Take a 40-50 cm long piece of dental floss. Wrap it around both middle fingers a few times and support it with your thumb and index finger. Now use both index fingers to guide the dental floss into the interdental spaces. “Hug” the tooth and move the dental floss up and down. Guide the dental floss around the neighboring tooth in the same interdental space to ensure that both tooth surfaces are cleaned. The floss should be fluoridated. Choose unwaxed dental floss, as it is slightly fluffier and therefore has a better cleaning effect.
