The Sensodyne Interdens Dental Sticks are not a normal flossing product. They are actually thin pieces of wood, which have been treated so they won’t crack or splinter, which you can use to scrape plaque from the gaps between your teeth and below the gum line.
Dentists accept that stimulation of the gum tissue can help keep it healthy; massaging the gums with these Sensodyne Interdens Dental Sticks will help get the blood flowing into damaged or sensitive gums, ideally making them much healthier.
The Sensodyne Interdens Dental Sticks have also been coated with an anti-bacterial substance to help kill off damaging bacteria in the mouth, which have been found to be a major cause of sensitivity in teeth and gums. This also gives the sticks a pleasant medicinal flavour as you use them.
