Achieve up to 100% whiter teeth in just one week with the Philips Sonicare W2c Optimal White toothbrush heads. Designed for superior stain removal, these brush heads are perfect for those seeking a brighter smile and are also ideal for maintaining results after teeth whitening treatments. The brush heads feature a central brush block to effectively remove surface stains from food and drinks, and diamond-shaped bristles to polish teeth. Experience enhanced cleaning performance with our Smart brush head detection feature (when used with compatible Philips Sonicare Smart handles), which automatically selects the optimal cleaning mode and intensity for exceptional brightness. Replace brush heads every 3 months for optimal efficacy; a reminder system is built into Smart handles, or simply monitor the blue indicator bristles which fade to white. These brush heads are designed for easy attachment and removal, fitting all Philips Sonicare toothbrush handles except PowerUp Battery and essence models. Philips Sonicare brush heads and handles work in synergy, leveraging sonic technology for a powerful clean with up to 62,000 brush movements per minute. The high-speed vibrations create micro-bubbles that drive toothpaste deep between teeth and along the gum line for an optimal clean. All Philips Sonicare brush heads are tested for safety and gentleness on teeth and gums. Compatible with Philips Sonicare Series 2 to 3, DiamondClean, EasyClean, FlexCare, HealthyWhite, and For Kids models.
