Brushing, thankfully, “disrupt[s] the bacteria so it doesn’t stay in place,” she says, because if left in place, it starts to attack your teeth. Plus, the longer that plaque sits in one place, the more likely it is to become tartar, “that hard, yellow, rough material you sometimes feel in between your teeth” that can cause inflammation and bleeding in the gums, she says. Leave that untreated for too long, and you could risk losing teeth.
So brush before you go to sleep.
