The Philips Sonicare premium white brush head gives you a whiter, brighter smile. Designed to work with all snap-on Sonicare models, these replacement brush heads have polishing bristles that remove surface stains to visibly whiten teeth in just 3 days, while you get an exceptional deep clean. Use with a Philips Sonicare smart brush head recognition handle (Philips Sonicare DiamondClean smart) to unlock smart features: smart mode-pairing triggers your handle to select optimal mode and intensity level for exceptional plaque removal; smart brush head replacement technology tracks how often and how hard you brush and will notify you when it is time to replace your brush head. Reminder bristles fade to let you know when it’s time for replacement. Replace your brush head every 3 months as recommended by the American dental association. A fresh brush head every 3 months maximizes the effectiveness of Philips’ unique Sonicare technology.
