Clinically proven to improve gum health in three ways: reduces redness, swelling and bleeding. With superior plaque removal along the gumline, this toothbrush can help reduce gingivitis up to 100% better than a manual toothbrush in just two weeks. Removes up to 6x more plaque along the gumline than a manual toothbrush. Philip's sonic technology creates a unique dynamic cleaning action that drives fluid deep between teeth and along the gumline for a thorough-yet-gentle clean. This Philips Sonicare power toothbrush features a special Smartimer to help you meet the dentist-recommended brushing time of two minutes. Features a Quadpacer interval timer to help encourage thorough brushing of the entire mouth. The toothbrush beeps every 30 seconds, signifying that it's time to move to another area of the mouth. With three customisable intensity settings (low, medium and high) you can select the right power level to ensure that brushing along the gumline is comfortable. After 1.5 seconds of brushing, you will have to push the button twice to switch modes - once to pause and again to switch. The gentle motion of this Philips Sonicare power toothbrush is safe for dental work, including orthodontics, implants and veneers, so you can brush without worrying.
