Flossing is important to oral hygiene. However, flossing may be neglected, for a variety of reasons.
People may not floss as often as they need to. People may not be flossing because they do not see the floss. People may not be flossing because they feel it is too much trouble to get the floss. People may not be flossing because they feel flossing is boring or troublesome.
People may not floss as long as they need to. People may be flossing for a shorter time than they believe they are flossing.
What is needed is a device which will facilitate flossing.
