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.
SenseIQ Technology helps balance your brushing style and senses your pressure, motion and coverage up to 100 times per second while you brush. If you apply too much pressure, the toothbrush will step in and automatically adjust the intensity level, helping to protect your teeth and gums.
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.

Amazing cleaning job - expensive but worthy
Just upgraded from a 6100 that I've had for many years that finally died. I managed to fix it myself (thanks YouTube) before the 9900 arrived but figured I'd give it a shot anyhow. The 9900 is a huge, huge upgrade. The app is nice and all (especially for changing modes on the brush), but really this toothbrush just does an incredible cleaning job. It's expensive, but so far a worthwhile investment. It does a much deeper clean than any other Sonicare I've had.
Pros
Amazing cleaning efficiency. Sleek design.
Cons
Expensive. Travel case doesn't fit when then cap is on the brush head - that should be fixed.

The best of all Sonicare
I had the Sonicare 2200 and was satisfied. This one changed everything. It tells you where you miss and make you do touch-up. Even my dentist was impressed.
