Amazon.com Review: Sonicare's Advance 4100 (previously known as the PS-1) 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 Smartimer function takes the guesswork out of how long to brush by automatically shutting off the brush after two minutes. The 4100 includes one standard-size brush head, a charger base, and a 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. --Ann Bieri

Best sonic toothbrush on the market. Far superior to the newer Sonicare series, which have brushes too small for a normal sized male mouth.
