Philips Sonicare DiamondClean Smart 9300 Electric Toothbrush, Sonic Toothbrush with App, Pressure Sensor, Brush Head Detection, 4 Brushing Modes and 3 Intensity Levels, Rosegold, Model HX9903/65

Absolutely blown away with this electric toothbrush. I honestly didn't buy one of these for years because I thought it was being hyped for no reason. I decided to purchase one after learning how much it helped my Dad with his teeth after his lingual nerve was severed during wisdom tooth removal. He told me that his dentist noticed a huge difference in how much plaque was on the left side of his mouth (the side that was damaged due to the nerve sever). I was sold. I have been using this brush for maybe a year and I have not had one cavity since using it. My teeth feel cleaner right after I brush. I can tell a difference and my dentist can too. This toothbrush gets not only my seal of approval but my dentist's approval too!I should also mention that I enjoy the blue tooth connectivity to the app. It makes sure I brush all sections of my mouth evenly, with not too much pressure or scrubbing. It gives real time feedback as you brush. I found this brush easy to use because of the app. I feel if I didn't have the direction of the app (at least in the beginning) I would have been confused as I was so used to scrubbing my teeth. The charge lasts well over a week. The cute cup charger is a definite bonus because it looks good on my counter.Overall, I highly recommend this toothbrush. Do your teeth a favor and buy one sooner rather than later.

Hard to go wrong with Sonicare, especially their flagship products. I've been using Sonicare since they first hit the market and you couldn't convince me to buy anything else at this point. I've had several models over the years, and I use them until the wear out from regular use and buy another. My last one I actually just bought replacement handles for until it became hard to find them due to that model being discontinued. I'm sure this one will give me years and years of service and keep my dentist from shaming me for not doing as good a job brushing like they used to when I did manual brushing.

I’m on my third high-end Sonicare.Pros:Regular dental cleanings used to take forever with lots of comments from my dental hygienist that I had tons of plaque. That is a thing of the past with this brush. It worksCons:I’m on my 3rd one. They don’t last forever. They will break if u drop them on the head. The part the head connects to can become too loose.They work so well I’m ok buying a new one ever 3 years or so.

This is a nice tooth brush, nice color, quality, and does a great job cleaning teeth. I like the additional cleaning options as well. Very easy to use and stops once you're done.

The Philips Sonicare DiamondClean Smart 9300 is less of a toothbrush and more of a high-maintenance diva that thinks it's auditioning for a role in a sci-fi movie. While it promises to revolutionize your oral hygiene, it often feels like you're babysitting a gadget that’s way too full of itself.Design and Features: Let’s start with the app. Yes, this toothbrush has an app. Because apparently, brushing your teeth now requires Wi-Fi and a degree in computer science. The app nags you like a helicopter parent, pointing out every spot you missed with the enthusiasm of a dentist who’s just discovered plaque for the first time. And the 3D mouth map? It’s like Google Maps for your teeth, except it’s constantly recalculating because you dared to brush in a way it didn’t approve of.Performance: The pressure sensor is supposed to protect your gums, but it’s so sensitive that it flashes red if you so much as think about brushing with enthusiasm. It’s like having a toothbrush that’s afraid of commitment. And the four brushing modes? Let’s be honest, most of us just want clean teeth, not a menu of options that make us feel like we’re programming a rocket launch.Battery Life: The battery life is decent, but the charging glass is where things get weird. Yes, you heard that right—a charging glass. It’s like the toothbrush is trying to be a fancy cocktail at a high-end bar. Except instead of sipping a martini, you’re awkwardly trying to figure out if the brush is actually charging or just mocking you with its blinking lights.Build Quality: For a toothbrush that costs as much as a small appliance, the build quality is surprisingly underwhelming. The brush heads wear out faster than you’d expect, and replacements are priced like they’re made of gold. The whole thing feels like a subscription service you didn’t sign up for.Verdict: The Philips Sonicare DiamondClean Smart 9300 is the toothbrush equivalent of a midlife crisis. It’s packed with features you didn’t ask for, demands constant attention, and leaves you wondering if you’re the problem. If you’re looking for a simple, effective toothbrush, this isn’t it. But if you’ve ever wanted to feel judged by your dental hygiene routine, this might just be the gadget for you.

This tooth brush helps prevent cavities.

This is my second Sonicare toothbrush, I got my other one about 5 years ago and it held up well but doesn’t hold a charge as well now. Love this one, but I don’t use the app or anything.

Excellent toothbrush, but it would be great if they sold a version with the same brush speed and power but without all the tech features, which I never use. I’m not using an app with a darn toothbrush. The heads are also expensive, and it has a feature making aftermarket heads hard to use. This is very much not appreciated.But it does a fantastic job cleaning teeth, which is what I want. Way better than my old Oral B.
