These interdental brushes are designed for hygienic and thorough cleaning of narrow spaces between teeth. The 0.4 mm metal bristles meet ISO 0 standards and gently remove food debris and plaque, helping prevent inflammation, tartar buildup, and bad breath. The pink brushes feature an ergonomic handle that ensures easy and controlled use, even in hard-to-reach areas. Suitable for daily care as well as post-dental procedures. Use once a day after regular tooth brushing.
