Butler Gum Activital Toothbrush Medium eliminates dental plaque in the most difficult access areas with efficiency. The micro-thin bristles gently penetrate into all crevices - including interdental areas and below the gumLine - to remove plaque without the abrasive damage of regular bristles. The advanced ergonomic handle design, with slender neck, absorbs excess brushing force allowing gentle brushing as recommended by dentists to preserve gums from damage. The super thin brush head is designed to easily access all areas of the mouth.
