Customer Ratings & Reviews

The Philips Sonicare 9900 Prestige has impressive cleaning performance paired with a real time feedback app to improve dental health far beyond what can be achieved with a manual brush.  In the box is the toothbrush, head, charging stand, USB charging cable, power adaptor, and charging travel case.  While not required for operation, in order to fully leverage the benefits of this toothbrush you will need to download the app. I had no issues downloading and running on my Android phone.  While you can brush without the app open, if you want real time feedback and history tracking you will need to open it when you brush. To pair to the app you need to put the brush on the base, open the app, and then turn on the toothbrush, at which point the app will begin tracking the two minute program and your brushing habits.  Within the app you can select multiple brushing options: three different intensity settings, and five different cleaning modes that range between 2:00 minutes to 3:20 minutes based on if your goal is sensitive, deep cleaning, gum health, whiten, or clean (default setting).    The SenseIq technology takes a bit of getting used to between the brush movement and the app response, but easy to navigate once you get used to the slight lag between where you are brushing and what the app shows.  The app breaks the mouth into 6 sections and then each section gets a 20 second interval.  Based on the toothbrush movement the app can identify which section of your mouth you have covered and then provides feedback if you brush too hard, move too fast, and adapts the intensity of the vibration based on the pressure you apply. The app will also let you know if you have missed an area and you can go back to that area to turn the section 'green', see photo for example of this feedback. The app also contains dental health tips, tracks brush head life and provides notification when to reorder. It leaves my teeth feeling extremely clean, as if I just came from the dentist's office.  If you battle with plaque build up, sensitive gums, or just tired of hearing your dentist tell you to brush better, this Sonicare will help you adjust your habits and get better cleaning results without spending the extra time on inefficient brushing. 

This product has worked great. Excellent travel case. Great for those that need feedback during their brushing to keep them on track. It also let's you know if your not brushing enough. My only complaint is that the app on the android phone does not always recognize when you start a brushing schedule. I have eventually figured out that if you sequentially start the app first and then grab the brush off the standing washer it works 95% of the time.

I love love love this product. It is a sleek version of older dated models and it is very much appreciated as it does what is promised. The negative? I detest to the moon and back having to connect online to temper its settings. I do not enjoy being held hostage to a third party operating this otherwise appreciated model.

Definitely an amazing clean. My old oral-b electric toothbrush died after many years. It was purchased from a dentist office and lasted 3 years. I was skeptical about the Philips Sonicare, but took a chance. The technology is different from the oral-b and I had to adjust to the technique. The clean is excellent and the guidance simple to follow. I will say I'm not a fan of using my phone to see details, but you can sync after you brush by connecting to the phone. The size is ideal for small hands and it is attractive for those of us who care. The carrying case is nice for travel and not overly huge. I do find it to be pricey, but if it lasts a couple of years like my prior oral-b then it is worth it.

Quite satisfied with the Prestige after two days of use. I was looking for a toothbrush that took up less counter space than my Diamond Clean, but was equivalent or better quality. It was quite easy to register the toothbrush from within the app. Changing settings from within the app is very easy. The beep telling you to move to the next quadrant could be louder and more noticeable. The brush head is fantastic. I keep the toothbrush on the charger. Works great. Have not used the case to charge the toothbrush yet. Very satisfied so far.

I've had a Philips Sonicare Diamondclean toothbrush for 5 years. Recently, the battery on that one started going out so I knew I needed a new toothbrush. I decided to purchase this one because the carrying case seemed much more convenient for travel. I was pleasantly surprised to find this brushed even better than my last toothbrush! It's hard to say if that's because the battery on my old toothbrush had weakened over time, but I've been pleased. I've removed a star because I do think it's pretty expensive for an electric toothbrush, particularly knowing that the battery life is likely equivalent to my last toothbrush (5 years) and repurchasing brushheads isn't cheap. I'm attempting to extend the life by not keeping it plugged in all of the time and only charging it when it is out of battery, though time will tell if this is effective at extending the battery life. That said, it really does clean exceptionally well, and the small footprint for storage is meaningful to me as I travel a lot.

Awesome toothbrush! Recommended by my dentist. It took some time to get used to but my teeth feel and look better than a regular tooth brush. I highly recommend! I ordered from Best Buy Mira Mesa. That's where i find all of my electronics. Thank You! Also, it's compact and convenient for travel. The battery lasts for a couple of weeks. Everyone should have this product. It has bluetooth and will tell you if you are brushing properly. You will have to download the app and set up your profile. Then you phone needs to be near you with the app open to talk to the wireless toothbrush.

After using my Phillips DiamondClean Smart for almost 5 years, I decided to replace it with the new model - the Sonicare 9900 Prestige. It didn’t disappoint me. I love it! Pros: - Very well made. - More compact design than the previous generation. - Travel case with the charging capabilities. - Improved brushing specs Cons: - Expensive Overall, I highly recommend if you are willing to spend extra money on a high quality product which might last you for a while.

Best toothbrush I’ve ever owned. Leaves your mouth feeling clean, fast charge and easy to connect to app to get all data. Worth the price

I use it everyday, love the look and feel of it and the charging stand is great. works great

Good, stylish, brush excelent. The only problem - it doesn't have any AI. Generally, Philips introduced unified head, stylish design and charging, 3 intensivity levels, sensor that alerts of scrubbing or high pressure and... that's it. App gives more tuning possibilities, but in fact, you do not it for daily use. And it doesn't actually perform any correct zoning and mapping how good you clean teeth. I was surprised by 6 buzz instead of usual 4. And then App showed that your mouth is 6 zones and you need to choose starting zone. So it register moves only when this zone is active. You can clean the whole month and it doesn't matter as in these specific moments only this area mattered. Also, travel kit doesn't allow to put the head with cover. Not hygienic in mi mind. By only at discounts of 250 and lower.

I bought this because my previous Sonicare Diamondclean of 10-11 years stopped working. This one is pretty expensive but worth it. I had this for about two weeks before I had another dentist appointment. The dental hygenist commented that my teeth were very clean and didn't say anything about flossing or gum recession (hint I didn't floss everyday, if my dentist is reading this I'm sorry lol). She probably spent about 15 minutes tops doing my routine cleaning. I owe this in part due to this toothbrush. With the accompanying app (if you don't want to use an app, just don't buy this, you won't get your money's worth), it guides you on how to brush your teeth, like if you scrub too much or if you have too much pressure. You can also set up zones where if you have sensitive gums or possible cavity prone areas it can focus more on those areas. At the end of the routine, it kind of grades you and tells you how to improve your brushing. I think if this toothbrush lasts a long time it will be well worth the high price and your teeth/gum health will be good too.

If you have problems with periodontal pockets or are just looking for a whiter smile this is the toothbrush for you. The app makes you pay attention to the areas your not brushing, but you feel the difference after 1 brushing. I feel like i just went to the dentist and got my teeth polished. 10/10 would recommend.

This is simply a first impressions review. The brush head will take some getting used to. It’s a little larger than the brush head on my old Sonicare. I also have a pretty small mouth. It’s definitely easier to get around my braces with the smaller brush head, but I will try to get this to work! The app is easy to use. It was easy to connect and it’s pretty neat with the feedback and tips it gives you when you’re done brushing. My teeth do feel cleaner compared to my old one. They feel smoother. I do wish you could make a profile where you maybe told the app/toothbrush you had braces or something similar. At least just so it knew. I didn’t find anything like this while playing around in the app. Overall it’s very nice. You are able to disable a lot of the features, although at this price point and just the point of the toothbrush in general, it wouldn’t really make sense to do that. If you aren’t into all the different features, then maybe go for a more simpler one. Otherwise it would be just a waste of money for you.

Best toothbrush I've ever used. Its expensive but my teeth feel cleaner than when I've tried the lower tier Sonicare models. I really like that it only has 1 button. The models with 2 buttons are confusing and hard to switch modes while brushing. I would like to see new colors. Maybe blue, green or red.

I’ve been a loyal user of the Philips Sonicare DiamondClean toothbrush for 10 years and absolutely loved it, so I was hesitant to upgrade. However, after switching to the Sonicare Prestige 9900, I can confidently say that this toothbrush has completely exceeded my expectations and transformed my daily oral care routine. The cleaning power is unmatched – my mouth has never felt this fresh and clean after brushing. It feels like a professional clean every time, leaving my teeth smooth and my gums healthy. The game-changer for me is the Bluetooth connectivity with the Sonicare app. It offers real-time feedback on my brushing technique, which I didn’t know I needed but now can’t live without. It guides me on pressure, coverage, and timing, helping me brush more effectively than ever. The app is user-friendly, and it’s amazing to see data on how well I’m taking care of my teeth. The design is sleek, just like the DiamondClean, but with even more smart features. If you’re looking for a top-tier toothbrush that will elevate your oral hygiene routine, the Sonicare Prestige 9900 is worth every penny!

I upgraded from the base Sonicare model that you can pick up for around $40. Even that was a massive improvement over standard brushing, but this toothbrush is a worthy upgrade if you want to take your brushing to the next level. The brush head does a good job with coverage while the 3 different power levels provide suitability for different people. It will even auto adjust the power level if you are brushing too hard. The carrying case is amazing & perfect for travel. I had a harder time transporting my older brush around due to lack of a case. Its also very durable; one drop was enough to take out the cheaper model, but I’ve dropped this a few times and it still works like day 1.

This toothbrush is by the best on the market...if you an serious about teeth and gum health...this is worth every penny..it even provides you with an app that ahows which areas of your teeth need more cleaning...this brush doesn't require scruubing, it does it all..you just gently move it around in secrions of 6 areas of you gums and teeth(it will remind you to move to different section with a beep).. I have tried many brushes and I think as humans we think we got all areas of our teeth clean, which majority of the time we even forget the gums...if you can afford this..you will not be disappointed.

For the longest time Philips Sonicare was considered the king of electric toothbrushes. After trying the 9900, I can safely say that they’re still the king. Let’s first talk about what’s included. You get the toothbrush head, the body, USB-A to USB-C cable, a AC charger, a charging stand, and a travel case. Everything looks and feels premium. Some of the features of the toothbrush itself are the three power settings, the pressure indicator on the base of the brush, the senseIQ, which itself was responsible for the adaptive intensity and scrubbing feedback. Now to the main part; how effective is it as a brush... From the moment that you turn it on, you hear the buzzing, you know that you’re in for a dentist feeling experience. As you brush, you get to see real time feedback on how hard you’re pressing as you brush. It actually helps you develop a better way of brushing. All in all it’s a great toothbrush, it has a premium build, great features, and I would definitely recommend it.

Excellent brush and super convenient. The charging puck is very secure and the carrying case definitely has a nice look to it that doesn't remind you of a cheap old toothbrush carrier or courtesy toiletries. 4 stars overall, though some improvements to the app would get the last star for sure. It's a little spotty on how it counts where you've brushed and it would be nice if there was a feature to easily go back over other areas as it only counts a given quadrant when it's its' turn. That being said, having 6 zones instead of 4 is nice. If you're like me, the app and convenience will definitely have you brushing more regularly right from the jump.
