Cleaning your mouth and our environment at the same time. The idea is pretty simple, if you make a quality product, it will last longer and people won't need to throw it away. Our products are made to last which means they are being used longer and not filling up the landfills while still providing you with the excellence you have come to expect from Radius. The source toothbrush reduces waste by 93% with its re-usable handle. The source toothbrush provides an all-over-mouth clean that leaves you feeling like you just went to the dentist. With 4500 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. Ordinary toothbrushes are typically too hard and too small to massage the gums. The head and neck of the Source was designed to be smaller than other Radius toothbrushes in order to target smaller, tighter mouths and brushing styles. The ergonomic handle ensures a relaxed grip that reduces pressure on the teeth and sensitive gum tissue, helping to protect the gum line, reduce receding and bleeding gums and enamel erosion. Available in various materials like recycled wood, paper and dollar bills. Bristles are 100% vegetable-based nylon for a petroleum-free option. Product is BPA-free, Latex-free and phthalates-free.
