Everyone cleans differently, so we designed this brush head with multi-angle bristles to keep plaque removal on course no matter your technique. Our All-in-One A3 brush head delivers our best cleaning and removes up to 20x more plaque, 15x healthier gums in six weeks, and up to 100% more stain removal in less than two days versus a manual toothbrush.
Philips Sonicare toothbrushes clean gently yet effectively and care for your teeth and gums with 62,000 bristle movements per minute. Sonicare Fluid Action supports the bristles to clean by driving fluid deep between teeth and along the gumline.
This Sonicare electric toothbrush has a light ring at its base that gently lets you know if you're overdoing the pressure. Simply ease off when it lights up to help your gums stay protected.

Diamond Clean Smart 9350- Ideal
We had this same toothbrush for the past 3 years and liked it so much, we bought it once again. The All in One brush heads are pretty amazing.

Pretty darn good
I triale the Philips Sonicare DiamondClean Smart 9350 toothbrush and I am in love. I had a previous rendition of this brush, and this one is top notch. I love the lightweight nature, that was what stood out first after the first few brushes. Compared to other brushes I had, this one gives you a super clean mouth feel, as if you'd been to a hygienist. Love it! So happy that I eas given the chance to try it via Stellar Product Testing Panel. Thank you. It is great that it had 4 and not three modes and of course the pressure sensor is something that every great toothbrush must have. I have sensitive gums and currently a tooth ache, and the brush is still gentle enough for me to brush my teeth with and massage the gums. I am going to the dentist this week and I am sure they will be impressed at the state of the art my teeth are in. Pretty darn good! The best part is that big can also connect to the settings online and keep track of my brushing - what a cool feature!

So clean and fresh
Thank you to Stellar Product Testing Panel and Philips Sonicare for sending me thePhilips Sonicare DiamondClean Smart 9350 toothbrush for free in exchange for my review. I've been a loyal sonicare user for many years and was excited for this opportunity as my last toothbrush recently stopped working (wonderful timing). I've been using a manual toothbrush for the last month or so and after using the Sonicare again I noticed white and cleaner feeling teeth. My mouth felt cleaner as well. I appreciate the four different modes ( deep clean and whitening are used most often) and the three intensity levels (I use level 2). As I am a heavy brisher in regards to pressure, having the pressure sensor is very beneficial to me. I love the brushing app as well,.it gives me reminders and tacks my brushing habits!
