Here is a Question: Is it better to floss before or after brushing your teeth?
I had a hard time finding any studies that addressed this question. But flossing first doesn’t seem to necessarily be better for your oral health than flossing after brushing. Neverhelesss dentists still weigh in on this matter.
One spokesman of the American Dental Association, Dr. Edmond R. Hewlett, recommends flossing first. His reasoning is that flossing is unpleasant so do it first to avoid the temptation to skip it. This seemed a very unscientific rational to me – plus people who really do floss regularly don’t find it unpleasant. Diehard flossers (I confess that I am one also) love cleaning out plaque in between their teeth and don’t feel clean unless they do so.
In contrast, Dr. Philippe Hujoel, a professor of oral health sciences at the University of Washington in Seattle, recommends brushing with a fluoride toothpaste, then flossing. That way the floss will maneuver the fluoride in between the teeth.
Flossing reduces gum inflammation, or gingivitis, which can progress to periodontal disease and loss of teeth. It is not clear what effect flossing has on dental decay. Technique is crucial for flossing to reduce plaque. You need to guide the floss along the curve of the gum line at the base of each tooth as well as flossing up and down each tooth.
