Dyson CameraJet      Price: €480Where To Buy: DysonAfter more years of brushing my teeth than I’d care to admit, I thought I had the technique down. Two minutes minimum, full mouth coverage, floss, rinse, teeth feeling sparkly clean afterwards. Full marks from the dentist at regular check-ups. I can’t take all of the credit; special mention has to go to the toothbrush, which has become increasingly fancy over the years. The most recent was an Oral B one that guided you through the process with an app and let you know if you missed a spot before the dentist got in there for a look. But I wasn’t prepared for the Dyson CameraJet. Yes, you read that correctly. Dyson has decided dental care is the next frontier, and it is bringing an AI-powered, camera-toting brush to the fight. And did I mention that not only does it brush, but it also flosses your teeth, too? The CameraJet uses a camera built into the toothbrush head to get a good look at your teeth, and with the help of machine learning, identify gaps between your teeth in real time. When it spots a gap, it fires off a jet of mouthwash – the “jet” part of the name – in the same way that you would use a water flosser, from a built-in tank that holds just enough for one brushing session. That eliminates the need for you to struggle with plastic picks or dental tape. In true Dyson fashion, it has changed things a little, opting for a conical jet of mouthwash to sweep everything away rather than a concentrated jet that might just pierce the plaque lurking on your teeth. The whole process takes three minutes if you have the automatic jet enabled; two minutes if you decide to go for a guided brushing session and manually control the mouthwash spray. It all sounds very simple, doesn’t it? The toothbrush tells you where to brush for how long and it will floss for you. Little did I know that I would need to relearn how to brush my teeth. It turns out years of using an electric toothbrush to do the work for me has meant I just assume that all battery toothbrushes will work the same. Not so. The Dyson brush requires you to move it in small oval motions, and getting the speed just right is tricky at first. [ Dyson PencilWash review: Powerful but pricey cleaner tackles hard floors with easeOpens in new window ]There are alerts. Brush too fast? The toothbrush bleeps. Overpressure? More beeping. Too little pressure? The same. The last two are opt-in, via the app, but the brushing speed is not, which is arguably the most frustrating thing about the brush.But that wasn’t the real learning curve. Learning how to brush my teeth while having high-velocity mouthwash fired at gaps was a bit of a challenge. The bathroom mirror took the brunt of it on more than one occasion, because when the autojet activates, it takes you by surprise. It was unsettling, even when I was expecting it. And you have to remember to spit a bit more regularly or risk dribbling like a toddler. It is hard to describe just how disconcerting the flossing feature is. It’s not the sensation that is the issue; it is the noise as it fires. It’s less of a spray and more of a shot. The first time it happened I jumped, and toothpaste went everywhere. In total, there were 83 jets fired at my teeth, which seemed a bit much. (That information came courtesy of the app, which tracks all your brushing sessions should you need that information.) Speaking of the app, it isn’t essential; all the controls you need are on the brush itself, from the autojet activation to the brushing intensity. But if you want a bit of extra information or help, the app’s guided brushing helps ensure you are covering all your teeth adequately, and also gives access to the live view. Because who doesn’t want to see their gums and teeth up close? The camera might give you privacy concerns. But Dyson says the camera doesn’t record images while you brush, and they aren’t transferred to the cloud. Once the brush is off, the camera isn’t active. Although Dyson recommends a low-foam toothpaste – all the better to see those tooth gaps with – the CameraJet will work with any toothpaste and mouthwash you prefer. You just might have to rinse off the camera more often. When you are done, you pop it on the dock to charge and refill the mouthwash at the touch of a button. The cost seems a little on the higher side, at €480. But that’s not even the most expensive toothbrush out there – Oral B’s iO 9 at full retail price will cost up to €600, although if you shop around you can usually find it on a half-price sale somewhere. I doubt you will see a cut-price offer for the Dyson any time soon. It is expensive but to put it in context, that’s around the same as four small to medium-sized fillings. And even with the autojet enabled, it is far less unpleasant than your dentist drilling a cavity or two. Regardless of how I felt about it at the start, I can’t argue with the results. A post-brushing check revealed that the Dyson left little or nothing behind. GoodThe CameraJet works. A quick floss after brushing showed nothing of note left behind. That is an improvement even on the fanciest toothbrush I owned, and I didn’t have to buy a separate water flosser to get there. The live view in the app is disconcerting and won’t be of interest to everyone, but it might help highlight any issues you have missed. A regular dental check-up, however, will also so the same. BadIt isn’t cheap, and replacement brush heads are unlikely to pop up in a cheap online deal.Until you get to grips with the technique, prepare to clean the bathroom mirror. A lot. And be prepared for the mouthwash jet. Everything elseYou refill the mouthwash through the docking station, which also doubles as the charger and mercifully has a USB C connection. The portable charger also has the same connection, and is far less bulky, so a better option for travelling. VerdictThe real proof will be in the next dentist visit, but all evidence points to the CameraJet doing what it promises. Does it clean my teeth better than a regular toothbrush and flossing? Honestly, yes, but that price tag will be a deal-breaker for some.
