We bought the Waterpik about a month ago. My husband's dentist recommended that he get a Waterpik because his flossing was nonexistent. He has used it every night since getting it. We'll see what the dentist says in 5 more months.
I was a previous user of the Waterpik years ago and received a new one for Christmas. I love my Waterpik! After each cleaning, my teeth feel as if I just received my cleaning from the dentist and I love that feeling everyday.
I bought it before Christmas. I thought from what I read that it might be good for my stepson' braces & maybe it would help us save on dental work. It came with a travel kit (smaller size too) so perfect, stepson could take to his mom's & use for braces which seemed tougher to keep clean. And we could keep the larger unt here. His reaction when I asked how it was working showed me that it was more than a just "good" thing. It's a little messy until you get used to it, but teeth seem so much cleaner than flossing. When I called to take advantage of the discount on additional heads for registration, the lady said, (when I asked), that she'd talked to people that had them 10-15 years & theirs were still working. So I figured we'd have it long enough to justify buying the extra heads & cleaning wands.
