Bristles with a multilevel, interdental cut help access the hard-to-reach areas. Soft bristles clean well and are gentle on gums. Ergonomic handle is designed to improve control. Medium-head size: between full and compact. Uniquely woven floss with a fresh flavor effectively removes plaque between teeth and below the gum line, places most commonly missed by toothbrushing alone and where tooth decay and gum disease often occur.
