Why are the bristles of the Xiaomi Oscillation Electric Toothbrush Pro slightly splayed?

The bristles of the Xiaomi Oscillation Electric Toothbrush Pro are made using copper-free planting technology. During manufacturing, the bristles are first polished and then embedded. Due to pressure during the planting process, slight splaying can occur. This is normal and does not affect cleaning performance. It is safe to continue using the toothbrush.
To use the toothbrush properly and avoid this issue during use, please follow the steps below:
1. Excessive force during brushing is one of the main causes of bristle splaying. Instead of pressing the toothbrush hard against your teeth, let the bristles and oscillation motion do the work. Applying gentle, consistent pressure helps maintain the shape of the bristles and reduces the risk of premature wear;
2. After brushing, place the toothbrush in an upright position in a well-ventilated area. Avoid keeping it in closed containers or damp environments, which weaken the bristles and promote deformation over time due to trapped moisture;
3. Replace the brush head every 3 months to ensure optimal cleaning performance and gum protection.
