Pros / It has built-in pressure and scrubbing sensors, and it comes with an intuitive app for personalized coaching and tracking.
Cons / It’s the most expensive electric toothbrush we tested, and its Deep Clean+ mode may feel too intense, especially if you have sensitive teeth.
Verdict / The Philips Sonicare DiamondClean Smart is a premium electric toothbrush that comes at a premium price. High-tech and refined, it includes Bluetooth capability and personalized coaching to help you meet your oral health goals.
If you’re someone who looks for the top of the line, the Philips Sonicare DiamondClean Smart delivers. Because its downloadable app has so many coaching and tracking features, Philips Sonicare markets this toothbrush as a “complete oral care solution.”
The toothbrush handle has a slim, ergonomic design with sophisticated LED lighting. As it interacts with its high-tech, microchipped brush heads, the handle automatically adjusts its mode and intensity to the corresponding settings. The toothbrush also tracks your brush head usage and prompts you when it’s time for replacements. You can order them right through the app.
Like Oral-B’s leading toothbrush, the Oral-B Genius Pro 8000, the Sonicare DiamondClean Smart comes with a smart travel case so you can charge your toothbrush and phone simultaneously. When you’re not on the road, you simply place the handle in its charging glass to keep its lithium-ion battery powered, and the charging glass doubles as a rinsing glass. A full charge gives you 14 days of operating time, and the toothbrush’s battery indicator light flashes white until the handle is ready. Although one of our testers thought the charging glass might be hard to keep clean, its overall look is impressive.
“It just looks cool,” said the manager of our lab, “and that ain’t easy for a toothbrush to do.”
When we compared Sonicare’s app with Oral-B’s, we found Sonicare’s to be more intuitive. We liked the DiamondClean app’s interactive TouchUp feature, and we found its Smart Location Sensor more useful than Oral-B’s Position Detection. We also liked the DiamondClean’s BrushPacer. It helps you track your brushing through six zones in your mouth, and the toothbrush’s accompanying pressure sensor helps you maintain proper technique. If you press too hard or use a potentially damaging scrubbing motion, a light ring on the end of the handle flashes, and the handle itself vibrates, creating a multisensory reminder to brush gently.
To assist you further, the DiamondClean Smart comes with three brush heads and a tongue brush. Its Plaque Control brush head has soft, flexible sides that contour to the shape of your teeth, and its Gum Care brush head is designed to reduce inflammation. The Premium White brush head works on tough stains, and the TongueCare+ cleaning head helps freshen your breath. With four cleaning modes and three brushing intensities, the DiamondClean Smart has more setting than even the Philips Sonicare FlexCare Platinum Connected to help personalize your brushing experience.
Before we tried brushing with this toothbrush, our initial reaction to its price was, “No way!” Once we held it and used it, however, we admit being tempted to splurge. We thought the toothbrush handle felt smooth and sleek, and everything about it seemed classy. We were also impressed with its cleaning power. If a $200+ price tag doesn’t scare you, the DiamondClean Smart is a smart choice, and you can buy it in black, pink, white, gray and lunar blue.
