Will it hurt if the toothbrush bucket is too deep?

Brushing cups deeper will not cause harm. The water splash produced when brushing your teeth with a toothbrush will not cause damage to the gums and oral tissues. However, if the toothbrush rod is too long during use, causing water at the bottom of the brushing cup to splash onto the brusher's clothes, it may cause some inconvenience or pollution. Therefore, in order to better maintain hygiene and facilitate use, it is ideal to choose a brushing cup with an appropriate depth.
