6.2 Brushing Technique
Apply a small amount of toothpaste to the brush head. Place the brush head against your teeth at a slight angle towards the gumline. Gently move the brush head across your teeth, allowing the sonic vibrations to do the work. Do not scrub vigorously. The double swing angle sweeping vibration ensures thorough cleaning even in hard-to-reach areas.

After 2 minutes of brushing, the indicator lights on the handle will provide feedback on your brushing coverage. A white light indicates that the area has been adequately brushed. An orange breathing light will highlight any missed brushing areas, prompting you to re-brush those spots for a complete clean.
