Cleaning in between teeth
Philips Sonicare brush heads are vital to our core technology of high-frequency, high-amplitude brush movements performing over 31,000 brush strokes per minute. This dynamic cleaning action drives fluid deep between teeth and along the gumline, for a thorough yet gentle cleaning.
This Philips Sonicare toothbrush head features extra-long, high-density bristles to target hidden plaque caught deep between teeth and other hard-to-clean areas.
At first glance it may not be obvious, but brush heads lose stiffness and gradually wear down over months of normal use. Our blue reminder bristles fade to white and help patients recognize when it's time for a replacement. For optimal results, replace brush heads every three months.

Small swap big clean
These Sonicare brush heads have been a great choice for my daughter. The bristles seem to really get in between teeth and along the gum line, which is exactly the kind of spot that's easy to miss with a regular brush. She still gets a gentle, thorough clean and hasn't complained about them being harsh on her gums. My favorite part though is that Sonicare heads fit all of their toothbrush handles, so I can restock for the whole family at once without having to track down which style goes with which brush. It makes replacing them so much simpler when everyone can just grab a new head and go. Such a small thing but it really does make life easier! I'm looking forward to her next dentist appointment to see if her new brushing habits are noticed! Thanks to the Stellar Product Testing Panel for allowing me to test these toothbrush heads.

Makes a difference
I liked these tooth brush heads. To be honest, I really love the Sonicare toothbrush anyway, so I wasn't sure how much of a difference these heads were going to make when the Stellar Product Testing Panel folks sent them to me to try. But these heads do make a difference. The longer bristles on the Intercare combined with the slender head of the Sonicare anyway really allows it to get between the teeth. Visually, you can even tell the difference in the front teeth; it looks like I flossed. I had a really hard time flossing my back teeth, and I feel like this is making a difference there especially. I am actually excited to show off for the dentist next week. My husband just ordered a Sonicare, and we will be buying these for him as well.
