If the Xiaomi Oscillation Electric Toothbrush Pro stops working during use, it can be due to the following reasons:
1. The toothbrush automatically pauses every 30 seconds to remind you to switch brushing areas. This is normal behavior;
2. Excessive pressure during brushing can trigger the overpressure reminder. The toothbrush will then reduce its vibration to protect your teeth. We recommend brushing with light to moderate pressure, as continuous force can lead to issues like wedge-shaped defects or gum damage;
3. Improper brushing pressure or technique can affect the vibration performance. It's best to brush gently without applying excessive sideways force to the brush head, as this can deform the bristles and reduce cleaning effectiveness.
It is recommended to use the Bass technique: angle the bristles at 45° to the gum line and move the brush slowly. Avoid brushing too hard, too fast, or with too much sideways pressure to protect both your teeth and gums.
