Customer Ratings & Reviews

The brush and app work very well with eachother and comes withqb convenient carryint case for trips. A little expensive but the brush is relatively cheap and lasts a long time before needing to be replaced. App comes with helpful tips for proper oral health. A worthwhile investment

It's good -- my teeth definitely feel clean after using it, but not it's not perceivably better than older/cheaper models. Plus, for users of older models, this one uses an unfamiliar timing system for when to switch between zones of your mouth. Instead of 4 zones for 30 seconds each, it now splits it into 6 zones (upper left, upper middle, upper right, bottom right, bottom middle, bottom left) for 20 seconds each, and for each of those 6 zones, you're expected to switch from the inside of the teeth to the outside on your own. It would be better if they separated it into 12 zones (inside and outside for each of the 6 zones listed above) for 10 seconds each rather than requiring the user to remember to switch on their own halfway through a 20-second period.

I was able to purchase this on sale, and I was still skeptical of spending this much money on an electric toothbrush. I had a basic Sonicare years back and didn't think that much of it - it was just "ok". I tended to go back to a manual toothbrush more often and just used the electric occasionally. I think it was because the brush head felt too small and the handle was bulkier. The 9900 Prestige feels more like a normal size and the handle itself is smaller and lighter. I also thought it was kind of hokie with the "smart" features, like "who REALLY needs that?" However it's a game changer and it is absolutely amazing. I've only been using it three days now, but I LOVE the smart features. I didn't realize I had areas that needed more attention - I always felt like I was hitting everything I needed to. It seems silly but now I look forward to brushing my teeth and getting that "fresh from the dentist" feeling every time and know what areas I need to pay more attention to. Highly recommend!

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.

I have had 6 or 7 different Sonicare toothbrushes throughout the years but THIS ONE is a HUGE upgrade! I’m so impressed that it’s so much higher quality and tech than my previous ones. The optional app is easy to use and set/up couldn’t be easier! My teeth feel so clean and my breath is greatly improved.

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.

Great device. The app works well. My only complaint is that sometimes it resets the intensity and you need to put it on the charger to reset. Overall though, I love it and it's well worth the price.

I've been using cheap electric toothbrushes for my whole life and decided to try the Sonicare 9900 Prestige. The quality of the device is incomparable to my old toothbrush. Everything from the materials used to the action of the mechanical components feels premium. I feel like I use significantly less effort when brushing now and achieve better results than I did with my old toothbrushes. The app integration wasn't a selling point for me, and I haven't set it up yet. I would definitely recommend trying it out, especially if you can catch a good sale like I did.

We love these toothbrushes! This one was my husband’s. He adored it. It cleans his teeth so well and makes it do easy. The charger is excellent as is the travel case. Its so handy for vacations!

Heard about this device from my dentist, he's recommended me . Help whitening teeth, deep cleaning tooth and have more great option . You love it. Recommend for everyone.

I really love my Sonicare 9900. I have always been a poor brusher and finally decided that I would take my brushing more seriously after another poor dentist visit. I continue to have that fresh from the dentist clean mouth feeling since using the sonicare. I like that it has sensors and can tell you if you need to focus better on a certain part of your mouth, times you and lets you know when to move to the next section of your mouth and gives you hints on techniques such as moving too fast, too much pressure etc. I have only had it a short time now but so far I do think it is worth the pricetag.

Best tooth brush I have ever had. Works effectively without problem. Quiet, easy to clean, and has a nice feel. Owned the other brand tooth brushes that were at a similar level and found this one to be the best.

Great cleaning with an awesome intuitive app makes for a duo that I’m happy to back. Definitely keeps me more on top of my habits and makes sure that I am getting a good cleaning all around.

Excelente product, the quality and funtions are Great

best toothbrush that you can buy , when you brush your teeth feels like you went to the dentist.Easy to use and the app help when you missed an area that you dont brush your teeth right.

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

Most favorite toothbrush I’ve ever had. Left mine in an Airbnb during my engagement weekend and the owner of the house refused to let us back in for me to get it. I’ve used a temporary brush since, but it’s been horrible. Finally able to repurchase!!!

Great Toothbrush. Very advanced. Lets you know when you are doing something wrong and automatically adjusts to correct pressures, etc... The brush head is excellent on this model. Gets my teeth superclean!

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.

I never used an electric toothbrush before so I have nothing to compare this item with. The first time I used the device it really tickled my mouth and I was not sure if I would be able to continue using an electric toothbrush. I truly felt the difference in my teeth by using this device in a positive way so I did decide to continue to use this device. I have nothing bad to say about this toothbrush. This toothbrush now helps me to wake up in the morning. I follow the guide on my iPhone and I know in the end it is doing its job by really properly cleaning my teeth. I'm very happy with this product at this point Since the
