I didnt even know they gadgets like this existed but after suffering with eating disorders for a number of years my teeth and gums are not as healthy as they should be for my age.I've been using the irrigator for a few weeks now. My teeth feel much cleaner after using it. Even my dentist (who advised me to purchase one and I am glad I did) has told me that my teeth and gums are in a much better condition. However at first, it made my gums bleed a bit, but after a while gums get used to it. And as I understand it's a common process of healing, you wash out all bacterias which cause problems and gums become more firm and tight.
Much better results that just using regular dental floss. This water flosser is portable and easy to use. Wish I’d discovered this many moons ago
