Do I have to floss? Is brushing not enough?

Flossing reduces the number of bacteria in your mouth in and around the gum and teeth. There are millions of these microscopic creatures feeding on food particles left on your teeth. These bacteria live in plaque which can be removed by flossing. Brushing your teeth gets rid of some of the bacteria in your mouth and on top of your teeth. Flossing gets rid of the bacteria the toothbrush cannot get to like the tiny spaces in between teeth. A build-up of food on and between the teeth can lead to plaque and then decay.
