Philips HX5350/02 is a rechargeable sonic toothbrush that uses dynamic cleaning action to remove plaque and improve gum health. It features an angled neck brush head and contoured bristles to reach deep between teeth and along the gumline. The easy-start feature gently increases power over the first 12 uses to ease you into the Sonicare experience. The Smartimer helps you follow dental recommendations by encouraging a 2-minute brushing time, and the recharge indicator light provides battery charge status and flashes to tell you when to recharge.
