Benefits of ADA accepted water flossers over regular string floss:

  • Can remove more dental plaque between your teeth and along your gum line
  • Help prevent and reduce gingivitis between your teeth
  • Massage your gums, which can help improve gum health 
  • Convenient and quick cleaning
  • Ideal for people with limited dexterity (moving abilities) or arthritis
