The Source toothbrush provides an All-Over-Mouth clean that leaves you feeling like you just went to the dentist. With 5000 premium bristles (200% more than an ordinary toothbrush), The super soft, wide head of fanned-out bristles helps improve gum health by massaging sensitive gums while brushing. Healthy gums help reduce the risk of heart disease.
