Although recent news reports have questioned the benefits of cleaning between your teeth, using an interdental cleaner (like floss) is an essential part of taking care of your teeth and gums. The U.S. Department of Health and Human Services also reaffirmed flossing as “an important oral hygiene practice” in an August 2016 statement.

The American Dental Association recommends cleaning between your teeth once a day. This is important because plaque that is not removed by brushing and flossing can eventually harden into calculus or tartar. Flossing may also help prevent gum disease and cavities.
