Dento-Dam is a light-cured liquid dam designed to protect gingival and soft tissues during tooth whitening procedures, helping create a safer and more stable treatment environment. With its excellent flowability and appropriate viscosity, it can be easily applied to the desired area and adapts well even to complex surfaces, supporting the formation of a reliable protective barrier. In addition, its excellent elasticity allows the material to be removed cleanly in one piece without tearing, improving user convenience. Beyond whitening procedures, Dento-Dam can also be effectively used for endo-wall formation and rubber dam stabilization during endodontic procedures, making it useful in a variety of clinical situations. Its vivid color also allows easy identification of the applied area, supporting a more intuitive and efficient clinical workflow.
