Built-in Timer
The toothbrush features a two-minute timer with 30-second intervals to ensure a complete clean of all four quadrants of your mouth. A short stuttering sound indicates when to move to the next quadrant. A long stuttering sound indicates the end of the recommended two-minute brushing time.
Maintenance
Cleaning the Toothbrush
After each use, rinse the brush head thoroughly under running water with the handle switched on. Remove the brush head and rinse both the handle and the brush head separately. Wipe the handle with a damp cloth.
Replacing Brush Heads
Dentists recommend replacing your brush head every 3 months, or sooner if the bristles become splayed or frayed.
To replace, simply pull the old brush head off the handle and push a new one on until it clicks.
