    You’ll be thoroughly impressed, even if you are upgrading from another electric toothbrush., September 11, 2017

    Verified Purchase(What’s this?)
    I recently upgraded to this toothbrush from a Philips Sonicare Flexcare and it has been absolutely worth it. If you are considering upgrading from a traditional toothbrush to an electric / sonic toothbrush I would recommend doing it immediately. For me, getting an electric toothbrush has been the best investments in personal hygiene by far. It is something I use multiple times a day, and every time I switch back to a traditional toothbrush or any reason, I can tell the difference. Even my dentist is astounded every time I go for a cleaning about twice a year, the sessions are super short as there is barely any plaque build up. If you are new to the space, I wouldn’t waste my time with other options and go straight the best money can buy, and fortunately you don’t have to look any longer because this product is it.

    Here are the biggest reasons why I’m loving it:
    – Good for travel / long battery life: I didn’t realize initially, but the battery has lasted me for over two weeks on a single charge! I just take this in the travel case and forget about charging it for a while.
    – Easy Charging: Unlike my Sonicare Flexcare, you don’t have to place the toothbrush on-top of a charging pin, you can simply place it in the charging cup. The cup can also be easily cleaned which is a big plus. You want this process to be as easy as possible and this delivers the best experience I could have ever imagined.
    – Seamless / waterproof / handsome design: Over time, my old Fexcare toothbrush started smelling funky because water and gunk accumulated around the seams between the rubber at the bottom charging area. I can already tell this will not happen with this toothbrush because of it’s unibody and seamless design. I’d also like to mention the toothbrush and charging cup look really great, I’m proud to have guests go into my bathroom and admire this gadget. I’m trying to convince my wife to get the same toothbrush in pink, not only because it’s a great product, but it will make our bathroom look even better.
    – Useful Smartphone App: I honestly thought the app would be gimmicky, but I was completely wrong. I build software products for a living and I can tell Philips has invested significant resources into building a truly useful mobile app. It blows my mind how well the accelerometers and pressure sensors work and the useful information that it relays to improve your brushing form and tell you where you missed a spot. Brushing too hard is a real issue with electric toothbrushes since in extreme cases, it could wear your gums down, this toothbrush tells you if you are doing it too hard so you don’t have to worry! You don’t need to use the app for this though, the toothbrush has a light at the bottom that tells you if you are applying too much pressure.
    – Overall very well thought-out user experience: From the unboxing to the first use, I was delighted at every corner. One of the best consumer electronic experiences I’ve had.

    I hope that helps!

    Comparing this to the previous model. Is it worth upgrading?, September 4, 2017

    I’ll be comparing this to the Philips Sonicare Diamond Clean Rechargeable Toothbrush w/Deep Clean Mode with Adaptive Clean Brush Head, Black which is an earlier model that I’ve used for the past two years (pink is the new one, black is the earlier model).

    If you haven’t tried a sonic toothbrush before you will be amazed at how clean your teeth feel. Using a sonic brush rivals any cleaning I’ve ever gotten at a dentist office. I won’t ever go back. That being said, there is some sticker shock with most sonic brushes. My previous Sonicare Diamond Clean brush was $139 which felt obscene until I tried it. This new brush is over $100 more. Is it really worth it?

    No. Probably not. If you already own a Diamond Clean brush, the upgrades here are not worth the price hike in my opinion. This brush is a little smoother–if that’s the way to describe the sonic pulsing action–but not in a massively noticeable way. You get an extra brush head, a tongue cleaning head to go along with the new tongue cleaning mode, and the brush can automatically detect the type of head you are using and use the corresponding brush mode. Oh and you can track your brushing in an app. Cool stuff, sure, but $100+ worth of cool stuff? Not for me.

    I do really love this line though–hence the 4-star rating– and if you want the extra features this brush provides, you won’t be disappointed. I love mine, but if you don’t want to spend the money, you can get a similar result from less expensive models

    “Bluetooth Toothbrush?” Yep, June 15, 2017

    Joanna D. (USA) –

    This is a pretty pricey toothbrush “system” but my dentist, who is up on all the latest tech, is a huge fan of Sonicare and he tracks how well you do when you change dental care appliances. So I had bought the older version of this toothbrush on his recommendation (he had a very good deal) and also a Waterpik WP100W Ultra Dental Water Flosser . So you can easily spend two to four benjamins for home dental care and not bat an eye. This newest version has an Android or iOS app and (irony of ironies) BLUETOOTH. Why? So it can keep track of your dental hygiene and coach you and remind you on your phone. This is kind of a gimmick but it could be enough to encourage you to better dental care.

    I also bought an UltraFlosser (scouting sales) and now I have the DiamondClean, which adds interactive coaching. I admit to skiving off two minute brushing now and then for a swish and a promise. I think the app and coach will be useful to encourage me to be diligent. It also asks did you floss? Ok. You can see if you did nor not and how often.

    Cool app. Choose a goal (whitening, gum health, breath (tongue scraping), interdental. Different heads for the brush accomplish this with coaching from the app.

    Interactive phone screens show you when to change quadrants and how long to brush and record your progress and daily discipline. If you use the wrong motion, the head sends a message to the app “use less motion.”


    App–didn’t detect one quadrant (was brush not close enough to phone?) I got three out of four and it didn’t find my lower right (end quadrant.) Takes some fidgeting to get this right.

    The CHARGER. Oh. My. Goodness. Shoot over-designing engineers, someone. The charger is a dished-in induction base that a glass (that’s right, a drinking glass) sits on. You prop the brush into the glass. So, if there is water in the glass, then what? If the glass breaks? Eh. Guys, guys, did you think this through? Need a replacement glass? Now what (esp. if the model is discontinued.)

    You do get a travel charging case with a port in the bottom behind a door with a USB cable. So you CAN USB charge this brush. So don’t lose that case or break it.

    The Brush Heads. They have a RFID transmitter or something in each head. So you need the speshul heads to interact with the phone app. So your local pharmacy, will they carry these (even behind the locked case?) In our rural town? Probably not. So you will have to keep the proper model number on hand and order online. Philips Sonicare Premium White replacement toothbrush heads, HX9062/95, Smart recognition, Black 2-pk These are the ones, more expensive and NOT (yet) on Subscribe & Save. Fifteen smackers a head. And they wear out in how fast? Four months or less? Great (for Philips.) And it’s THESE heads, not the similar-looking ones that lack the little transmitter (look for the round icon on the base of the brush that shows the smart transmission function.)


    Yes. If you need coaching to make sure you do your dental hygiene, especially if you have periodontal issues. The phone app is fun. I’ve been using a Philips Sonicare for a while, Definitely, it takes far less time in the dental chair to descale my teeth and there is less tartar on my trouble spots. The hygienist says she really can tell when I’m using the better toothbrush–so now I carry it with me on vacations. Can’t be without it. However, it’s not enough just to use the toothbrush.

    When I went back for my check-up and cleaning, my dentist was delighted. “Oooh, look, you have STIPPLING!” What, pray tell, is stippling? He pulled out a hand mirror, pulled back my lip and showed me my upper gum. “See those white hard areas on top of the pink tissue? That’s healthy gum. If your gums are bad, they are darker pink and mushy. Healthy gums are hard and lighter in color and have that mottled look when they are really good.” Ok. And they map the periodontal pockets with a probe that has a millimeter scale on it. 1 or 2 is good. 4 or 5 means some gum has detached from the tooth, and severe periodontal disease as having at least two teeth with measurements of 6 mm with an adjacent tooth of 5mm. Severe periodontal disease puts you at risk of tooth loss and heart disease is associated as well (the bacteria in the pockets can land on heart valves. I have this info directly from a professor at U. Penn Dental School with whom I had some dealings when I was working in a scientific field some years ago.)

    You want to eliminate those deep pockets, so brushing with…
