Philips Sonicare 7300 Series Electric Toothbrush – Next-Generation Sonicare Technology, Pressure Sensor, 12 Brushing Settings, SmarTimer, BrushPacer, 21-Day Runtime, Travel Case, Black, HX7421/07

The Philips Sonicare 7300 Series Sonic Toothbrush is designed for adults who want effective cleaning with a gentle touch, whether you’re upgrading your routine after a dental recommendation or replacing a worn brush. Paired with the A3 Premium All-in-One electric toothbrush head, it delivers up to 2000% more plaque removal¹ and up to 600% healthier gums² for a thorough, dentist-clean feeling every time. Behind that performance sits Next-Generation Sonicare Technology: the motor produces 62,000 bristle movements per minute and adjusts power automatically, so there is zero drop in performance even in hard-to-reach areas. Sonicare Fluid Action drives fluid deep between teeth and along the gumline, reaching where bristles alone cannot for a powerful yet gentle clean. A visual pressure sensor lights up at the base when you’re pressing too hard, so gums stay protected session after session. With 12 brushing settings across four modes, Clean, Sensitive, Gum Health and White mode, and three intensity levels, you can dial in the clean that feels right. The Sonicare toothbrush and app pair seamlessly to deliver guided brushing, tips and tricks, and personalized content that helps you build a consistent routine. The BrushPacer prompts you every 20 seconds to move to a new area; after 2 minutes, the SmartTimer signals you’re done. A brush head replacement reminder tracks how often and how hard you brush, then alerts you when it’s time for a new one. Enjoy up to 21 days of regular brushing on a single charge with the included charging travel case keeping your routine on track wherever you go. ¹ vs. a manual toothbrush ² in Clean mode vs. a manual toothbrush in 2 weeks
