Yes
If you want to keep your teeth and your body healthy, yes. Using dental floss to clean the floss between teeth and under the gum line will not only make the corn sticking there during dinner but also help prevent gum disease and more serious health problems. The use of dental floss helps control bacteria associated with chronic systemic inflammation, which is a serious risk factor for heart disease, stroke, lung disease and premature birth.
By the way, don't believe that washing with mouthwash is as good as flossing. A study sponsored by the famous anti-corrosion mouthwash manufacturer found that when sw beat flossing, a later study found that dental care procedures, including brushing, flossing and using preservative mouthwash, cut plaque into 50%. Better to use floss or mouthwash.
