What it is
The expanding floss fits between your teeth. The black threads containing charcoal absorb plaque, which causes bad breath. The unique wave fibers penetrate deep into the gaps between your teeth and in periodontal pockets, tightly adhering to the floss and trapping plaque. This "Thorough Removal Dental Floss" comes with a citrus mint-flavored wax that gently smells of fresh citrus, making it easy for beginners to use! Recommended by dentists and dental hygienists.
Ingredients
Material (thread): Nylon Material (case): Polypropylene Material (cutter): Stainless steel Heat resistance temperature (thread): 60°C
How to use
1) Cut the thread to a length of approximately 40cm and wrap it around the middle fingers of both hands, spacing them approximately 15cm apart. 2) Use your thumb and index finger to taut the thread, approximately 1-2cm apart. 3) Gently move the thread back and forth between your teeth, gradually inserting it between your teeth. 4) Once you've passed the area where your teeth touch, insert a small amount into the gap between your teeth and gums (periodontal pocket). POINT! Even healthy mouths have periodontal pockets of approximately 2-3mm, which are prone to plaque buildup. This is an especially important point! 5) After each clean, move the used section and use a new section to clean the next gap. Rinse or brush your teeth after use.
