Brushing Technique
Wet the brush head and apply a pea-sized amount of toothpaste. Guide the brush head slowly from tooth to tooth, holding it in place for a few seconds on each tooth before moving to the next. The small round head is designed to wrap around each tooth for effective cleaning.
The small round rotary brush head fits better for a deeper clean.

Maintenance
-
Cleaning the Toothbrush
After each use, rinse the brush head thoroughly under running water while the toothbrush is still switched on. Then, switch off the toothbrush and remove the brush head. Rinse both the brush head and the handle separately under running water. The handle is IPX7 waterproof and fully washable, but avoid submerging the charger in water.
-
Replacing Brush Heads
Dentists recommend replacing brush heads every 3 months, or sooner if the bristles become splayed or worn. To replace, simply pull the old brush head off the handle and push a new Oral-B Kids brush head onto the shaft until it clicks.
-
Battery Care
To maintain optimal battery life, store the toothbrush on its charger when not in use, or allow it to fully discharge occasionally before recharging. The Ni-MH battery provides approximately 1 week of use with twice-daily, 2-minute brushing sessions.
Troubleshooting
-
Toothbrush not turning on:
Ensure the toothbrush is fully charged. Place it on the charger for at least 24 hours. If the issue persists, contact customer support.
-
Weak performance or reduced rotation:
This may indicate a low battery. Place the toothbrush on the charger for a full charge. If the brush head is old or worn, replace it with a new one.
-
Charger not working:
Check if the charger is properly plugged into a working 220-240V outlet. Ensure there is no debris obstructing the charging contacts on the handle or charger.
