Despite the criticisms of the way in which the cleaning modes are presented, I do love the clean that an Oral-B brush offers. Studies have suggested Oral-B’s oscillating and rotating technology is superior, but there are studies that side with Sonicare. You can bring the cost down further if you were to share it with other members of your household. All you need do is invest in extra brush heads.
To fit or remove the brush head simply align the metal with the hole in the shaft of the brush head and push the two together until you hear and feel them clip into place. Go online, register the brush and you get a further 12 months absolutely free. That is 3 years of warranty. With the Smart 4 4000, a 2 year/24 month warranty is included as standard from the time you buy the brush. One of the benefits with the Smart 4 is that you do get 2 of the same brush heads included, so if you like that style of brush head you do save yourself a little on the cost.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. 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. 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 can find much more detail on each mode and how they compare in our article, Oral-B cleaning modes explained.
For 99.9% of users there will be years of hassle free brushing, but should you be one of the 0.01% where inevitably something does go wrong, Oral-B do not leave you high and dry. Does this Smart 4 have the ability to turn off the timer? If not, which brush should I be looking for? 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. 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 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.If you did not already know, this is generally the recommended brushing time. 2 minutes, twice a day. 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. 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…
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. 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. It is important for your oral health to replace your toothbrush head every 3 months or sooner if your bristles are frayed.As a result of this change, the Smart 4 and other models now have a battery life more fitting of the current climate. The charging stand is fairly self explanatory, but I explain more about this in the battery section of the review. 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. 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.
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. This means that the LED sat behind the panel lights up. You get a bright red light that you won’t fail to notice. 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. The very nature of being an electronic item with moving parts does indeed make the brush susceptible to failure. However, the reliability of Oral-B products tend to be very good. Up to 100% more plaque removal and gently whitens your teeth starting from day 1 by removing surface stainsIn our testing, we were able to get 66 minutes of usage time from the rush, which equates to 16 days use. There are 2 parts to the brush, the handle I have been describing. This has all the clever bits of technology in.
Great Deal
