Key Features

  • Employing the BrushSync mode-pairing**, the Sonicare plaque toothbrush head optimises its intensity level and brushing mode to suit your needs.
  • For easily determining when the Sonicare optimal toothbrush head needs replacement, its blue bristles fade away to a white colour, prompting you to change it for a fresh brush head.
  • With a click-on design, this optimal plaque toothbrush head allows you to quickly replace the brush heads.
  • The Philips Sonicare toothbrush head is suitable for use with the DiamondClean, FlexCare Platinum, PowerUp, ProtectiveClean, EasyClean, and more.
