Cleaning your mouth and the Environment at the same time! The Source Toothbrush reduces waste by 93% with its re-usable handle made from 50% Recycled Plastic combined with 50% Recycled Natural Fibres. 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), the soft, wide head of fanned out bristles helps improve gum health by massaging sensitive gums while brushing. The head of the Source was designed to be smaller than other RADIUS toothbrushes in order to target different mouth types and brushing styles. A long, slim, unbreakable neck allows for a longer reach for hard to reach back teeth. The ergonomic handle ensures a relaxed grip that reduces pressure on the teeth and sensitive gum tissue, helping to protect the gumline, reduce receding & bleeding gums and enamel erosion. Reversible handle allows for both Right and Left-handed brushers. Bristles are 100% Vegetable Based Nylon for a petroleum free option. Product is BPA Free, Latex Free and Phthalates Free.
