Customer Ratings & Reviews

Sonicare for a while now and this brush makes you realize how much of a caveman I was brushing my teeth. This thing is so high tech and sleek and worth it. It comes with a plush outer plastic travel case, two brush heads, charger base, and a cup that sits on the base. Man the way I can toss my brush in the cup and charge alone is super cool. It looks sleek and works super well. The brushing experience is fantastic,l. I’ve never had my mouth feel so clean than after I use this brush. I paired it with the app and I feel that the app is really great for tempo and starting out with the brush. You can feel it pulse differently when it’s time to switch areas but the image gives a visual queue on what area to brush. It also will remind you if it’s too fast or too hard. It really shows how much I really sucked at brushing my teeth. I felt like it was always yelling at me while it was “training” me to brush my teeth. But after a few times it got easier. But this brush definitely upgraded my tooth brushing game. Definitely recommend the upgrade it’s totally work it.

SUMMARY: This is one great toothbrush. I have been a Sonicare Essence user for years and it was time to see if a newer version is better. I can unequivocally say it is. My teeth feel cleaner and I like the options this provides. The con is that, for a toothbrush, it is expensive. And the replacement heads can also be very expensive - especially the premium A3 and C3 heads that came in the box. Details to follow: PACKAGING - Packaging is well done with good illustrations of what is included on the outside of the box - Two brush heads are included - the A3 Premium all in one (plaque removal, whitening and gum care), and the C3 two in one (plaque removal and whitening) - Note that the web site states "The DiamondClean Smart is our best toothbrush, for complete care. Three high-performance brush heads let you focus on all areas of your oral health, and our Smart Sensor technology gives you personalized feedback and coaching." This is a bit misleading because you do NOT get three brush heads. - I would think gum care is very important so would prefer two A3s but not sure in practice how much better the A3 is. - In fact, the brush head choices can be confusing. There seem to be a myriad of choices that I will look further into because the MSRP of the A3 and C3 are expensive. - Philips states you can get a free brush head, but you have to sign up for their subscription head replacement service which I am not a big fan of doing. - The box includes a charging base onto which you can put two holders - a charging glass which you can dump the brush into and a charging stand which I preferred for a clean, upright look. - The box includes a case, but I noticed that some units may come with a travel case with an integrated USB cable. I would have preferred the latter. - Some units may also include a brush head holder. I would have like to have that as well. - The above two items (travel case and holder) are not listed on the box so it isn't misleading, but I do think not providing these with a device this expensive are "skimpy." - The provided instruction booklet is decent. I would have liked it to have more information on brushing modes and the different vibrations the unit makes in the modes (see below) - The device is smaller and lighter than the Essence - a big positive SONICARE APP: - The manual states to install the Sonicare App as the first "getting started" step. It was easy to install, but really, is using the app essential? As I found out, not really. - The app follows the head movement as you brush and shows you which part of the mouth to brush. It follows the pacer "beep" and shows time remaining for each part as you brush. - When complete, the app shows "coverage scrubbing and pressure". You can go back in time to see your brushing history. - It really is not that useful, and for many of my brushings, it shows that data is not available. So this is a bit shaky. - The app shows brushing tips and you can reorder via the app (and web site if you desire) - One knock - there are some modes that you should be able to set with the app such as brushing intensity that you have to do with different button pushing. Why not be able to do this in the app? - There is also no information provided in case another family member is using the same handle. This is also a shortfall. - The App is ok, but I believe that once I start using the brush, I probably won't use it much PERFORMANCE: - This is where the device shines. Performance is exceptional. - The four modes were nice, but I probably will settle on "Gum Care". It is long, but I do like the different sensations the brush provides. - I do wish they were described in a bit more detail in the manual however. I found this on line which is a great description: § https://www.usa.philips.com/c-m-pe/oral-health-care/crm/the-modes-of-your-new-toothbrush#_more_on_modes § What it doesn't say is what are the best brush heads for each mode. - Our Essence brush did one thing. It was good. Some may consider this a bit complex, but I like it. Kudos. - I believe that the vibrations felt in the hand are a bit less than the older Essence as well - another positive. BOTTOM LINE: The Philips Sonicare 9300 DIamondCleand Smart Toothbrush is simply excellent. The cleaning and the way it makes my teeth feel is awesome - much better than my old unit. It is versatile, the app is fine, and there are four good modes from which to choose. I do have a couple of minor nits described above but the only major con is that it is a bit expensive and the brush head replacements are pricey. It can be as simple or complex as you want it to be. But if you want great performance, this is highly recommended. I look forward to my next cleaning with my dentist to see what the hygienist has to say!

I first want to mention that we have used a Sonicare toothbrush for many years, so we are accustomed to the way it works. This model has some noticeable and significant changes from older versions. First, let's address the hardware. The power button now requires a deeper "push" into the case to turn it on. My first few uses I kept catching my thumbnail on the case, stopping me from pressing deep enough. My nails are kept trimmed as most men do, so nothing excessive. The older models had a simple base that the main body simply sat on for charging, with a short pin extending from the base to hold it in place. This model has a new two piece base, with a molded glass holder that fits the shape of the body of the brush. Since it must be aligned correctly to slip in, it's not as simple to position it. Why the glass piece, I have no idea. It's a change for change sake. And there's nothing to hold a brush head if they are changed for a different user. This model uses "smart" brush heads, meaning the generic brush heads I use won't communicate with the base unit so there's no brushing history contained in the app. These brush heads cost (depending on the style of brush) from $10-15 each. Sonicare brushes have always been expensive, but this is really a lot. I'll get into more detail about what they are supposed to provide later. How well does it brush? It's a Sonicare, so it does an excellent job of maintaining tooth and gum health. Compared to my older model, it seems to be a hair less aggressive, meaning it doesn't seem to scrub quite as hard. I'm not saying that's a bad thing, and only my next dental cleaning appointment will tell if it's doing better or worse. I did notice one thing the first time I used it. Sonicare devices have a timer built in to tell you when to move to a different section of the mouth. Previous models had 30 seconds per section, with the mouth divided into four sections. This model has shortened the timer to 20 seconds, and now has six sections for brushing. You still end up with a 2 minute total timer, but it's a change for established users. The app shows which section you should be brushing during each section. Ah yes, the app. The Sonicare uses Bluetooth to link to your device for tracking your brushing. And in my opinion it's next to useless for us. When I first set the app up, I wanted to explore the app before I permitted it to monitor my use. Except it wouldn't let me. When I went through the setup procedure, I reached the point it asked to monitor my use. It had a selection of "not now", but clicking that simply took me back one step. There was no way to bypass that permission and actually get to the app, so I was forced to allow it. The "smart" brush head can tell the app if you're moving your brush too quickly or pressing too hard. The app also maintains a history of your brushing, which in theory might be a good thing. Now, someone at Philips should have realized that it's possible/likely that more than one person would be using the toothbrush, and simply change brush heads for each person. That's what my wife and I have done as long as we've used an electric toothbrush. But the app doesn't have any method of tracking multiple users, so if I looked at the history I would see her use and mine mixed together. Even if I thought the app provided value, that omission makes it essentially useless for us. The app does alert you if you're moving the brush too quickly around your teeth, and that is good information if you're not accustomed to using a toothbrush like this. But that's the only value I can see in the app. I was hoping it might allow modifying the timer and number of zones within the mouth, but no such luck. This is still a good Sonicare toothbrush, and we will continue using it for years. However, we will be continuing our use of generic tooth brush heads, and not be concerned with anything the app provides. If it's going to be used by only one person, the app could have some value for monitoring your brushing. Just remember you will need the device you install the app on nearby with the app open, or you won't track any of your use. My phone is normally about 10 feet away in another room, and it never connected to the Sonicare if it wasn't in the bathroom with me.

This model is light years ahead of my last Sonicare 2100 brush. The base of the brush is now flush and lights up to let you know when you are doing something wrong, like scrubbing. The brush sits in a thick glass base or a thick drinking glass on top of the charging base to charge. The glass makes cleanup easy. You can pick from four dental goals, Clean, Whitening, Gum Health, and Deep Cleaning. The brush has three levels of intensity to pick from. Start off slow and work your way up. This brush links to an app via Bluetooth to help maximize your results. The app includes some concise videos to get you started on how to hold the brush, use it to best clean your teeth, and other topics. The app has a map of a mouth you can display during brushing to guide you to move along to each section of your mouth to efficiently brush your teeth. While brushing, the motor will also momentarily pause the brushing every 30 seconds as a signal to move on to the next area to clean. The app provides real time feedback and coaching to improve your technique and ensure you meet the goal of the program you set. To do this the brush has sensors to tell the app its position, attitude, and the pressure being exerted. I’ve had two Sonicare brushes, read the manuals and the app has still helped improve my technique and timing. This is now my third and best Sonicare brush. The different brush programs help you to meet your goals today and when they may change later. There are three different brush heads included for different goals. At the time I got this, Phillips will send you a free brush head when you register. This is on the more expensive side for a toothbrush, but it’s a much more capable brush. The extra brush heads help defray the upfront cost some. If you feel that your brushing could be better, real-time feedback, tips, and coaching may be worth it. Anything to keep the dentist’s drill away. Since I started using Sonicare brushes, my hygienist has noticed. My dental cleanings at the dentist are less intense and faster.

Review for Philips Sonicare DiamondClean Smart 9300 Black I’ve been using Philips electric toothbrushes for over 15 years now, and my visits to the dentist have shown me how well they work. My hygienist *always* comments on how good my teeth look and how good my “self care” is. I haven’t had a cavity in all that time. Alas, nothing lasts forever, so when I had to replace my older Philips toothbrush, I chose the DiamondClean Smart 9300. It has all the features I’ve known and loved for years, plus some new ones. It comes with two different brush heads - a plaque fighting and whitening head and a premium brush that also aids in gum care. The toothbrush handle recognizes the type of brush you put on it and adjusts its motion accordingly. New for me is the brushing feedback app. I thought after (many) decades of brushing my teeth, there was not a lot that an app could teach me about getting my teeth clean, but I was wrong! The app pointed out areas that I was neglecting because I use only my right hand to hold the toothbrush. When I switched hands as I switched sides in my mouth, I actually improved my technique. I’ve been told by my dentist to use a soft brush and not to press too hard when I brush. The DiamondClean 9300 helps with both. The brushes are all considered “soft” and the handle detects if you are using too much pressure by giving a little “buzz” feedback that you can feel and a light on the bottom of the handle that you can see. It’s easy to know when your you’re using too much force. Although the 9300 has a two year warranty, I’ve found they last considerably longer. Some years ago, I had one that failed within the warranty period, and I was very happy with the Customer Service at Philips. They were polite, professional, and immediately sent me a replacement via FedEx.

The Philips Sonicare DiamondClean Smart 9300 Rechargeable Electric Toothbrush is a high-quality electric toothbrush that is packed with features that have really improved my oral health. In the past, I used to rush through brushing in an attempt to just get it over with which is obviously not the best way to maintain healthy teeth and gums. I’ve never had a cavity before so I figured I was doing good enough, but this Philips Sonicare Smart 9300 toothbrush has really shown me that I can be doing a much better job and I have really noticed the results by taking my time and following along with the app for a much more effective cleaning experience. The microchip in the brush heads allow the toothbrush to send data directly to my phone for personalized feedback and coaching during each brushing session. I had a lot to work on the first few times I used this new toothbrush but over time, I have gotten more used to the proper way to brush and I feel like it has helped improve my oral health tremendously. I don’t know if it’s all just in my head but my teeth just seem to look and feel so much better than they did after brushing in the past with my old electric toothbrush. Either way, I know my teeth are well taken care of now. One of the other cool things I really like about this Philips Sonicare Smart 9300 toothbrush is the charging glass. It is very stylish and comes in handy for rinsing while also effortlessly charging the toothbrush. The travel case that comes in the package is also a very nice feature since it makes it easy to transport the toothbrush and brush heads when travelling. Overall, the Philips Sonicare DiamondClean Smart 9300 Rechargeable Electric Toothbrush is great high-quality electric toothbrush and I highly recommend it!

This is definitely the fanciest toothbrush I've ever used. Pairing a toothbrush to my phone seems crazy. The real benefit to it though, is to help you develop better brushing habits. Of course that still requires some commitment from you, but if you're brushing regularly, but still getting cavities, this may get you on the right track. The catch is, you actually need the app open on your phone when starting a brushing session. The benefit to this is that it will tell you which area to brush, and will keep track of areas you have brushed. This helps with making sure you haven't missed anywhere. Once you've learned the pattern, you can go without the app, and just learn to switch areas when the brush momentarily pauses. It will double pause (if I remember correctly) if you are pressing too hard as well, so it also helps coach you with the appropriate amount of pressure. Once your phone is in range of the toothbrush, it will sync your brushing sessions, but it doesn't keep track of the areas your brushed, but it does track time and overall pressure. If you're really dedicated, it has some other features, such as adding areas of plaque buildup, bleeding areas, potential cavities, and gum recession. The only thing I wish it had was some gentle nudges to brush if I missed/skipped brushing, flossing, etc... It comes with a nice solid glass that you can use for holding the toothbrush, and holds the charger under it, so the toothbrush can charge while in the cup. This also means you could use the cup for rinsing your mouth too (if only I could remember to put it in the dishwasher). The battery is not replaceable. As a matter of fact, they have instructions for removing the battery for recycling, and it involves permanently breaking the bottom of the toothbrush to remove the battery. Planned obsolescence and I don't like it.

I’ve used the basic Sonicare toothbrushes for many years. They have been reliable and long lasting while also being good at what they are made for - brushing teeth. This 9300 series brush adds some genuinely useful smart features while being a more premium product overall than the basic Sonicare brushes I have used in the past. In the box you will find the brush with two heads, a travel case, and a customizable charging “cup”. You can place the brush in the cup or customize it to be more like a stand. The cup/stand piece is washable to keep it clean. The travel case is very premium feeling. The actual brushing experience is exactly as I expected from being accustomed to previous Sonicare brushes. The sonic vibration works just the same and your teeth end up feeling very thoroughly cleaned. The real significant features with this toothbrush come with the Bluetooth and app functionality. I downloaded the Sonicare app and my phone immediately detected the brush. Here, you can keep track of how often and how long you brush, and there is also a clean feature where you can see which teeth you may have missed. This is genuinely useful, as it keeps you on track to brush evenly throughout. It also tells you if you’re moving too fast or putting too much pressure on the teeth. Overall the smart features are easy to use and are genuinely useful, and certainly can help a person maintain better dental health.

Great toothbrush. Has many setting for a clean brush.

Toothbrush is great. Wish the carrying case included charging as in previous versions.

The brush died after 2 years. The button seemed to need to be pressed a couple of times before turning on for about a week. Then it just died. For the amount of money I spent on this my toothbrush should last at least 5 yrs. Very upset bc this was an investment gone to waste.
