Colgate ZigZag Deep Clean Manual Toothbrush is designed with V-shaped cross bristles to reach deep between teeth while soft bristles provide a gentle and effective clean. The soft tongue cleaner behind the toothbrush head gently removes odor causing bacteria for oral care that goes beyond the teeth alone. The toothbrush handles are easy to grip for easier maneuvering while brushing your teeth. Remember to change your toothbrush every 3 months.
