The Philips Sonicare HX7110/01 from the 5500 series is an electric toothbrush designed to provide a thorough clean through sonic technology. It generates 62,000 brush movements per minute, utilizing Fluid Action to push liquid between teeth and along the gumline for a deeper reach than manual brushing. You can choose between two cleaning modes, Clean and White, depending on whether you want a standard daily refresh or a focus on removing surface stains. To help you maintain a healthy routine, the handle features a Smart Timer that tracks the recommended two-minute brushing duration and alerts you when it is time to move to a different zone of your mouth. An integrated pressure sensor provides haptic vibrations if you press too hard, protecting your gums from excessive force. The device is powered by a Li-ion battery that lasts up to 21 days on a single charge and comes with a dedicated charging base. This white model includes one W Optimal White brush head with medium-stiffness, diamond-shaped bristles specifically shaped to polish away stains. Its oval head design and automatic power adjustment make it a practical choice for adults seeking a consistent, guided cleaning experience.
