Customer Ratings & Reviews

The Sonicare 9900 is a great improvement over the 9700. The best feature is getting rid of the charging glass. These glasses are an accident waiting to happen in a bathroom, especially if there are children, and they are difficult and expensive to replace. I have been using Sonicare brushes for many years and feel that this one is worth the extra cost. The software, which requires a compatible phone, shows areas of your teeth that have been missed. The travel case, charger, is smaller, sleeker, and easier to use than previous models.

So far ive useed to deep clean twice on medium intesity. I feel like i just went to the dentist. Kid you not. My teeth have never felt so clean from using a toothbrush. My teeth feel like I just went to the dentist to get a cleaning. Well worth whatever this costs. You will be spending less time at the dentist for sure

This is the best toothbrush I’ve ever owned. Even better than every other sonicare I had previously for the last 15 years. Very much worth the money. The travel case and charger is awesome. You’ll feel like you just went to the dentist for a cleaning after every use. Recommend 1000%

Best of the best, you can feel the difference of how clean your teeth feel after the first use.

She wasn’t a fan of the Oral B, but can’t stop raving about how clean her teeth feel!

It’s good and expensive. The only complain is charging. Last brush I had more charging than this but it is more slimmer

Great battery life. Easy to handle. Fells comfortable. Easy use.

Smaller and lighter has been great. Much easier to handle.

This is an excellent electric toothbrush, very thorough clean and easy to use. If you are upgrading from an earlier Sonicare model, you will notice that the familiar outer/upper, outer/lower, inner/upper, inner/lower pattern has been split into a more complex 3 zone cycle—this helps you brush more evenly. The brush also senses if you are pressing too hard, another improvement. I don’t use the app—it doesn’t work very well and gives erroneous recommendations.

I didn't know I could buy this type of appliance from Best Buy. The toothbrush is top-notch. My teeth are cleaner than they've ever been without a dentist. My dentist suggested this brand and I am completely happy. It was expensive but I figured I would only buy it once a decade. Hopefully, it lasts that long. I expect it will.

My teeth feel like ive just left the dentist! Amazing toothbrush.

Amazing toothbrush realky cleans and battery last a long time

This is an awesome toothbrush. Used to have sensitive teeth till I started using this brush. The feed back is phenomenal.. would definitely recommend

This thing tells you when you don’t brush enough. It’s great. If you want the best this is for you. Love how I can see the battery percentage on my phone. If you want to save get the lower model. It has the same performance as the model under it but this one has the tech stuff. Great purchase. Love how the travel case is a charger.

Feels like a dentist office visit each time I brush. Each mode offers a different brushing experience. The travel case is super convenient and allows charging while on the go. Love everything about this toothbrush.

Amazing toothbrush that leaves teeth and whole mouth clean. Has lots of features and connectivity to smartphone. Travels really well and battery lasts a long time.

It’s an upgrade from the previous model I had and with the app being accessible, it’s easy to use and for you to keep track on your brushing habits.

Great toothbrush with a wonderful travel/charging case. Makes brushing a joyful event everytime. Finally the mundane has because the highlight of my day.

Great toothbrush .. whole family has one.. highly recommend

Love the design. It doesn't take up much room on the bathroom shelf and the buttons are flush with the handle so no more getting toothpaste into the crevices and making the buttons not work. Love this re-design of the handle. Holds the charge a long time so I usually don't even have to charge it when traveling,
