I was not flossing enough to please my dentist so she recommended this. It takes a while to get used to with all that water rushing in your mouth but it does a thorough cleaning.
My dental hygienist recommended purchasing a water pic to help restore my gum health. My gums had deep pockets and with the daily and twice daily use my gums are healthy once again. I chose this portable model because I did not have the space for the tank style. I love its portability, easy fill and I charge it once a week overnight. It feels great! I enjoy the gum massage from this unit as well as I receive the health benefits.
