Lowers Gingival Recession Risk

A unique toothbrush head cleans teeth and gums more effectively by cleaning all surfaces of the tooth in the same motion. The innovative design uses stiffer, curved bristles that perfectly conform to each tooth’s shape, allowing the toothbrush to clean the grooves, under the gums and even surfaces between teeth. The redesigned cleaning head minimizes force on gingival tissue and dentin, thereby lowering the risk of gingival recession and dentinal abrasion.
