Flossing is a crucial part of oral hygiene. According to dental recommendations, you should use four inches (10 centimeters) or more between your teeth and carefully slide the thread under all visible surfaces using steady pressure for 20 seconds.
Flossing should be done at least once per day to remove any build-up of plaque or food debris between teeth where brushing does not reach, but a minimum of twice daily and after meals is highly recommended.
