The simple fact is that brushing can not reach the tight spaces between your teeth or under your gum-line. If you are only brushing your teeth you are only getting the job half done. Which means you are more likely to have tooth decay, bad breath and gum disease. Flossing is easy and only takes a few minutes out of your day.
How to floss: When flossing do not skimp. You want to use around 18 inches of dental floss. Wind most of the floss around the middle finger on one hand, and the rest around the middle finger on the other hand leaving about 1 inch to floss your first tooth. Floss one tooth at a time. Use your thumbs and forefingers to gently pull the floss from the gum-line to the top of the tooth to scrape off plaque. Rub the floss against all sides of the tooth. Unwind to fresh floss as you progress to the next tooth. Make sure to floss daily.
