The most recommended electric toothbrush is the Philips Sonicare HX6932/10. This brush has been clinically proven to remove more plaque than a manual toothbrush, and it also helps to prevent gingivitis. The Sonicare HX6932/10 features a two-minute timer that ensures you brush for the recommended amount of time, and it also has a quadpacer that pauses every 30 seconds to remind you to move to a different area of your mouth.
