For me, I brush my teeth twice a day. When I get up I usually brush my teeth in the morning and before I go to bed. When I do it that will make me feel more energy than I have because it make me feel fresh all day. And before I go to bed I will brush my teeth and went to bed that will clean me up after a big meal in the evening. Sometime, I brush my teeth before I eat. Because it's make me feel fresh and clean. Besides, I think that every should brush my teeth two time per day for teeth healthy and freshy all day.
