so much easier and better than dental floss [SEP] i wondered how my older teeth would take to this would it be too strong and wipe out all my fillings actually it has become a necessary part of my dental care it removes stuff a toothbrush could never dislodge and is a much more pleasant way to have a really clean mouth without the gyrations of dental floss just so much easier to use than dental floss and you get a better result very pleased with this haven t traveled with it i pack light for long weekends
