement toothbrush heads, which should be replaced every three months. Now, this leads me to one of the biggest problems with the Oral-B Smart 4000 and that is the box contents. 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. 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. At times I have found these distracting, you may want to customise the settings to avoid some notifications.If you did not already know, this is generally the recommended brushing time. 2 minutes, twice a day. Does this Smart 4 have the ability to turn off the timer? If not, which brush should I be looking for? You should spend 30 seconds cleaning each section. The pacer helps you keep an even brushing time on these 4 sections. 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.
