Well I don’t really know, but if they didn’t work, maybe they wouldn’t have lasted so long? They are good at removing food in hard to reach places, but I’m not sure about plaque. I just use minted waxed floss.
I don’t know I honestly have never tried one but I do want to try one but they’re kind of expensive so I only use my flossers
Yes! It does the exact same thing as traditional floss but with added convenience & comfort. I actually feel it makes flossing significantly easier and effective.
