Tooth brushing

Tooth brushing is the act of scrubbing teeth with a toothbrush, usually equipped with toothpaste. Interdental cleaning (with floss or an interdental brush) can be useful with tooth brushing, and together these two activities are the primary means of cleaning teeth, one of the main aspects of oral hygiene.
