The Philips Sonicare 6100 Rechargeable Sonic Toothbrush model HX6877/23 is a premium electric toothbrush designed to provide effective and gentle oral care. The Smartimer feature ensures that you brush for the dentist-recommended two minutes by automatically turning off the toothbrush after this time. The Quadpacer interval timer prompts you to brush each quadrant of your mouth evenly, ensuring thorough cleaning. This high-frequency motion creates gentle but effective cleaning action that reaches deep between teeth and along the gumline for superior plaque removal and improved gum health.
