Dental professionals recommend brushing for no less than 2 minutes twice daily.
The Smartimer (R) indicates that your brushing cycle is complete by automatically turning off the toothbrush at the end of the brushing cycle.
How to brush:

1. Before switching the Sonicare on, place the bristles of the brush head on your gumline.
2. Hold the handle with a light grip, switch the Sonicare on, and glide the brush across your teeth.
3. To maximize Sonicare's effectiveness apply only light pressure and let the Sonicare toothbrush do the brushing for you. Do not scrub!
