Customer Ratings & Reviews

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.

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

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.

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!

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.

Replaced a 5-year-old Sonicare. I'd recommend this product over any item I own. Zero cavities and better teeth since I started using one

Great toothbrush, but the app needs help, and the "brush head life is too short for the price you pay for replacement brush heads. The toothbrush itself works amazing. My teeth feel clean and instead of brushing in quadrants, it has you brushing in sixths. I actually like this! So from a basic performance aspect, this brush is amazing! But.......the app is very inconsistent. I will be brushing the back of my teeth and the app does not seem to realize this. Then, after I finish brushing, it wants me to go back over the areas that I missed, but I already brushed them. To spend $300 on a toothbrush with an app that doesn't work is frustrating. So, I don't use the app anymore, even though it synchs with my Apple Health app. Lastly, the brush head only lasts about 3 months (if you brush 2 times a day). Replacement brush heads are also very expensive, so this is a bit frustrating. I believe that I can stretch the life of the brush head to 5-6 months, but it annoyingly vibrates after every brushing to tell me that I need to replace the brush head. Nothing that disturbed the cleanliness of my teeth, but it is very annoying. So, again a great toothbrush for your oral hygiene, but if you are buying for the other advantages, buy a cheaper model.

Nice brush, really like the app as it tells me how much I've clean in front and in the back of my teeth. My mouth feels alot cleaner everytime I'm done brushing.

The sonic care for me is one of the best purchases of my life. I needed electronic toothbruah which was powerful and does a good job of making my teeth feel clean and these due the job. From the 3 vibration settings to the helpful app to the comfort of the vibration im sure i wont go back to a manual toothbrush again.

Lovely whites that my dentist noticed mean others will see the improvement in my lovely whites too!

The Toothbrush, while crazy expensive is a really good one; however, i had issues with my first one that i had to return in less than 3 weeks. Hopefully that was a fluke and this one will actually be error free. Overall, the cleaning capabilities of it far surpass most regular electric tooth brushes and the app makes me feel like i should actually go through the entire 3 minutes.

Great buy! I love the features and ease of brushing!!!

Best toothbrush I've ever owned. Got it as an Xmas gift and it blows away everything else I've ever used. I had an Oral B rechargeable and it was pretty weak and eventually quit working. Then upgraded to a Waterpik Sonic 2.0. 1st one quit working after a few months. Got it exchanged under warranty and eventually the new one broke as well. The Philips is way more powerful and just does a better job. Mouth feels way cleaner afterwards.

I bought this product when my old Sonicare Diamond started to get really loud and just didn't brush as well anymore. Unboxing it was a treat. The packaging, the handle, brushes and charging case all looked really good. The app worked well with the brush and I was loving it. I particularly loved the tongue brush that came with the box. After about three months, the toothbrush went from a nice quiet buzz to extremely loud and the brush function just wasn't doing it's job. I thought, oh no! Not again. So, I contacted Philips through the app and was given the phone number to contact them. The support centre for Australia were extremely good. They asked me a series of questions about the toothbrush and what was happening and assessed that I needed a replacement handle which they organised very quickly. I've had the replacement for about two months and it's going well. The toothbrush is awesome and does what it says it will do. My gums feel healthy, my teeth look whiter and I'm pretty happy in general with the product. I also trust Philips to replace the handle should anything go wrong again. Fingers crossed.

The Sonicare owns the electric toothbrush game. This toothbrush makes your teeth feel fresh after every use. It even has an app that will literally follow the toothbrush and show you where you should be brushing and how long. Choosing not to use the app doesn't take away anything at all, but it keeps you in check. Teeth are important and making em look good, this toothbrush will help. Your dentist will thank you.

This is high tech. I love the information you can get from the app and how it syncs your brushing to the app and gives you feedback. I also love how the battery is rechargable and has a wireless charging stand it sits on. It's awesome for traveling as well, it has its own protective case. Yes it's expensive but if you invest in keeping your teeth healthy it's a great purchase.

Feels just like getting a cleaning from the dentist.

Love Sonicare! Always a great experience and great innovation.
