The usmile P10S offers three distinct brushing modes:

- Clean Mode: Standard daily cleaning for effective plaque removal.
- White Mode: Designed for polishing and removing surface stains.

5.2 Selecting a Mode
- Press the Power/Mode button once to turn on the toothbrush. It will start in the last used mode.
- Press the Power/Mode button repeatedly within 5 seconds to cycle through the modes (Soft > Clean > White). The corresponding indicator light will illuminate.
- To turn off the toothbrush, press and hold the Power/Mode button for 2 seconds, or it will automatically turn off after the 2-minute brushing cycle.
5.3 Brushing Technique
For optimal results, follow these guidelines:
- Wet the brush head and apply a small amount of toothpaste.
- Place the brush head against your teeth at a slight angle towards the gumline.
- Turn on the toothbrush and gently move it across your teeth, allowing the sonic vibrations to clean. Do not scrub aggressively.
- The built-in 30-second quadrant reminder will pause briefly every 30 seconds, signaling you to move to the next section of your mouth.
- The toothbrush will automatically turn off after 2 minutes, indicating the completion of the recommended brushing time.
- The 3-second anti-splash start feature ensures the brush head starts gently to prevent toothpaste splatter.
6. Maintenance
6.1 Cleaning
- After each use, rinse the brush head thoroughly under running water.
- Remove the brush head and rinse the metal shaft area on the handle.
- Wipe the handle with a damp cloth. The usmile P10S is IPX8 waterproof, allowing for safe rinsing and use in the shower.

6.2 Replacing Brush Heads
Dentists recommend replacing brush heads every 3 months, or sooner if the bristles become frayed. The usmile P10S brush heads feature color-changing indicator bristles that fade over time to remind you when it's time for a replacement.

- Align and push a new brush head onto the handle until it clicks into place.
