In an interdental brush, the filaments are held between two wire sections (1a, 1b) which are twisted with one another. The wire sections (1a, 1b) have a diameter (D) of 0.3 mm or less and are made of a nickel-free or low-nickel steel. These brushes are distinguished by an increased rigidity and an improved restoring force and are stable even if the wire has a small diameter.
