Why do you have to floss every day?
Flossing is really the only way that you can clean in between your teeth. Most people do know that they are supposed to brush two times a day. However, even with brushing two times a day, you don’t get in between your teeth, and the only way to get in between them is to really get down and use floss or a floss aid to get into the areas between them. When someone is flossing, it is important to make sure that they are getting down and really hugging the teeth, not just making sure that the floss clicks in between the teeth, but hugging the teeth. That is most effective at getting the plaque off of the teeth.
How often should you floss?
Floss once a day. I recommend that people brush twice a day, brush once in the morning after breakfast, and floss in the evening and brush right afterwards; the last thing that they do before they go to bed.
