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 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.

Excelente product, the quality and funtions are Great

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.

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.

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.

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!

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.

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

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.

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!!!

Phillips sonictooth brush is one best in the industry and best buy made it easy to purchase and it was delivered on time. Also the toothbrush works amazing!

I enjoy using this brush. It has helped me stay consistent on brushing twice a day. I would recommend it to anyone

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.

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!

The best toothbrush I have ever had. It helps to get my teeth really clen. If I miss an area the toothbrush will send me an alert. It helps me understand the areas I need to work on.

Love this toothbrush it does a great job highly recommend

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