Flossing is an important oral hygiene habit. It cleans and dislodges food stuck between your teeth, which reduces the amount of bacteria and plaque in your mouth. Plaque is a sticky film that builds up on teeth and contributes to cavities and gum disease.

Although many people brush their teeth daily, not everyone flosses their teeth as regularly as they brush. According to a national poll, about 4 in 10 Americans floss their teeth at least once a day, and 20 percent of Americans never floss at all.

Of course, it isn’t enough to simply floss. It’s important to floss correctly. Improper flossing can potentially damage your teeth and gums. So, if you’re unsure about the right way to clean in between your teeth, here’s a step-by-step guide on the best way to floss.

Break off about 18 to 24 inches of dental floss. To hold the floss correctly, wind most of the floss around both of your middle fingers. Leave only about 1 to 2 inches of floss for your teeth.

Next, hold the floss taut with your thumbs and index fingers.

Place the dental floss in between two teeth. Gently glide the floss up and down, rubbing it against both sides of each tooth. Don’t glide the floss into your gums. This can scratch or bruise your gums.

As the floss reaches your gums, curve the floss at the base of the tooth to form a C shape. This allows the floss to enter the space between your gums and your tooth.

Repeat the steps as you move from tooth to tooth. With each tooth, use a new, clean section of floss.
