刷牙
刷牙是清洁牙齿的行为。
很多人都以为一早起来必须要刷牙，但其实正确的刷牙时间应该是吃完食物后。只要口内有食物残留，细菌就会滋生，提高蛀牙风险。所以光顾着起床睡前刷牙而不在饭后刷牙会弱化对牙齿的保护。
- 每天刷牙3次（早、中、晚）。
- 每次刷牙3分钟。
- 每次餐后3分钟刷牙。

Tooth brushing 刷牙
Tooth brushing is the act of scrubbing teeth with a toothbrush equipped with toothpaste. Since only two thirds of the outer tooth can be reached by a toothbrush, interdental cleaning (with floss or an interdental brush) can usefully accompany tooth brushing. Together, these two activities are the primary means of cleaning teeth, one of the main aspects of oral hygiene.
