All Stoddard interdental brushes are specially designed to clean thoroughly in the wider spaces between teeth and around bridges and braces. They are manufactured using only the highest specification materials. High tensile strength, plastic coated, stainless steel wire, at the core prevents the brushes from bending. For longer life the bristles are made from the same memory retentive nylon as used for toothbrushes. The brush is locked to the handle using a revolutionary production process making it virtually impossible for them to separate. The brush is easy to bend enabling full access to the interdental spaces in between the rear molars.
