Sonicare's Advance 4300 (previously known as the QP-3) cleans with an ultrahigh-speed motion, leaving teeth feeling sparkling fresh. Extra-soft bristles let the user apply as much pressure as desired, making the Sonicare perfect for people with sensitive teeth, braces, and implants. While proven to be as or more effective than manual brushing for removing plaque and preventing gingivitis, the Sonicare Advance is also guaranteed to remove 80% of tobacco, tea, and coffee stains in just 28 days. The 4300 features the Smartimer, which shuts off the brush automatically after two minutes, as well as the Quadpacer interval timer, which beeps every 30 seconds, allotting each quadrant of the mouth equal brushing time. The 4300 includes one standard-size brush head, a charger base, a travel case, and a soft-grip handle that holds its charge for up to two weeks, making it ideal for travel. A two-year warranty covers the handle and charger against defects.
