Deep cleaning needs a special approach and this C3 brush head uses a cluster of dense, stiff bristles at its center in pentagonal shape to whiten and polish your teeth, for up to 100% more stain removal in three days. It also removes up to 10x more plaque than 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.
It's easy to brush too hard, so this Philips Sonicare toothbrush has a smart optic sensor to detect excessive pressure. If you're brushing too hard, it will let you know trough gentle vibrations as a reminder to ease-off the pressure to help your gums stay protected.

The Panasonic Sonic Care 9000 saved my teeth.
My dental hygienist recommended the Philips SonicCare 9000 model. All the tech numbers are there to read so I won't get into them. Being diabetic my saliva carries excess sugar. Also, having acid reflux is another possible reason that could affect the health of my teeth and gums. So I purchased the 9000 model. I got lucky and got it on sale. $125 instead of $250. I also purchased the Philips brush instead if the off brand. Anyways, what a huge difference. I used a manual tooth brush up until the age of 60. Someone else said it before me, but it feels like I left the dental hygienist's chair after every brushing. And the most difficult place to brush, the bottom inside of my front teeth, incredible. After a month you can usually feel the plaque building up with your tongue with a manual tooth brush, but not the 9000 model. Wish I would have listened and started using the 4000 model when it came out and worked my way up. Would have saved a lot of money, pain, discomfort and dental work. Better late than ever. Even at full price I highly recommend the Philips Sonic Care 9000.
Pros
Everything. It will save your teeth from cavities and help prevent gum disease.

In my opinion none.
