1. It is best not to use an electric toothbrush for more than 2 minutes. Brushing your teeth for too long can damage your gums.
2. The use of an electric toothbrush requires attention. If it is too strong, the brush head will be damaged more quickly. Put the brush head on the tooth surface and control it to a force that suits you.
3. When using an electric toothbrush, please pay attention to the angle, aim at the direction and position of the brush head during use, and try not to leak.
