Sonicare technology generates 31,000 bristle sweeps per minute. Laboratory studies show that it removes harmful plaque bacteria up to 4 mm beyond the bristle tips -- even below the gum-line.

The Elite brushes have a tapered, lightweight handle, angled neck and advanced brush head design, making brushing more effective and enjoyable.

Sonic Technology
Inspired by the technologies of much more expensive dental equipment, Sonicare creates dynamic fluid cleaning action. It works like tiny, but powerful sonic waves, dislodging plaque that isn't normally reachable by a manual brush, or the oscillating or rotating movement of other power brushes. In fact, dynamic fluid cleaning action can actually make it easier to clean plaque below the gum-line. The bristles on a Sonicare play an important part as well. Their high-velocity movement creates the dynamic fluid cleaning action, while allowing for direct contact with each tooth. Sonicare's bristles are also designed to be extra gentle on teeth and gums.

Smartimer
Smartimer is the automatic shut-off feature in your Sonicare brush that helps encourage you to brush for two minutes, which is the dental professional recommended brushing time. It's simple -- after two minutes, your Sonicare shuts off. If at any time during brushing you momentarily stop the brush to rinse or apply more toothpaste, the Smartimer pauses its timing so that you can pick up where you left off. Although two minutes is recommended for optimal results, you can always stop or restart the brush at any time by pressing the power button. Whenever the handle is placed in the charger, the Smartimer automatically resets to ensure a full brushing cycle the next time you use it. The Smartimer also automatically resets itself if you stop your Sonicare toothbrush for longer than 45 seconds.

Easy-start
Because the sensation created by Sonicare's dynamic fluid action is unique, Sonicare has a feature that lets your gums get accustomed to it over the first 12 to 14 uses. All Sonicare models come with the Easy-start feature activated, which helps you adjust to brushing with Sonicare. The Easy-start feature is active on your brush if you hear 2 beeps immediately after turning on your Sonicare. Once you reach optimal brushing power, you will no longer hear the double beeping at the beginning of your brushing routine.

Quadpacer
Quadpacer makes sure that you brush all four quadrants of your mouth evenly and thoroughly. At 30-second intervals (30, 60 and 90 seconds for a 2-minute brushing cycle), you will hear a short beep and a pause in brushing action. This is your signal to move to the next section of your mouth. Quadpacer makes it easy to clean all areas of the mouth equally well.

Recharge Gauge
If your Sonicare features a Recharge Indicator, and the handle is placed into the charger, the charge indicator LED will blink green as the battery charges. When the battery reaches full charge, the charge indicator LED will glow steady green until the handle is removed from the charger base. When your Sonicare is turned on or off, the charge indicator LED will blink yellow if the battery charge is low. You will also be notified, via three rapid beeps, that you have three or fewer brushings remaining.

Dual Speed Control
This feature lets you set the brushing power to work with your needs. Choose normal speed for optimal plaque removal and reduced speed for gentle cleaning of sensitive areas.
