Why brush with one set of bristles when you can brush with three? TropiClean Fresh Breath TripleFlex™ Toothbrush contains three sides of bristles to give the teeth a 360-degree clean, ensuring that no surface is left uncleaned. Brush away plaque and tartar 3X faster when paired with Fresh Breath Brushing Gel. Give your pet the dental care they deserve by repeating brushing sessions weekly.
