The Philips Sonicare G2 Optimal Gum Care toothbrush head is perfect for those who want a gentle yet optimal plaque removal experience. The outer bristles gently remove plaque from the gumline. Densely packed, high-quality bristles give you an extra gentle brushing to remove plaque along the gum line to improve gum health up to 100% more than a manual toothbrush. And the specially curved power tip makes reaching the teeth at the back of your mouth a breeze. Youll always get the best possible clean with Philips BrushSync mode-pairing feature. The Philips Sonicare G2 Optimal Gum Care brush head syncs with your BrushSync enabled Philips Sonicare toothbrush handle, selecting the optimal brushing mode and intensity level for exceptional gum care. All you need to do is start brushing. Brush heads become less effective after 3 months use, but with BrushSync youll be reminded before this happens. Your smart toothbrush will track how often and how hard you brush and will notify you when its time for a replacement. Dont have a smart Philips Sonicare toothbrush? Just monitor your blue replacement bristles -- when they turn white youll know its time for a fresh brush head. Your Sonicare brush head and handle are the ultimate team. Enhancing Philips sonic technology, they give you unrivalled cleaning. High-speed vibrations in your toothbrush handle power up to 62,000 brush movements per minute that whip up your toothpaste into gentle cleaning bubbles, driving them deep between your teeth and along the gum line for exceptional cleaning. Your Optimal Gum Care brush head fits perfectly with any Philips Sonicare toothbrush handle, except PowerUp Battery and Essence. Simply click on and off for easy replacement and cleaning. All Philips Sonicare brush heads are safe and gentle on teeth and gums. During tests, each brush head is put through its paces to ensure durability and an exceptional performance every time you brush.
