Frequently Asked Questions
Will other brush heads fit my Philips Sonicare DiamondClean Smart toothbrush?
All Philips Sonicare electric toothbrush brush heads that snap on will fit your DiamondClean Smart toothbrush. However, not all can be used for Smart mode pairing. Find out how to tell the difference.
Find the Smart brush head icon
A microchip in the Philips Sonicare Smart brush head tells your DiamondClean Smart which one you're using. So if you click on a gum-care brush head, for example, your toothbrush knows to select the optimal mode and intensity for that brush head. You can identify the Smart brush heads by the Smart icon at the base of the brush head.
