An interdental brush is the most efficient way to remove plaque between the teeth in a user-friendly way. It's designed to clean the gaps where a regular toothbrush is unable to reach. By only using a toothbrush you clean 60% of your teeth, but by adding an interdental brush to your oral care routine, you will clean up to 100% of your teeth. The TePe Interdental Brush Original Yellow has a larger brush size (ISO size 4) and have a thicker, bendable wire. The interdental brush, which is available in 9 different sizes, can be used for cleaning between teeth, implants, bridges, and crowns. Use daily to keep teeth and gums healthy and fresh.
