TePe Original Interdental brushes are designed for cleaning between teeth where a normal toothbrush cannot reach, helping to prevent tooth decay and gingivitis. They effectively clean hard-to-reach places, remove plaque, and freshen breath. For use, insert the brush into the interdental spaces and move back and forth. Each brush features a plastic-coated wire and a rounded tip for safety and comfort. The flexible bristle neck is suitable for use with implants, crowns, bridges, and orthodontic treatments. To use, wiggle or give the brush a quarter turn when inserting into teeth gaps and move back and forth a couple of times horizontally. Rinse with water and air-dry after use, and use the included cap for protection.
