GUM fine floss is designed to remove dental plaque from areas between the teeth most commonly missed by tooth brushing alone. If dental plaque is not removed frequently it can cause inflammation of the gums and lead to gum disease. GUM fine floss is a thin, shred-resistant dental floss that easily slides between tightly spaced teeth and under the gum line. Special 'S' twist fibers give durability and spread ability to disrupt plaque deposits and carry them away. Between-teeth cleaning is recommended by dentists and dental hygienists to remove the dental plaque that toothbrushes alone cannot reach between the teeth.
