Thanks to their original design and flexible brush, they offer unique accessibility and effectiveness. They can be easily inserted between teeth and molars to remove food debris and for general cleaning. They also stimulate blood circulation in the gums without damaging crowns or bridges. Directions for use: 1. Insert the brush between your teeth. Rotate. 2. Gently slide it in a back-and-forth motion from top to bottom. 3. Use the flexible tip to reach your molars.
