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

If the bristles of the Xiaomi Oscillation Electric Toothbrush slightly splayed, please refer to the following information:
1. The bristles of the Xiaomi Oscillation Electric Toothbrush are produced using copper-free planting technology. During production, the bristles are carefully polished to ensure smooth and rounded tips, and then embedded securely into the brush head.
2. Due to the pressure applied during the bristle embedding process, slight outward splaying may occur. This is a normal phenomenon and does not indicate a quality issue.
3. Slight splaying of the bristles does not affect the cleaning performance or safety of the toothbrush, and it can still be used with confidence.
4. If the bristles become severely deformed, bent, or worn after long-term use, it is recommended to replace the brush head promptly to ensure optimal hygiene and cleaning results.
