How often should I brush and floss?

The general rule for brushing and flossing is the more the better. In an ideal world you would brush and floss after every meal but normally convenience restricts that. The unwritten rule is to brush twice a day, once in the morning and once before you go to bed and to floss at least once a day. It is important to clean your oral cavity before going to bed because that is when bacteria can affect your teeth the most.
