Jordan Clinic Brush Between interdental brushes have a unique bristle cut – WaveCut ™. The tapered shape is designed to easily enter the interdental space and to clean around the teeth corners. The wire is also coated with plastic, which makes it flexible and gentle to your gums and enamel, but still strong. The soft rubber handle is designed to give you a comfortable, controlled hold. The brushes are sold in a zip lock bag that is convenient to store. There are 10 brushes in each bag and it also includes a hygienic cap which is convenient to use when transporting the brush.
